Swift: How to integrate UIView and UIViewController to SwiftUI View

1. Integrate UIView to SwiftUI View:

class UIViewExample: UIView {

}

struct SwiftView: UIViewRepresentable {

// update方法使我们能够将UIView和SwiftUI状态更新保持同步

func updateUIView(_ uiView: UIViewExample, context: Context) {

}

// make方法返回初始视图

func makeUIView(context: Context) -> UIViewExample {

}

}

2. Integrate UIViewController to SwiftUI View:

class UIViewControllerExample: UIViewController {

}

struct SwiftView : UIViewControllerRepresentable {

// Init your ViewController

func makeUIViewController(context: Context) -> some

    UIViewController {

let controller = UIViewControllerExample()

return controller

}

// No idea what to do here

func updateUIViewController(_ uiViewController:

    UIViewControllerType, context: Context) {

}

}
