SwiftUI update navigation bar title color

Question

How to change the navigation bar title color in SwiftUI

NavigationView {
            List{
                ForEach(0..<15) { item in
                    HStack {
                        Text("Apple")
                            .font(.headline)
                            .fontWeight(.medium)
                            .color(.orange)
                            .lineLimit(1)
                            .multilineTextAlignment(.center)
                            .padding(.leading)
                            .frame(width: 125, height: nil)


                        Text("Apple Infinite Loop. Address: One Infinite Loop Cupertino, CA 95014 (408) 606-5775 ")
                            .font(.subheadline)
                            .fontWeight(.regular)
                            .multilineTextAlignment(.leading)
                            .lineLimit(nil)


                    }
                }
            }
            .navigationBarTitle(Text("TEST")).navigationBarHidden(false).foregroundColor(.orange)
            }

I have tried with .foregroundColor(.orange) but it is not working

also tried .navigationBarTitle(Text("TEST").color(.orange))

Any help?

Answer 1

It is not necessary to use .appearance() to do this globally.

Although SwiftUI does not expose navigation styling directly, you can work around that by using UIViewControllerRepresentable . Since SwiftUI is using a regular UINavigationController behind the scenes, the view controller will still have a valid .navigationController property.

struct NavigationConfigurator: UIViewControllerRepresentable {
    var configure: (UINavigationController) -> Void = { _ in }

    func makeUIViewController(context: UIViewControllerRepresentableContext<NavigationConfigurator>) -> UIViewController {
        UIViewController()
    }
    func updateUIViewController(_ uiViewController: UIViewController, context: UIViewControllerRepresentableContext<NavigationConfigurator>) {
        if let nc = uiViewController.navigationController {
            self.configure(nc)
        }
    }

}

And to use it

struct ContentView: View {
    var body: some View {
        NavigationView {
            ScrollView {
                Text("Don't use .appearance()!")
            }
            .navigationBarTitle("Try it!", displayMode: .inline)
            .background(NavigationConfigurator { nc in
                nc.navigationBar.barTintColor = .blue
                nc.navigationBar.titleTextAttributes = [.foregroundColor : UIColor.white]
            })
        }
    .navigationViewStyle(StackNavigationViewStyle())
    }
}

Answer 2

In SwiftUI, you can not change the navigationTitleColor directly. You have to change UINavigation's appearance in init() like this,

struct YourView: View {

    init() {
        //Use this if NavigationBarTitle is with Large Font
        UINavigationBar.appearance().largeTitleTextAttributes = [.foregroundColor: UIColor.red]

        //Use this if NavigationBarTitle is with displayMode = .inline
        UINavigationBar.appearance().titleTextAttributes = [.foregroundColor: UIColor.red]
    }

    var body: some View {

        NavigationView {
            List{
                ForEach(0..<15) { item in
                    HStack {
                        Text("Apple")
                            .font(.headline)
                            .fontWeight(.medium)
                            .color(.orange)
                            .lineLimit(1)
                            .multilineTextAlignment(.center)
                            .padding(.leading)
                            .frame(width: 125, height: nil)


                        Text("Apple Infinite Loop. Address: One Infinite Loop Cupertino, CA 95014 (408) 606-5775 ")
                            .font(.subheadline)
                            .fontWeight(.regular)
                            .multilineTextAlignment(.leading)
                            .lineLimit(nil)
                    }
                }
            }
            .navigationBarTitle(Text("TEST")).navigationBarHidden(false)
            //.navigationBarTitle (Text("TEST"), displayMode: .inline)
        }
    }
}

I hope it will work. Thanks!!

I have searched for this issue and find a great article about this, you could wrap the settings of navigation bar style as a view modifier.

Check this Link .

