I will try that and let you know how it goes.

Works like a champ on my test app. Perhaps my real app is so old that the configuration is messed up somewhere in there.

Any help? I've spent a few hours now comparing the two apps, changing entitlement files, etc. I'm also using Cursor with premium calls to debug this, and having 0 luck.

I tried the entitlements file thing. I’ll try the other stuff and get back at you. This really should not be so difficult. That said, thanks for helping.

I fired up Xcode to try and get this working, and just on a whim decided to try one more time to see if magic occurred while I was asleep. In fact, it did! Somehow the weatherkit now works on my simulator. On to check it on testflight. @The app crashes every single are you working now? Perhaps Apple reset something on their end?
