some View conform to UIView

[Skyline-23]

I use it with UIKit and preview
but when I use extension UIView preview, I got this error

Return type of instance method 'showPreview(width:height:)' requires that 'some View' conform to 'UIView'

This is my extension code

#if canImport(SwiftUI) && DEBUG
import SwiftUI
extension UIView {

    private struct Preview: UIViewRepresentable {
        let view: UIView

        func makeUIView(context: Context) -> UIView {
            return view
        }

        func updateUIView(_ uiView: UIView, context: Context) {
        }
    }

    func showPreview(width: CGFloat, height: CGFloat) -> some View {
        Preview(view: self).previewLayout(.fixed(width: width, height: height))      // error line
    }
}
#endif
