I am writing a configurable widget for Big Sur under XCode 12.0 beta 5. There's no Intent Configuration available for macOS target. Do I miss something or the functionality hasn't been added? Currently using Xcode 12 beta 6 still not able to configure widget for macOS. Any update for this or any workaround? And suppose if the user choose an option. What's the best way to save the option? You can pass default value in your (*IntentHandling) Protocol. There is optional method available for custom model in (*IntentHandling) Protocol.

Looking for the same, any solution?