Notes: I believe you need to update some code in this example, add titleColor parameter.

struct NavigationBarModifier: ViewModifier {

    var backgroundColor: UIColor?
    var titleColor: UIColor?

    init(backgroundColor: UIColor?, titleColor: UIColor?) {
        self.backgroundColor = backgroundColor
        let coloredAppearance = UINavigationBarAppearance()
        coloredAppearance.configureWithTransparentBackground()
        coloredAppearance.backgroundColor = backgroundColor
        coloredAppearance.titleTextAttributes = [.foregroundColor: titleColor ?? .white]
        coloredAppearance.largeTitleTextAttributes = [.foregroundColor: titleColor ?? .white]

        UINavigationBar.appearance().standardAppearance = coloredAppearance
        UINavigationBar.appearance().compactAppearance = coloredAppearance
        UINavigationBar.appearance().scrollEdgeAppearance = coloredAppearance
    }

    func body(content: Content) -> some View {
        ZStack{
            content
            VStack {
                GeometryReader { geometry in
                    Color(self.backgroundColor ?? .clear)
                        .frame(height: geometry.safeAreaInsets.top)
                        .edgesIgnoringSafeArea(.top)
                    Spacer()
                }
            }
        }
    }
}

extension View {

    func navigationBarColor(backgroundColor: UIColor?, titleColor: UIColor?) -> some View {
        self.modifier(NavigationBarModifier(backgroundColor: backgroundColor, titleColor: titleColor))
    }

}

After that, apply like this:

.navigationBarColor(backgroundColor: .clear, titleColor: .white)

I hope it will work.

Answer 4

In iOS 14, SwiftUI has a way to customize a navigation bar with the new toolbar modifier.

We need to set ToolbarItem of placement type .principal to a new toolbar modifier. You can even set an image and much more.

NavigationView {
    Text("My View!")
        .navigationBarTitleDisplayMode(.inline)
        .toolbar {
            ToolbarItem(placement: .principal) {
                HStack {
                    Image(systemName: "sun.min.fill")
                    Text("Title")
                        .font(.headline)
                        .foregroundColor(.orange)
                }
            }
        }
}

Answer 5

Building on the answer from Arsenius, I found that an elegant way to get it to work consistently was to subclass UIViewController and do the configuration in viewDidLayoutSubviews() .

Usage:

VStack {
    Text("Hello world")
        .configureNavigationBar {
            $0.navigationBar.setBackgroundImage(UIImage(), for: .default)
            $0.navigationBar.shadowImage = UIImage()
        }
}

Implementation:

extension View {
    func configureNavigationBar(configure: @escaping (UINavigationController) -> Void) -> some View {
        modifier(NavigationConfigurationViewModifier(configure: configure))
    }
}

struct NavigationConfigurationViewModifier: ViewModifier {
    let configure: (UINavigationController) -> Void

    func body(content: Content) -> some View {
        content.background(NavigationConfigurator(configure: configure))
    }
}

struct NavigationConfigurator: UIViewControllerRepresentable {
    let configure: (UINavigationController) -> Void

    func makeUIViewController(
        context: UIViewControllerRepresentableContext<NavigationConfigurator>
    ) -> NavigationConfigurationViewController {
        NavigationConfigurationViewController(configure: configure)
    }

    func updateUIViewController(
        _ uiViewController: NavigationConfigurationViewController,
        context: UIViewControllerRepresentableContext<NavigationConfigurator>
    ) { }
}

final class NavigationConfigurationViewController: UIViewController {
    let configure: (UINavigationController) -> Void

    init(configure: @escaping (UINavigationController) -> Void) {
        self.configure = configure
        super.init(nibName: nil, bundle: nil)
    }

    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()

        if let navigationController = navigationController {
            configure(navigationController)
        }
    }
}

Answer 6

I took a slightly different approach; I wanted to change only the title text color, and nothing else about the NavigationBar . Using the above and this as inspiration, I landed on:

import SwiftUI

extension View {
    /// Sets the text color for a navigation bar title.
    /// - Parameter color: Color the title should be
    ///
    /// Supports both regular and large titles.
    @available(iOS 14, *)
    func navigationBarTitleTextColor(_ color: Color) -> some View {
        let uiColor = UIColor(color)
    
        // Set appearance for both normal and large sizes.
        UINavigationBar.appearance().titleTextAttributes = [.foregroundColor: uiColor ]
        UINavigationBar.appearance().largeTitleTextAttributes = [.foregroundColor: uiColor ]
    
        return self
    }
}

This requires iOS 14 because UIColor.init(_ color: Color) requires iOS 14.

