Why does attempting to utilize my UIViewController from UIkit in SwiftUI result in failure to confirm to the representable protocol?

edit

This is because UIViewController and SwiftUI's View protocol are two different things and cannot be used interchangeably. In order to use a UIViewController in SwiftUI, you need to create a wrapper around it that confirms to the Representable protocol. The Representable protocol is used to bridge the gap between the two frameworks and provide a way for SwiftUI to communicate with UIKit.

To create a wrapper, you can create a new struct or class that conforms to the UIViewControllerRepresentable protocol. This protocol requires you to implement two methods:

1. A makeUIViewController method that creates and returns an instance of your UIViewController
2. A updateUIViewController method that updates the view with new data or changes

Once you've created your wrapper, you can then use it in your SwiftUI view just like any other View.

Here's an example implementation:

struct MyUIViewControllerWrapper: UIViewControllerRepresentable {
    typealias UIViewControllerType = MyUIViewController

    func makeUIViewController(context: UIViewControllerRepresentableContext<MyUIViewControllerWrapper>) -> MyUIViewController {
        return MyUIViewController()
    }

    func updateUIViewController(_ uiViewController: MyUIViewController, context: UIViewControllerRepresentableContext<MyUIViewControllerWrapper>) {
        // Update the view controller here
    }
}

struct MySwiftUIView: View {
    var body: some View {
        MyUIViewControllerWrapper()
    }
}

In this example, we've created a wrapper called MyUIViewControllerWrapper that conforms to the UIViewControllerRepresentable protocol. The makeUIViewController method creates and returns an instance of our custom UIViewController, while the updateUIViewController method is used to update the view with any new data or changes. In our SwiftUI view, we can use our wrapper just like any other View.
