I recently built a widget with WidgetKit. When I bulding app from Xcode on the simulator widget appears, but when I install app from TestFlight widget is missing. Does anyone know what might have happened to widgets in iOS 18 that could cause this issue? By the way, it works for me in the Simulator but not on a real device.
The best first course of action here would be to use Console.app to monitor to the relevant processes related to your app and extensions.
A good way to start would be with filtering by the BundleID of the target and / or the target name itself (the process name).
Also be sure to check the system processes for additional information. This will vary based on what and where you are looking but some examples:
To debug APNS you'll want to monitor apd along with other relevant processes.
To debug WidgetKit, LiveActivities, Dynamic Island you'll want to monitor springboardd, liveactivitiesd along with other relevant processes.
