Ios 无法使用 NavigationView 和 NavigationLink 在 SwiftUI 中弹出当前屏幕

所以我在try 弹出当前屏幕时遇到了关于SwiftUI中的NavigationView和NavigationLinks的问题，在这种情况下不起作用.

我有3个屏幕A->B-&>C

每个屏幕都有一个弹出按钮.

来自B->A的POP正常，但当你从A->B-&>C导航时，来自C-&>B的POP不起作用.

你知道会有什么问题吗？我会附上下面的代码和一段视频. 该应用程序应该支持iOS 14.

struct ScreenA: View {
    @State private var showB = false
    
    var body: some View {
        NavigationView {
            VStack {
                Button("Go to B") {
                    showB = true
                }
                
                NavigationLink(destination: ScreenB(didTapGoBack: {
                    showB = false
                }), isActive: $showB) {
                    EmptyView()
                }
            }
        }
    }
}

struct ScreenB: View {
    var didTapGoBack: () -> Void
    @State var showC = false

    var body: some View {
        VStack {
            Button("Go to C") {
                showC = true
            }
        
            Button("Back to Screen A") {
                didTapGoBack()
            }
            
            NavigationLink(destination: ScreenC(didTapGoBack: {
                showC = false
            }), isActive: $showC) {
                EmptyView()
            }
        }
    }
}

struct ScreenC: View {
    var didTapGoBack: () -> Void
    
    var body: some View {
        VStack {
            Text("Screen C")
            Button("Back to Screen B") {
                didTapGoBack()
            }
        }
    }
}

@main
struct TestNavApp: App {
    var body: some Scene {
        WindowGroup {
            ScreenA()
        }
    }
}
