导航链接/视图对于分层导航是有意义的--这感觉像是模态的东西。你可以用链接来实现，但是像这样的东西感觉更好：

import SwiftUI

struct TutorialView: View {
    
    @Binding var shouldShowTutorial: Bool
    
    var body: some View {
        VStack {
            Text("Tutorial...")
            Button("Done") {
                shouldShowTutorial = false
            }
        }
    }
    
}

struct AppRootView: View {
    
    var body: some View {
        Text("App View")
    }
    
}

struct ContentView: View {
    
    @AppStorage("shouldShowTutorial") var shouldShowTutorial = true
    
    var body: some View {
        AppRootView()
            .fullScreenCover(isPresented: $shouldShowTutorial) {
                TutorialView(shouldShowTutorial: $shouldShowTutorial)
            }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

如果你设置使用导航链接，我也可以提供一个例子。
