I have a view in swift(UIKit). I have converted this view to UIViewRepresentable and this I have used in swiftUI and my UIKIt view is visible in it.

Code Block swiftimport SwiftUI
struct ContentView: View {
    var body: some View {
        VStack {
            Text("Hello, world!").padding()
            Text("This is root content view")
						MyViewRepresentable()
        }
    }
}

This above swiftUI contentView is working fine while showing in the application form. But when I try the same in Widgets, the application is getting crashed.

I am getting the following error :
Fatal error: PlatformViewRepresentableAdaptor<MyViewRepresentable>: file /Library/Caches/com.apple.xbs/Sources/ChronoSim/Chrono-63.5/WidgetKit/SPI/WidgetViewArchive.swift, line 254

That's correct, WidgetKit does not support embedding UIKit views.

In this thread, Apple's Engineer says

UIKit views wrapped in UIViewRepresentable will not work in WidgetKit.

He/she says they will appear blank, but may be related to your issue.
