How can add custom fonts and images to my picker?

Question

I have a picker in my app that displays the currently picked option as its label. However, I can't seem to figure out how to change the font used by the picker for its label and for displaying all the picker options. I would also like to put an icon in front of the text of the picker that's part of the picker button but doesn't change as the text does so that a user could click both the text and the icon for the picker to appear.

Here's the code I am using for my picker:

var fylker = ["Norge", "Akershus", "Agder", "Buskerud", "Finnmark", "Innlandet", "Møre og Romsdal", "Nordland", "Oslo", "Østfold", "Rogaland", "Troms", "Trøndelag", "Vestfold og Telemark", "Vestland"]

Picker("Fylke", selection: $selectedFylke) {
                            ForEach(fylker, id: \.self) {
                                Text($0)
                            }
                        }

I've already tried things like:

Picker("Fylke", selection: $selectedFylke) {
                            ForEach(fylker, id: \.self) {
                                Text($0).font(.custom("Custom-Bold", size: 34))
                            }
                        }

and

Picker("Fylke", selection: $selectedFylke) {
                            ForEach(fylker, id: \.self) {
                                HStack {
                                Image(systemName: "chevron.forward.circle")
                                Text($0)
                                }
                            }
                        }

to no avail

Any ideas? Thanks!

Answer 1

from what i understand i think you could try to use a font modifier to add your custom font and add image inside HStack so they are beside each other like that

import SwiftUI

struct SwiftUIView: View {
var fylker = ["Norge", "Akershus", "Agder", "Buskerud", "Finnmark", 
 "Innlandet", "Møre og Romsdal", "Nordland", "Oslo", "Østfold", 
 "Rogaland", "Troms", "Trøndelag", "Vestfold og Telemark", "Vestland"]
@State var selectedFylke:String = ""

var body: some View {
    Picker("Fylke", selection: $selectedFylke) {
        ForEach(fylker, id: \.self) { I in
            HStack(){
                Text(I).font(Font.custom("Font-Family-Name", size: 16))
                Image(systemName: "pencil")
            }.tag(I)
        }
    }.frame(width: 200, height: 60, alignment:.center).background(Color.red)
    
}
}

  struct SwiftUIView_Previews: PreviewProvider {
    static var previews: some View {
        SwiftUIView()
    }
    }

also if you mean to add the image beside the picker so they seemed as a button picker you can do that

import SwiftUI

struct SwiftUIView: View {
var fylker = ["Norge", "Akershus", "Agder", "Buskerud", "Finnmark", 
 "Innlandet", "Møre og Romsdal", "Nordland", "Oslo", "Østfold", 
  "Rogaland", "Troms", "Trøndelag", "Vestfold og Telemark", "Vestland"]
   @State var selectedFylke:String = ""

 var body: some View {
    HStack(){
    Image(systemName: "pencil").foregroundColor(.white)
    Picker("search", selection: $selectedFylke) {
        ForEach(fylker, id: \.self) {
                Text($0).font(Font.custom("Font-Family-Name", size: 16))
        }
    }
    }.frame(width: 200, height: 60, alignment: 
     .center).background(Color.red).background(Color.red).cornerRadius(30)
   }
 }

struct SwiftUIView_Previews: PreviewProvider {
static var previews: some View {
    SwiftUIView()
   }
 }

try this approach to set the font used by the Picker :

struct ContentView: View {

    let fylker = ["Norge", "Akershus", "Agder", "Buskerud", "Finnmark",
                  "Innlandet", "Møre og Romsdal", "Nordland", "Oslo", "Østfold",
                  "Rogaland", "Troms", "Trøndelag", "Vestfold og Telemark", "Vestland"]
    
    @State var selectedFylke = ""
    
    var body: some View {
        Picker("Fylke", selection: $selectedFylke) {
            ForEach(fylker, id: \.self) { item in
                HStack {
                    Image(systemName: "chevron.forward.circle")
                    Text(item)
                }
                .font(.custom("Custom-Bold", size: 34)) // for both the Text and the Image
                .tag(item)
            }
        }.pickerStyle(.wheel) // <-- here
    }
}

This does not work with pickerStyle: automatic , menu and segmented
