init?(string: String) returns an optional value. guard let url = URL(string: "https://...") else { return } let request = URLRequest(url: url) URLSession.shared.dataTask(with: request) or guard let url = URL(string: "https://...") else { return } do { let (data, _) = try await URLSession.shared.data(from: url) } catch { }

Reply to Help with Passkey Registration & Authentication on iOS 17 (Credential Provider + Error Code 1004)
I think Error Code 1004 suggests that you have entered your domain incorrectly somewhere. What is your associated domain, and what's the domain that you give to ASAuthorizationPlatformPublicKeyCredentialProvider(relyingPartyIdentifier: )? And what's the domain stated in your apple-app-site-association file? The domain has to be consistent in all these places.

Reply to Incorrect color for inline navigation bar title when dark mode AND reduce transparency ON.
You can customize the title text color and the background color of the navigation bar like the following for a workaround. import SwiftUI struct ContentView: View { @Environment(\.colorScheme) var colorScheme var body: some View { NavigationStack { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) } /* .navigationBarItems( trailing: Text("Trailing").foregroundStyle(.yellow) ) */ .navigationBarTitleDisplayMode(.inline) .toolbar { ToolbarItem(placement: .principal) { Text("GGGGGGG") .font(.title) .bold() .foregroundColor(colorScheme == .light ? .white : .black) } } .toolbarBackground(colorScheme == .light ? .black: .white, for: .navigationBar) .toolbarBackground(.visible, for: .navigationBar) } } }
