In SwiftUI, iOS15, 2nd level NavigationLink, isActive is not working

Question

in iOS15, it is not working:

import SwiftUI
struct ContentView: View {
    var body: some View {
        NavigationView {
            NavigationLink {
                Dest1().navigationTitle("Dest1")
            } label: {
                Text("to Destination 1")
            }
        }
    }
}

struct Dest1: View {
    @State var dest2Active: Bool = false
    var body: some View {
        NavigationLink(
            destination: Button {
                dest2Active = false // not working!!
            } label: {Text("dismiss")} .navigationTitle("Dest2"),
            isActive: $dest2Active
        ) {Text("to Destination 2")}
    }
}

The dismiss button in Dest2 is not working! I remember that in iOS14, this code works well. How to resolve this?

You need to add .navigationViewStyle(.stack) to make it work. Here is the test code that works for me.

import SwiftUI

@main
struct TestApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

struct ContentView: View {
    var body: some View {
        NavigationView {
            NavigationLink {
                Dest1().navigationTitle("Dest1")
            } label: {
                Text("to Destination 1")
            }
        }.navigationViewStyle(.stack) // <-- here the important bit
    }
}

struct Dest1: View {
    @State var dest2Active: Bool = false
    var body: some View {
        NavigationLink(
            destination: Button {
                dest2Active = false // now working!!
            } label: {Text("dismiss")} .navigationTitle("Dest2"),
            isActive: $dest2Active
        ) {Text("to Destination 2")}
    }
}
