在swiftui中2秒后推送视图

Question

如何在没有任何交互的情况下在 swiftUI 中 x 秒后推送视图？

 NavigationView{
            .onAppear {
                DispatchQueue.main.asyncAfter(deadline: .now()+1.0) {
                    NavigationLink(destination: pageViewUi()) {
                        EmptyView()
                    }
                }
            }
}

你可以这样处理：

struct ContentView: View {
    @State var show = false
    var body: some View {
        NavigationView{
            NavigationLink(destination: Text("OK"), isActive: $show, label: {
                EmptyView()
            })
                .onAppear {
                    DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) {
                        self.show.toggle()
                    }
            }
        }
    }
}