Which can be leveraged as such:

struct ExampleView: View {
    var body: some View {
        NavigationView {
            Text("Hello, World!")
                .navigationBarTitle("Example")
                .navigationBarTitleTextColor(Color.red)
        }
    }
}

Which in turn yields:

Answer 7

I have developed a small sample of a custom SwiftUI navigation that can provide full visual customisation and programatic navigation. It can be used as a replacement for the NavigationView.

Here is the NavigationStack class that deals with currentView and navigation stack:

final class NavigationStack: ObservableObject  {
    @Published var viewStack: [NavigationItem] = []
    @Published var currentView: NavigationItem

    init(_ currentView: NavigationItem ){
        self.currentView = currentView
    }

    func unwind(){
        if viewStack.count == 0{
            return
        }

        let last = viewStack.count - 1
        currentView = viewStack[last]
        viewStack.remove(at: last)
    }

    func advance(_ view:NavigationItem){
        viewStack.append( currentView)
        currentView = view
    }

    func home( ){
        currentView = NavigationItem( view: AnyView(HomeView()))
        viewStack.removeAll()
    }
}

You can have a look here: for the full example with explanation:

PS: I am not sure why this one was deleted. I think it answer the question as it is a perfect functional alternative to NavigationView.

Answer 8

Use Below Code for Color Customization in SwiftUI

This is for main body background color:-

struct ContentView: View {

var body: some View {

 Color.red
.edgesIgnoringSafeArea(.all)

 }

}

For Navigation Bar:-

struct ContentView: View {

@State var msg = "Hello SwiftUI😊"

init() {

    UINavigationBar.appearance().backgroundColor = .systemPink

     UINavigationBar.appearance().largeTitleTextAttributes = [
        .foregroundColor: UIColor.white,
               .font : UIFont(name:"Helvetica Neue", size: 40)!]

}

var body: some View {

    NavigationView {

    Text(msg)

        .navigationBarTitle(Text("NAVIGATION BAR"))

    }

    }

  }

For Other UI Elements Color Customization

struct ContentView: View {

@State var msg = "Hello SwiftUI😊"

var body: some View {

        Text(msg).padding()
            .foregroundColor(.white)
            .background(Color.pink)

    }
 }

Answer 9

init() {
    // for navigation bar title color
    UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor:UIColor.red]
   // For navigation bar background color 
    UINavigationBar.appearance().backgroundColor = .green
}

NavigationView {
       List {
           ForEach(0..<15) { item in
               HStack {
                    Text("Apple")
                       .font(.headline)
                       .fontWeight(.medium)
                       .color(.orange)
                       .lineLimit(1)
                       .multilineTextAlignment(.center)
                       .padding(.leading)
                       .frame(width: 125, height: nil)

                    Text("Apple Infinite Loop. Address: One Infinite Loop Cupertino, CA 95014 (408) 606-5775 ")
                       .font(.subheadline)
                       .fontWeight(.regular)
                       .multilineTextAlignment(.leading)
                       .lineLimit(nil)
                }
           }
       }
       .navigationBarTitle(Text("TEST")).navigationBarHidden(false)
}

Answer 10

If you have your content as

struct MyContent : View {
...
}

then you can put it like this inside a navigation view with a red background:

NavigationView {
    ZStack(alignment: .top) {
        Rectangle()
            .foregroundColor(Color.red)
            .edgesIgnoringSafeArea(.top)
        MyContent()
    }
}

I will update my answer as soon as I know how to update the title text itself.

