如何在SwiftUI中隐藏特定屏幕上的导航栏？

struct HideNavigationBar: ViewModifier {
    func body(content: Content) -> some View {
        content
            .navigationBarHidden(true)
    }
}

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                Text("Hello, World!")
            }
            .modifier(HideNavigationBar())
        }
    }
}

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                Text("Hello, World!")
            }
            .navigationBarTitle("")
            .navigationBarHidden(true)
        }
    }
}
