I'm unable to run a widget containing a live activity with the error message at the bottom of this post. I've verified I have NSSupportsLiveActivities set to yes in the correct Info.plist, and have downloaded sample projects from github containing the same values. This error occurs while running on a device or simulator, on Xcode 15 and 16, iOS simulator 17 and 18.

  1. Create sample project
  2. Create new widget extension target
  3. Set NSSupportsLiveActivities to true in the appropriateinfo.plist
  4. Run the widget

This seems to be a longstanding issue https://forums.developer.apple.com/forums/thread/651611

Any ideas for debugigng? I'm completely blocked from running live activities.

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.