Answer 11

Instead of setting appearance() , which affects all navigation bars, you can set them individually using SwiftUI-Introspect .

Example:

struct ContentView: View {
    var body: some View {
        NavigationView {
            ScrollView {
                Text("Hello world!")
            }
            .navigationTitle("Title")
        }
        .introspectNavigationController { nav in
            nav.navigationBar.barTintColor = .systemBlue
        }
    }
}

Result:

Answer 12

Definitely there are already a few good answers, but all of them will cover only part of the job:

1. Great solution from @arsenius - give the good point to start

2. Elegant way from @EngageTheWarpDrive - this definitely improve usability

3. For latest version of iOS and swiftUI @Thahir suggest to use toolbar

Few more suggestions propose to use UIAppearence global config for UINavigationBar - as for me global change is not a good idea and may be not always suitable.

I ended up combining all proposals in to the next code:

1. Create NavigationControllerRepresentable and modifier for navigationBar configuration:

    struct NavigationControllerLayout: UIViewControllerRepresentable { var configure: (UINavigationController) -> () = { _ in } func makeUIViewController( context: UIViewControllerRepresentableContext<NavigationControllerLayout> ) -> UIViewController { UIViewController() } func updateUIViewController( _ uiViewController: UIViewController, context: UIViewControllerRepresentableContext<NavigationControllerLayout> ) { if let navigationContoller = uiViewController.navigationController { configure(navigationContoller) } } } extension View { func configureNavigationBar(_ configure: @escaping (UINavigationBar) -> ()) -> some View { modifier(NavigationConfigurationViewModifier(configure: configure)) } } struct NavigationConfigurationViewModifier: ViewModifier { let configure: (UINavigationBar) -> () func body(content: Content) -> some View { content.background(NavigationControllerLayout(configure: { configure($0.navigationBar) })) } }

2. To modify navigationBar to meet u'r requirements (such as bg color and other props):

    extension UINavigationBar { enum Appearence { case transparent case defaultLight case colored(UIColor?) var color: UIColor { ... } var appearenceColor: UIColor { ... } var tint: UIColor { .... } var effect: UIBlurEffect? { .... } } func switchToAppearence(_ type: Appearence) { backgroundColor = type.color barTintColor = type.tint // for iOS 13+ standardAppearance.backgroundColor = type.appearenceColor standardAppearance.backgroundEffect = type.effect // u can use other properties from navBar also simply modifying this function } }

3. As u can see, here we definitely need some bridge between Color and UIColor . Starting from iOS 14 - u can just UIColor.init(_ color: Color) , but before iOS 14 there is not such way, so I ended up with simple solution:

    extension Color { /// Returns a `UIColor` that represents this color if one can be constructed /// /// Note: Does not support dynamic colors var uiColor: UIColor? { self.cgColor.map({ UIColor(cgColor: $0) }) } }

this will not work for dynamic colors

4. As result u can use this as following:

    // modifier to `NavigationView` .configureNavigationBar { $0.switchToAppearence(.defaultLight) }

Hopefully this may help to someone ;)

Answer 13

I still haven't figured out how to do the foreground color on a per-view basis, but I did figure out a simple workaround for the background color.

If using an .inline title, you can just use a VStack with a rectangle at the top of the NavigationView :

NavigationView {
    VStack() {
        Rectangle()
            .foregroundColor(.red)
            .edgesIgnoringSafeArea(.top)
            .frame(height: 0)

        List {
            Text("Hello World")
            Text("Hello World")
            Text("Hello World")
        }
    }
    .navigationBarTitle("Hello World", displayMode: .inline)
    // ...

Note how the rectangle uses a frame height of 0 and .edgesIgnoringSafeArea(.top) .

Answer 14

Here is the solution that worked for me. You need to start off with a UINavigationController as the rootViewController.

