The following sample code doesn't work as expected. In addition, the behavior differs between iOS 16.0 and iOS 16.1 beta.

If there is a workaround, please let me know. (I know that navigationDestination(isPresent:destination:) can be substituted in iOS 16.0, but it doesn't work in iOS 16.1 beta)

I reported this issue (FB11599516).


@main

struct StackViewSampleApp: App {
    var body: some Scene {
        WindowGroup {
            NavigationStack {
                ContentView()
            }
        }
    }
}

struct ContentView: View {

    var body: some View {
        VStack {
            NavigationLink("SubView") {
                SubView()
            }
        }
        .navigationDestination(for: Int.self) { v in
            DetailView(value: v)
        }
    }
}

struct SubView: View {
    var body: some View {
        NavigationLink(value: 1) {
            Text("DetailView")
        }
        .navigationTitle("SubView")
    }
}

struct DetailView: View {
    let value: Int
    var body: some View {
        Text("\(value)")
            .navigationTitle("Detail")
    }
}

Actual behavior

iOS 16.0 behavior / Xcode Version 14.0 (14A309)

Pressing "SubView" button in RootView, it goes to SubView.
Pressing "DetailView" button in SubView, it goes to DetailView.
Pressing "Back" button, it goes to RootView. (Expect: it goes to SubView)

iOS 16.1 beta(20B5045d) / Xcode Version 14.1 beta 2 (14B5024i)

Pressing "SubView" button in RootView, it goes to SubView.
Pressing "DetailView" button in SubView, it goes to SubView.
Pressing "DetailView" button in SubView, it goes to SubView. (Repeat) (Expect: it goes to DetailView)
Pressing "Back" button in SubView, it goes to DetailView. (Expect: it goes to a previous view)

I created a ViewModifier to work around this problem.

If you are not using NavigationPath, NavigationDestinationSelectedViewModifier may be available.

https://github.com/hmuronaka/NavigationDestinationSelectedViewModifier

Example


struct ContentView: View {
    var body: some View {
        NavigationLink("SubView") {
            SubView()
        }
    }
}

struct SubView: View {
    @State private var selection: Int?

    var body: some View {
        List(selection: $selection) {
            ForEach(0...10, id: \.self) { idx in
                NavigationLink(value: idx) {
                    Text("Detail \(idx)")
                }
            }
        }
        .navigationDestination(selected: $selection, destination: { value in
            DetailView(value: value)
        })
    }
}

struct DetailView: View {
    let value: Int
    var body: some View {
        Text("\(value)")
            .navigationTitle("Detail")
    }
}
