I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times:
'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release
This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData.
My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).