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    if let windowScene = scene as? UIWindowScene {
        let window = UIWindow(windowScene: windowScene)
        let nav = setupNavigationController()
        window.rootViewController = nav
        self.window = window
        window.makeKeyAndVisible()
    }
}

func setupNavigationController() -> UINavigationController {
    let contentView = ContentView()
    let hosting = UIHostingController(rootView: contentView)
    let nav = NavigationController(rootViewController: hosting)
    let navBarAppearance = UINavigationBarAppearance()
    navBarAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
    navBarAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
    navBarAppearance.backgroundColor = UIColor.black
    nav.navigationBar.standardAppearance = navBarAppearance
    nav.navigationBar.scrollEdgeAppearance = navBarAppearance
    nav.navigationBar.prefersLargeTitles = true
    return nav
}

and then in your content view:

struct ContentView: View {

    @State private var isModalViewPresented: Bool = false

    var body: some View {
        List(0 ..< 10, rowContent: { (index) in
            NavigationLink(destination: DetailView()) {
                Text("\(index)")
            }
        })
        .navigationBarItems(trailing: Button("Model") {
            self.isModalViewPresented.toggle()
        })
        .sheet(isPresented: $isModalViewPresented, content: {
            ModalView()
        })
        .navigationBarTitle("Main View")
    }
}

and if you want to change the color at some point, such as in a modal view, use the answer given here

struct ModalView: View {
    var body: some View {
        NavigationView {
           Text("Hello, World!")
           .navigationBarTitle("Modal View")
           .background(NavigationConfigurator { nc in
              nc.navigationBar.backgroundColor = UIColor.blue
              nc.navigationBar.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
           })
       }
    }
}

you can subclass UINavigationController to change the status bar color

class NavigationController: UINavigationController {

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override var preferredStatusBarStyle: UIStatusBarStyle 
    {
        .lightContent
    }
}

Answer 15

.foregroundColor(.orange) - изменяет внутренние представления NavigationView.

But to change the navigation view itself, you need to use UINavigationBar Appearance() in init()

I was looking for this problem and found a great article about it . And i modified your code by this article and came to success. Here, how i solve this problem:

struct ContentView: View {
    
    init() {
        let coloredAppearance = UINavigationBarAppearance()
        
        // this overrides everything you have set up earlier.
        coloredAppearance.configureWithTransparentBackground()
        coloredAppearance.backgroundColor = .green
        coloredAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.black]
        
        // to make everything work normally
        UINavigationBar.appearance().standardAppearance = coloredAppearance
        UINavigationBar.appearance().scrollEdgeAppearance = coloredAppearance
    }
    
    var body: some View {
        NavigationView {
            List{
                ForEach(0..<15) { item in
                    HStack {
                        Text("Apple")
                            .font(.headline)
                            .fontWeight(.medium)
                            .lineLimit(1)

I hit this limitation in my independent Apple Watch app. Although this fix isn't strictly in SwiftUI, I went to the Interface.storyboard file, selected the hosting controller, selected the File inspector on the right, then set the color next to Global Tint under the Interface Builder Document section.

update for 13.4

note: revisiting this the next day, it may be possible that some of my issues were caused by my somewhat nonstandard setup: i am still running mojave, but have manually added the 13.4 support files (normally available only via xcode 11.4, which requires catalina). i mention this because i am/was also having some tab bar custom color issues, but i just noticed that those are only manifesting when i have the phone actually plugged in and am running the app from xcode. if i unplug, and just run the app normally, i am not seeing the tab bar issues, so it may be possible that the nav bar issue had some similarity ...

