How do I interoperate with SwiftUI via UIHostingController and UIViewRepresentable in Swift?

In Swift, you can seamlessly bridge UIKit and SwiftUI using UIHostingController and UIViewRepresentable. This allows you to utilize SwiftUI views within your existing UIKit applications and vice versa. The UIHostingController is a UIKit view controller that manages a SwiftUI view, while UIViewRepresentable allows you to wrap a UIKit view for use in SwiftUI.

SwiftUI, UIHostingController, UIViewRepresentable, UIKit integration, Swift interoperability

This guide provides an overview of how to integrate SwiftUI into UIKit applications using UIHostingController and how to create reusable UIKit components in SwiftUI with UIViewRepresentable.


    // Example of using UIHostingController
    import SwiftUI
    import UIKit

    struct ContentView: View {
        var body: some View {
            Text("Hello from SwiftUI!")
        }
    }

    class HostingController: UIHostingController {
        required init?(coder aDecoder: NSCoder) {
            super.init(coder: aDecoder, rootView: ContentView())
        }
    }

    // Example of UIViewRepresentable
    struct MyCustomView: UIViewRepresentable {
        func makeUIView(context: Context) -> UIView {
            let view = UIView()
            view.backgroundColor = .red
            return view
        }

        func updateUIView(_ uiView: UIView, context: Context) {
            // Update the view as needed
        }
    }
