title: Invalid redeclaration on CoreData classes
body: <p>I am working with CoreData, on an entity called "RoleName".</p>
  
  <p>The problem is: I click on "Create NSManagedObject subclass" from within my model, and so it automatically creates the classes for my entity.</p>
  
  <p>However, on the declaration of the class, I get this error:</p>
  
  <blockquote>
    <p>Invalid redeclaration of "RoleName"</p>
  </blockquote>
  
  <p>even though I don't have any other class with the same name.</p>