(i would add this as a comment on arsenius' answer (the currently accepted one) above, but i don't have the rep, so ...)

i was using that solution, and it was working perfectly up until 13.4, which seems to have broken it, at least for me. after a lot of view hierarchy tracing, it looks like they changed things such that the implicit UINavigationController is no longer easily accessible via the passed UIViewController as described in the workaround. it's still there though (pretty far up the tree), we just have to find it.

to that end, we can just walk the view hierarchy until we find the navbar, and then set the desired parameters on it, as usual. this necessitates a new discovery function, and some minor changes to the NavigationConfigurator struct, and its instantiation ...

first up, the discovery function:

func find_navbar(_ root: UIView?) -> UINavigationBar?
{
    guard root != nil else { return nil }

    var navbar: UINavigationBar? = nil
    for v in root!.subviews
    {   if type(of: v) == UINavigationBar.self { navbar = (v as! UINavigationBar); break }
        else { navbar = find_navbar(v); if navbar != nil { break } }
    }

    return navbar
}

modify the NavigationConfigurator as follows (note that we no longer care about passing in a view, since that's no longer reliable):

struct NavigationConfigurator: UIViewControllerRepresentable
{
    @EnvironmentObject var prefs: Prefs     // to pick up colorscheme changes

    var configure: () -> Void = {}
    func makeUIViewController(context: UIViewControllerRepresentableContext<NavigationConfigurator>) -> UIViewController { UIViewController() }
    func updateUIViewController(_ uiViewController: UIViewController, context: UIViewControllerRepresentableContext<NavigationConfigurator>) { self.configure() }
}

(in my app, i have a Prefs object which keeps track of colors, etc.)

... then, at the instantiation site, do something like this:

MyView()
    .navigationBarTitle("List", displayMode: .inline)
    .navigationBarItems(trailing: navbuttons)
    .background(NavigationConfigurator {
        if self.prefs.UI_COLORSCHEME != Colorscheme.system.rawValue
        {   if let navbar = find_navbar(root_vc?.view)
            {   navbar.barTintColor = Colors.uicolor(.navbar, .background)
                navbar.backgroundColor = .black
                navbar.titleTextAttributes = [.foregroundColor: Colors.uicolor(.navbar, .foreground)]
                navbar.tintColor = Colors.uicolor(.navbar, .foreground)
            }
        }
    })

note that i capture the root view controller elsewhere in my app, and use it here to pass to find_navbar(). you might want to do it differently, but i already have that variable around for other reasons ... there's some other stuff there specific to my app, eg, the color-related objects, but you get the idea.

WatchOS navigation title color using SwiftUI
Side note for watchOS is that you don't need to fiddle with the navigation color. It's the Watch Accent color you need to change. In your project go into WatchProjectName->Asset->Accent and change this

https://developer.apple.com/documentation/watchkit/setting_the_app_s_tint_color

Answer 20

Based on this https://stackoverflow.com/a/66050825/6808357 I created an extension where you can set the background color and the title color at the same time.

import SwiftUI

extension View {
    
    /// Sets background color and title color for UINavigationBar.
    @available(iOS 14, *)
    func navigationBar(backgroundColor: Color, titleColor: Color) -> some View {
        let appearance = UINavigationBarAppearance()
        appearance.configureWithTransparentBackground()
        appearance.backgroundColor = UIColor(backgroundColor)

        let uiTitleColor = UIColor(titleColor)
        appearance.largeTitleTextAttributes = [.foregroundColor: uiTitleColor]
        appearance.titleTextAttributes = [.foregroundColor: uiTitleColor]

        UINavigationBar.appearance().standardAppearance = appearance
        UINavigationBar.appearance().scrollEdgeAppearance = appearance
        
        return self
    }
}

Here's how to use it:

var body: some View {
    NavigationView {
        Text("Hello world!") // This could be any View (List, VStack, etc.)
        .navigationTitle("Your title here")
        .navigationBar(backgroundColor: .blue, titleColor: .white)
    }
}

Happy coding!

