在SwiftUI Apple Watch应用中实现基于页面的导航

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {
            List {
                NavigationLink(destination: DetailView(text: "Page 1")) {
                    Text("Page 1")
                }
                NavigationLink(destination: DetailView(text: "Page 2")) {
                    Text("Page 2")
                }
            }
            .navigationTitle("Navigation")
        }
    }
}

struct DetailView: View {
    var text: String
    
    var body: some View {
        VStack {
            Text(text)
                .font(.title)
            NavigationLink(destination: nil) {
                Text("Back")
            }
        }
    }
}

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