Hi everyone,
Have anybody faced with Core Data issues, trying to migrate the project to Xcode16 beta 4?
We are using transformableAttributeType in some entities, with attributeValueClassName = "[String]" and valueTransformerName = "NSSecureUnarchiveFromData". It is working just fine for years, but now I am trying to run the project from Xcode16 and have 2 issues:
in Xcode logs I see warning and error:
CoreData: fault: Declared Objective-C type "[String]" for attribute named alertBarChannels is not valid
CoreData: Declared Objective-C type "[String]" for attribute named alertBarChannels is not valid
periodically the app crashes when we are assigning value to this attribute, with error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFConstantString characterAtIndex:]: Range or index out of bounds'
Once again, in Xcode 15 it works fine, and it was working for years.
Cannot find any information about what was changed in the framework...
Thank you in advance for any information, which could clarify what is going on.
