Basic SwiftUI picker was working fine. Updated to Xcode 13. It is no longer using wheel as default style. Manually setting picker style fixes it.
Why did the style change?
Is there a way to set the default style app wide?
Why did this change at all since we did NOT change the target version of iOS nor the build iOS version.
struct MyView: View {
var arrayOfNames = ["Tom", "Nick", "Tony", "Dylan"]
@State private var selectedIndex = 0
var body: some View {
Picker("Names", selection: $selectedIndex) {
ForEach(0 ..< arrayOfNames.count) {
Text(self.arrayOfNames[$0])
}
}.pickerStyle(.wheel)
}
}
Code in our app that has not been modified now looks broken.

I have a SwiftUI NavigationView and a SwiftUI view displayed in SwiftUI. The navigation link refers to a UIViewControllerRepresentable wrapping a UIViewController. I have been unable to remove the back button title, nor have I been able to set the tint of the back button when navigating to this UIKit view controller. This is targeting iOS 15.
Here's a minimal application that attempts it. I had similar issue just setting the Title for the UIKit view controller, but found reference to the SwiftUI modifier on the NavigationLink. I haven't found other modifiers for tint nor removing back button title.
I've also seen references that this needs to be done after the view controller moves to a wrapper parent controller that SwiftUI creates during this process. I've tried putting it in viewWillAppear, viewDidAppear, init(), didMove(toParent:, willMove(toParent. These work for setting the title but not for setting the tint nor removing back button text.
I've tried setting backButtonDisplayMode = .minimal in a bunch of places with confusing results.
import SwiftUI
import UIKit
struct ContentView: View {
init() {
UIBarButtonItem.appearance().tintColor = .systemPink
}
var body: some View {
NavigationView {
VStack {
NavigationLink(destination: MyViewControllerRepresentable()
.navigationTitle("TitleFromSwiftUI")) {
Text("MyVC")
}
Spacer()
}
.navigationTitle("Top")
.navigationBarTitleDisplayMode(.inline)
}
}
}
struct MyViewControllerRepresentable: UIViewControllerRepresentable {
func makeUIViewController(context: Context) -> MyViewController {
return MyViewController()
}
func updateUIViewController(_ uiViewController: MyViewController, context: Context) {}
}
class MyViewController : UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .white
title = "Nested view" // Doesn't work when pushed from SwiftUI view
navigationItem.backButtonDisplayMode = .minimal // Only works for nested views
navigationItem.backBarButtonItem?.tintColor = .systemPink // Never works
let button = UIButton(primaryAction: UIAction { _ in
self.navigationController?.pushViewController(MyViewController(), animated: true)
})
button.frame = CGRect(x: 100, y: 150, width: 200, height: 20)
button.setTitle("Button", for: .normal)
view.addSubview(button)
}
}
