我如何从 UIAlertController 导航到新屏幕（swiftUI）

Question

how can I navigate from UIAlertController(UIKit) to a new view(SwiftUi) due the the reason the swiftui alert can't use a textfield I used UIKit(UIalertcontroller) and I want to open a new screen after I click the submit button

I have tried:

    var passwordField: UITextField? = nil

    let alert = UIAlertController(title: "Admin Passcode", message: "Please enter an administrator password", preferredStyle: .alert)

    alert.addAction(UIAlertAction(title: "Submit", style: .default, handler: { Action in
        if let passwordField = passwordField {
            if passwordField.text == Constants.AdminPwd {
                print("Wow😁")
                DeviceConfigurationView(activeView: true)
            } else {
             let alert2 = UIAlertController(title: "Bad Password", message:            "Incorrect password", preferredStyle: .alert)
                alert2.addAction(UIAlertAction(title: "Dismiss", style: .default, handler: nil))
                rootContoller().present(alert2, animated: true, completion: nil)
            }
        }
    }))

    alert.addAction(UIAlertAction(title: "Cancel", style: .default) {
        action in
        alert.dismiss(animated: true)
    })

    alert.addTextField {
        (textField) in

        textField.placeholder = "Password"
        textField.isSecureTextEntry = true
        textField.becomeFirstResponder()
        passwordField = textField

    }
    rootContoller().present(alert, animated: true, completion: nil)
    
    func rootContoller()->UIViewController{
    guard let  screen = UIApplication.shared.connectedScenes.first as? UIWindowScene                            else {
        return .init()
    }
    
    guard let root = screen.windows.first?.rootViewController else {
        return .init()
    }
    return root
        }
    }

this is the view I want to navigate to:

import UIKit

struct DeviceConfigurationView: View {
    
    @State var activeView: Bool 
    
    var body: some View {
        NavigationView {
            DeviceView()
        }
        .navigationViewStyle(.stack)
    }
}




struct DeviceView: View {
    
    @Environment(\.presentationMode) var presentationMode
    

    
    @State var  ToggleIsOn: Bool = false
    @State  var isExpandAudioSampleRate: Bool = false
    @State  var isExpandVideoResolution: Bool = false
    @State  var isExpandVideoResolutionForLocalVideoFile: Bool = false
    @State private var textField: String = ""
  
    var body: some View  {
            List {
                
                // Device
                Section(header:Text("Device"),
                        footer:
                            HStack {
                    Text("Device ID")
                    TextField("Device id", text: $textField)
                }) {
                    
                }
                
                // offline
                Section {
                    Toggle(isOn: $ToggleIsOn) {
                        Text("Offline Mode")
                            .opacity(5)
                    }
                    
                } header: {
                    Text("Offline")
                }

                Section {

and I am getting this error my error

From your code logic, it seems to be like

if passwordField.text == Constants.AdminPwd {
    print("Wow😁")
    let controller = UIHostingController(rootView: DeviceConfigurationView(activeView: true))
    rootContoller().present(controller, animated: true, completion: nil)
} else {
    ...
}
