如何在SwiftUI中通过函数调用直接切换视图？

struct ContentView: View {
    var body: some View {
        VStack {
            Text("当前视图")
            Button(action: {
                switchView()
            }) {
                Text("切换到另一个视图")
            }
        }
    }
    
    func switchView() {
        let newView = OtherView()
        UIApplication.shared.windows.first?.rootViewController = UIHostingController(rootView: newView)
    }
}

struct OtherView: View {
    var body: some View {
        VStack {
            Text("另一个视图")
            Button(action: {
                switchView()
            }) {
                Text("切换回当前视图")
            }
        }
    }
    
    func switchView() {
        let newView = ContentView()
        UIApplication.shared.windows.first?.rootViewController = UIHostingController(rootView: newView)
    }
}
