Sharing UserDefaults between main app and Widget in iOS 14

Question

I am writing a widget for iOS, seems UserDefaults is not accessible in the widget, I added app group as following, still it's nil:

let prefs = UserDefaults(suiteName:"group.myco.myapp")

Still when I try to read something from prefs which I set in the main app, it's nil here.

You'll need to add the AppGroup capability to the widget target. Select the project, then select the widget target, go to the Signing & Capabilities tab, and click the + Capability button. Then choose AppGroup and configure it with your group.
