Create previews to use in UIKit

UIKitPreviews.swift

struct MyViewControllerClass_Previews: PreviewProvider {
    static var previews: some View {
        UIViewControllerPreview {
            return MyViewControllerClass()
        }
        .previewDevice("iPhone SE (2nd generation)")
    }
}


import SwiftUI

@available(iOS 13, *)
struct UIViewControllerPreview<ViewController: UIViewController>: UIViewControllerRepresentable {
    let viewController: ViewController

    init(_ builder: @escaping () -> ViewController) {
        viewController = builder()
    }

    func makeUIViewController(context: Context) -> ViewController { viewController }

    func updateUIViewController(_ uiViewController: ViewController, context: Context) {}
}
