The error
The widget background view is missing. Please ensure that you have called the `containerBackground(for: .widget) {…}` modifier in your widget view.
I do use .containerBackground(Color.blue.gradient, for: .widget), but it's no longer working in Xocde beta 8
The issue is due to this error message

Hower I can see the background in SwiftUI preview.
This was caused by running watchOS extension target instead of the app target. I don't really need to debug widgets because the code is so simple, but if you have this issue, just run the app target for now. I also opened a radar FB13141297.
I have managed to fix this warning by providing the background for all families.
var body: some View {
switch family {
case ...
// Return your custom widget here for families you support
default:
// Fallback for not supported families
Image(systemName: "xmark.circle")
.containerBackground(Color.black, for: .widget)
}
}
