NSManagedObject subclasses duplicate declaration

So, when my data model is ready, I tried to generate the subclasses when my data model file is open:

Editor -> Create NSManaged Object Subclasses

Okay, two files are generated, one is class declaration, the other is the property.

However, I was immediately prompted that I did a redeclaration of a class that already exists. This is where the original generated files are: previously generated files

My question is obvious:

  1. When were those two files generated?
  2. What to do if I want those files in my project navigator, and, of course, the same folder as my ViewController?
Solution

  • You are generating files which have already been generated for you by Xcode and thus get duplicate declarations.
