Hello I have reported an issue on the Feedback Assistant with more information and attachments, FB number is: FB16421665 I have tried to use preview but it failed with: Failed to build the scheme “MyWidgetExtension” thanks

Yeah, see my solution in the newest answer

Yeah: add @ViewBuilder before func resolve this issue

Yeah, my solution: var body: some View { …. { } .adoptableWidgetBackground(color) } extension View { func adoptableWidgetBackground(_ color: Color) -> some View { if #available(iOS 17.0, *) { containerBackground(for: .widget) { color } } else { background(color) } } }

Thank you, this is very helpful
