Xcode 15.2 beta update: same issue as described above still exists.
Xcode 15.2 (final release) update: issue still exists. We treat all "warnings as errors", so this is frustrating. Our workaround now is to not upgrade to Sonoma (see note above)
Looks like Ventura 13.6.4 and Xcode 15.2.0 now generate these warnings.
Xcode 15.3.0 beta 2 does not resolve the warnings.
Curious if someone at Apple can help us understand if this is truly a Core Data regression. The warnings don't appear to affect runtime behavior, so we are left to believe it's not on the app side of things, and that the warnings will eventually go away.
Looks like this may be fixed with Sonoma 14.6.1.
All unexpected Core Data warnings are now gone:
Sonoma 14.6.1
Xcode 15.4.0 and Xcode 16 beta
Here's the Feedback ID: FB15428353
The report was posted on October 8. For now we have kept the test action enabled, which is burning through our paid Xcode Cloud hours. We are hoping the issue will be resolved soon, or we are given feedback on what to adjust in our workflow and/ or project settings.
