Core data: Unable to load class named "CDAccount"

Question

I've recently downloaded iOS 8 to make sure that my existing app works properly with it, but I'm getting a warning in the debugger on launch:

"CoreData: warning: Unable to load class named 'CDAccount' for entity 'CDAccount'.  
Class not found, using default NSManagedObject instead."

After some research, it seems like people have had similar issues when using Core Data in Swift, but all my code is in Objective-C (and the data model hasn't changed for at least 6 months).

Any advice is much appreciated, I'm really nervous that my app isn't going to function properly once people start upgrading to iOS 8!

Answer 1

I had the exact same problem in Objective-C and Xcode 6. For some reason, Xcode had removed my 'CustomNSManagedObject'.m classes from my Compile Sources.

Go to your project target -> Build Phases -> Compile Sources and use the + button to add CDAccount.m

If you are using Mogenerator to create a _CDAccount.m file, add that to your Compile Sources as well.

Answer 2

Remove the "dot" in Configurations "Default" on .xcdatamodeld:

Rebuild the application.

Answer 3

My issue was also similar, but the reason was that module of entity was not set.
