如何在不同的视图中使用SwiftUI？

NavigationView {
    List {
        NavigationLink(destination: DetailView()) {
            Text("Go to Detail View")
        }
    }
}

TabView {
    Text("Tab 1")
        .tabItem {
            Image(systemName: "1.circle")
            Text("Tab 1")
        }
    Text("Tab 2")
        .tabItem {
            Image(systemName: "2.circle")
            Text("Tab 2")
        }
}

struct ContentView: View {
    @State private var isShowingSheet = false
    
    var body: some View {
        Button("Show Sheet") {
            isShowingSheet = true
        }
        .sheet(isPresented: $isShowingSheet) {
            SheetView()
        }
    }
}

struct ContentView: View {
    @State private var isShowingView1 = true
    
    var body: some View {
        ZStack {
            if isShowingView1 {
                View1()
            } else {
                View2()
            }
        }
    }
}
