I’m encountering an issue with SwiftUI navigation in iOS 18, where navigating to a DetailView causes unexpected duplication of navigation behavior when @Environment(.dismiss) is used. Code Example: Here’s a simplified version of the code: struct ContentView: View { var body: some View { NavigationStack { NavigationLink("Go to Detail View", destination: DetailView()) .padding() } } } struct DetailView: View { @Environment(\.dismiss) var dismiss var body: some View { VStack { let _ = print("DetailView") // This print statement is triggered twice in iOS 18 } } } Issue: In iOS 18, when @Environment(.dismiss) is used in DetailView, the print("DetailView") statement is triggered twice. The same code works correctly in iOS 17 and earlier, where the print statement is only triggered once, as expected. However, when I remove @Environment(.dismiss) from DetailView, the code works as intended in iOS 18, with the print statement being triggered only once and no duplication of navigation behavior. Alternative Approach with .navigationDestination(for:): I also tested using .navigationDestination(for:) to handle navigation: struct ContentView: View { var body: some View { NavigationStack { NavigationLink("Go to Detail View", destination: DetailView()) .padding() } } } struct DetailView: View { @Environment(\.dismiss) var dismiss var body: some View { VStack { let _ = print("DetailView") // This print statement is triggered twice in iOS 18 } } } Even with this alternative approach, the issue persists in iOS 18, where the print statement is triggered twice. What I've Tried: I’ve confirmed that removing @Environment(.dismiss) solves the issue, and the print statement is triggered only once, and the navigation works as expected in iOS 18 without duplication. The issue only occurs when @Environment(.dismiss) is in use, which seems to be tied to the navigation stack behavior. The code works correctly in iOS 17 and below, where the print statement is only called once. Expected Behavior: I expect the print("DetailView") statement to be called once when navigating to DetailView, and that the navigation happens only once without duplication. The presence of @Environment(.dismiss) should not cause the navigation to be triggered multiple times. Questions: Is this a known issue with iOS 18 and SwiftUI navigation? Specifically, is there a new behavior that interacts differently with @Environment(.dismiss)? Has anyone else encountered this problem, and if so, what’s the recommended way to handle it in iOS 18? Is there a workaround to ensure that the navigation doesn’t trigger more than once when using @Environment(.dismiss) in iOS 18? Any help or insights would be greatly appreciated!
