What is UIViewControllerRepresentable ?

 UIViewControllerRepresentable

Instance to create and manage UIViewController object in our SwiftUI interface. 

Create UIViewControllerRepresentable 

• func makeUIViewController(context: Context) -> UIViewController 

Update UIViewControllerRepresentable 

• func updateUIViewController(_ uiViewController: UIViewController, context: Context){

Specifying Size

• func sizeThatFits(_: ProposedViewSize, uiViewController: Self.UIViewControllerType, context: Self.Context) -> CGSize?

To provide a custom Co-ordinator Object

• func makeCoordinator() -> Self.Coordinator

Similarly, we have UIViewRepresentable to manage UIViews.