The new way to do it with UINavigationBarAppearance

extension UINavigationController {

    open override func viewDidLoad() {
        super.viewDidLoad()

        let standardAppearance = UINavigationBarAppearance()
        standardAppearance.backgroundColor = .blue
        standardAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
        standardAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
        navigationBar.standardAppearance = standardAppearance
        navigationBar.compactAppearance = standardAppearance
        navigationBar.scrollEdgeAppearance = standardAppearance

    }}

If you need separate styles for compactAppearance , scrollEdgeAppearance

extension UINavigationController {

open override func viewDidLoad() {
    super.viewDidLoad()

    let standardAppearance = UINavigationBarAppearance()
    standardAppearance.backgroundColor = .blue
    standardAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
    standardAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]


    let compactAppearance = UINavigationBarAppearance()
    compactAppearance.backgroundColor = .red


    let scrollEdgeAppearance = UINavigationBarAppearance()
    scrollEdgeAppearance.backgroundColor = .yellow


    navigationBar.standardAppearance = standardAppearance
    navigationBar.compactAppearance = compactAppearance
    navigationBar.scrollEdgeAppearance = scrollEdgeAppearance

}}

如果您不介意全局更改它，我发现进入资产目录并设置 AccentColor 有效。

Answer 23

The solution that worked for me was to use UINavigationBarAppearance() method, then add the .id() to the NavigationView. This will automatically redraw the component when the color changes.

Now you can have reactive color changes based on a state engine.

var body: some Scene {
  let color = someValue ? UIColor.systemBlue : UIColor.systemGray3

  let custom = UINavigationBarAppearance()
  custom.configureWithOpaqueBackground()
  custom.backgroundColor = color
  UINavigationBar.appearance().standardAppearance = custom
  UINavigationBar.appearance().scrollEdgeAppearance = custom
  UINavigationBar.appearance().compactAppearance = custom
  UINavigationBar.appearance().compactScrollEdgeAppearance = custom

  return WindowGroup {
    NavigationView {
      content
    }
      .id(color.description)
  }
}

Answer 24

This solution builds on the accepted answer that doesn't use any library nor does it apply UINavigationBarAppearance globally.

This solution fixes the issues that the accepted answer has (such as not working for the initial view or not working for large display mode) by adding a hack.

Note I would personally not use this hack in production code, nevertheless it's interesting to see that the issues can be worked around. Use at own risk.

struct NavigationHackView: View {

    @State private var isUsingHack = false

    var body: some View {
        NavigationView {
            List {
                NavigationLink {
                    Text("Detail view")
                        .navigationTitle("Detail view")
                        .navigationBarTitleDisplayMode(.inline)
                } label: {
                    Text("Show details view")
                }
            }
            .navigationTitle("Hack!")
            .background(
                NavigationConfigurator { navigationController in
                    // required for hack to work
                    _ = isUsingHack
                    navigationController.navigationBar.navigationBarColor(.red, titleColor: .white)
                }
            )
            .onAppear {
                // required for hack to work
                DispatchQueue.main.async {
                    isUsingHack.toggle()
                }
            }
            // required for hack to work, even though nothing is done
            .onChange(of: isUsingHack) { _ in }
        }
    }
}

struct NavigationConfigurator: UIViewControllerRepresentable {

    var configure: (UINavigationController) -> Void = { _ in }

    func makeUIViewController(
        context: UIViewControllerRepresentableContext<NavigationConfigurator>
    ) -> UIViewController {
        UIViewController()
    }

    func updateUIViewController(
        _ uiViewController: UIViewController,
        context: UIViewControllerRepresentableContext<NavigationConfigurator>
    ) {
        guard let navigationController = uiViewController.navigationController else {
            return
        }
        configure(navigationController)
    }
}

extension UINavigationBar {

    func navigationBarColor(
        _ backgroundColor: UIColor, 
        titleColor: UIColor? = nil
    ) {
        let appearance = UINavigationBarAppearance()
        appearance.configureWithOpaqueBackground()
        appearance.backgroundColor = backgroundColor

        if let titleColor = titleColor {
            appearance.titleTextAttributes = [.foregroundColor: titleColor]
            appearance.largeTitleTextAttributes = [.foregroundColor: titleColor]
            // back button appearance
            tintColor = titleColor
        }

        standardAppearance = appearance
        scrollEdgeAppearance = appearance
        compactAppearance = appearance

