是否可以在同一个视图 SwiftUIView 和 UIViewControllerRepresentable 中组合在一起？

Question

我想知道是否可以在同一个视图中合并 View 和 UIViewControllerRepresentable。我试过了：

//Here I declare MyViewController:
class MyViewController: UIViewController {
    override viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .red
    }
}

struct MyViewControllerIntegrate: UIViewControllerRepresentable {

    func makeUIViewController(context: UIViewControllerRepresentableContext<MyViewControllerIntegrate>) -> MyViewController {
        return MyViewController()
    }

    func updateUIViewController(_ uiViewController: MyViewController, context: UIViewControllerRepresentableContext<MyViewControllerIntegrate>) {
    }
}

struct MyView: View {
    var body: some View {
        Text("Hello Whosebug!")
    }
}

struct ContentView: View {
    var body: some View {
        MyView()
        MyViewController()
        .frame(height: 400)
    }
}

Xcode 显示一条错误消息：

Function declares an opaque return type, but has no return statements in its body from which to infer an underlying type

有什么提示吗？谢谢

将它们放在组中（或某些堆栈中，例如 VStack）

struct ContentView: View {
    var body: some View {
        Group {
           MyView()
           MyViewController()
              .frame(height: 400)
        }
    }
}
