Hello … I love the generation capability from Xcode. I generated the Swift models using that, ran into the problem. Tried a few things manually, went back to generated fresh SwiftData models. I also have generated the Core Data classes, and compared that manually to the SwiftData versions.

Also had this issue, no grey images. I went through and deleted all the localization images that i added and then added them back. I was able to submit after that.

Will do. Thanks FB11518279 (Xcode crashes when updating existing watch app and extension to a single-target watch app)