Post iOS 14 easy way to do:

        protocol CustomNavigationTitle: View {
            associatedtype SomeView: View
            func customNavigationTitle(_ string: String) -> Self.SomeView
        }
        
        extension CustomNavigationTitle {
            func customNavigationTitle(_ string: String) -> some View {
                toolbar {
                    ToolbarItem(placement: .principal) {
                        Text(string).foregroundColor(.red).font(.system(size: 18))
                    }
                }
            }
        }
        
        extension ZStack: CustomNavigationTitle {}
    
    Suppose your root view of view is made with ZStack
    it can be utilised below way
    
    ZStack {
    }. customNavigationTitle("Some title")

Answer 26

from iOS 14 , You can have any custom view you want (including custom text with custom color and font)

.navigationBarTitleDisplayMode(.inline)
.toolbar {
    ToolbarItem(placement: .principal) {
        VStack {
            Text("Yellow And Bold Title")
                .bold()
                .foregroundColor(.yellow)
        }
    }
}

Also you can set the navigation bar color from the iOS 16 like:

.toolbarBackground(.red, in: .navigationBar)

Answer 27

I have used ViewModifier to apply custom colour for navigation bar. I can't say below code modified actual navigation bar, but I find this work around better than above others.

Unlike UINavigationBar.appearance(), it is not applied to all view.

• Create a ViewModifer - I have use ShapeStyle , so you can apply any style to navigation bar. (like - gradient, colour)

struct NavigationBarStyle<S: ShapeStyle>: ViewModifier {
    private var bgStyle: S
    private var viewBackgroundColor: Color
    
    init(_ bgStyle: S, viewBackgroundColor: Color) {
        self. bgStyle = bgStyle
        self.viewBackgroundColor = viewBackgroundColor
    }
    
    func body(content: Content) -> some View {
        ZStack {
            Color(UIColor.systemBackground)
                .ignoresSafeArea(.all, edges: .bottom)
            
            content
        }
        .background(bgStyle)
    }
}

extension View {
    func navigationBarStyle<S: ShapeStyle>(_ bgStyle: S, viewBackgroundColor: Color = Color(UIColor.systemBackground)) -> some View {
        modifier(NavigationBarStyle(bgStyle, viewBackgroundColor: viewBackgroundColor))
    }
}

Note - you have to apply this modifier on the top most view to work. eg -

struct NewView: View {
    var body: some View {
        NavigationView {
            VStack {
                HStack {
                    Text("H Stack")
                }
                // .navigationBarStyle(Color.orange) not the right place
                Text("Hello World")
            }
            .navigationBarStyle(Color.orange) // right place to apply
        }
    }
}

Answer 28

struct ContentView: View {
    
    init() {
        UINavigationBar.appearance().largeTitleTextAttributes = [.foregroundColor: UIColor(Color("Golden"))]
     }
    
    var body: some View {
        NavigationView {
            List(movies) { movie in
                NavigationLink {
                    MovieDetail(movie: movie)
                } label: {
                    MovieCell(movie: movie)
                }
            }
            .navigationTitle("Movies")
        }
    }
}

Use UINavigationBar.appearance().largeTitleTextAttributes property for changing navigation bar title color

Answer 29

The simplest way I found was:

init() {
    UINavigationBar.appearance().tintColor = UIColor.systemBlue
    }

instead of the systemBlue you can use any other colors that you wish. You have to implement this outside the "var body: some View {}". you can also add:

@Environment(/.colorScheme) var colorScheme

on top of the init() and then you can use the .dark or .light to change the color the way you want in dark mode and light mode. example:

init() {
    UINavigationBar.appearance().tintColor = UIColor(colorScheme == .dark ? .white : Color(#colorLiteral(red: 0.2196078449, green: 0.007843137719, blue: 0.8549019694, alpha: 1)))
    }
