How to select default font in a font picker?
The default font seems to be .AppleSystemUIFont based on UIFont.preferredFont(forTextStyle: .body).familyName. How can it be selected in a UIFontPickerViewController so that users can revert back to the original default font? import SwiftUI class FontPickerViewController: UIViewController, UIFontPickerViewControllerDelegate { var isPickerPresented: Binding<Bool>? var onFontPick: ((UIFontDescriptor) -> Void)? override func loadView() { super.loadView() let button = UIButton(type: .system) button.titleLabel?.font = UIFont.preferredFont(forTextStyle: .body) button.setTitle("Choose font", for: .normal) button.addTarget(self, action: #selector(showFontPicker), for: .touchUpInside) button.sizeToFit() button.backgroundColor = .clear view = button } func fontPickerViewControllerDidPickFont(_ viewController: UIFontPickerViewController) { dismiss(animated: true) isPickerPresented?.wrappedValue = false guard let fontDescriptor = viewController.selectedFontDescriptor else { return } onFontPick?(fontDescriptor) } func fontPickerViewControllerDidCancel(_ viewController: UIFontPickerViewController) { dismiss(animated: true) isPickerPresented?.wrappedValue = false } @objc func showFontPicker() { let configuration = UIFontPickerViewController.Configuration() configuration.includeFaces = true configuration.displayUsingSystemFont = false let fontPicker = UIFontPickerViewController(configuration: configuration) fontPicker.delegate = self present(fontPicker, animated: true) isPickerPresented?.wrappedValue = true } } struct FontPickerViewControllerRepresentable: UIViewControllerRepresentable { @Binding var isPickerPresented: Bool var onFontPick: (UIFontDescriptor) -> Void public func makeCoordinator() -> Coordinator { return Coordinator(self, onFontPick: self.onFontPick) } public class Coordinator { var parent: FontPickerViewControllerRepresentable let picker = FontPickerViewController() init(_ parent: FontPickerViewControllerRepresentable, onFontPick: @escaping (UIFontDescriptor) -> Void) { self.parent = parent picker.onFontPick = onFontPick picker.isPickerPresented = parent._isPickerPresented } } func makeUIViewController(context: Context) -> FontPickerViewController { context.coordinator.picker } func updateUIViewController(_ uiViewController: FontPickerViewController, context: Context) { if isPickerPresented { context.coordinator.picker.showFontPicker() } else { } } @available(iOS 16.0, *) func sizeThatFits(_ proposal: ProposedViewSize, uiViewController: FontPickerViewController, context: Context) -> CGSize? { uiViewController.view.intrinsicContentSize } } struct FontPicker: View { @State var isPickerPresented = false @State var selectedFont: UIFont? var font: Font? { if let selectedFont { return Font(selectedFont) } return nil } var body: some View { Button { isPickerPresented = true } label: { HStack { FontPickerViewControllerRepresentable(isPickerPresented: $isPickerPresented) { fontDescriptor in let size = UIFont.preferredFont(forTextStyle: .body).pointSize let font = UIFont(descriptor: fontDescriptor, size: size) selectedFont = font } Spacer() Text(selectedFont?.familyName ?? "Not Selected") .font(font) .foregroundColor(.secondary) } } .onAppear { print(UIFont.preferredFont(forTextStyle: .body)) } } } } struct Test3_Previews: PreviewProvider { static var previews: some View { Form { FontPicker() let defaultFont = UIFont.preferredFont(forTextStyle: .body) Text(defaultFont.familyName) Text(defaultFont.fontName) } } }

Multiple apps in webcredentials - Do the credentials need to work for each app?
I have a question regarding the "webcredentials" field in the "apple-app-site-association" file. If there are multiple apps listed in webcredentials, do the credentials for one app need to work for the other apps? I created an app without a web version and I am using the associated domain "webcredentials:website.com" to enable password autofill. I am wondering if I will be able to use the same associated domain for other apps in the future even if the credentials aren't shared between apps. (I tried using a subpath "webcredentials:website.com/app1", but the subpath isn't used when looking at Settings -&gt; Passwords) Thank you,
