如何在SwiftUI中为所有类型的设备隐藏NavigationBar？

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
                .navigationBarHidden(true)
        }
    }
}

struct ContentView: View {
    var body: some View {
        NavigationView {
            // 视图内容
        }
        .navigationBarHidden(true)
    }
}
