Hello
I am adding core data to an existing project that doesn't currently have it. I created the Data Model and added one entity with attributes. When I right click on "Editor/Create NSManagedObject Subclass" it creates 4 files - EntityName+CoreDataClass.h, .m and EntityName+CoreDataProperties.h and .m. The build fails with an error "2 duplicate symbols for architecture x86_64. I can build without subclassing the entity.
Can someone please help! I have spent many hours trying to figure this out.
duplicate symbol _OBJC_CLASS_$_CDEntityName in:
