Can't use “Object” or “Objects” as entity in Core Data?

Question

I'm not sure, but I think I'm having problems with my project because one entity has the name "Object", tried to change this to "Objects", nothing changes. Maybe it's a reserved word?

Answer 1

According to this Object was an original root class for Objective-C which still exists somewhere in the class hierarchy so it wont be able to be used. I'm not sure about Objects but the obvious solution is to prefix your class names (which you should be doing anyway, but it's especially important for generic names like "Object")
