Ok that's why CoffeeGame sample crashes and not FoundationModelsTripPlanner. because only coffee game is using Transcript!

Ok thanks FB17970083 I experience the same problem with Apple latest Sample projects like "Petite asteroid" so it's not caused by my scenes.

ok, so I'm starting to make migration to Core Data but I have issues with @FetchRequest not updating when syncing from CloudKit Have you also seen issues? The thing I'm trying to do at the moment is keeping both Core Data and Swift Data stack. It seems to be supported in the apple documentation (for migration for exemple).

ok opened FB13098242 on this.

Ok, received all invitations about 48h later...

I also have the same issue. I can't open any app project from Swift Playgrounds 4 on Mac (I have m1 pro Mac so it's not an intel issue). I tried updating to Monterey 12.2 beta but I still have the same issue
