title: Fatal Exception: NSInternalInconsistencyException - Xcode
body: <p>for a Customer I should fix two crashes with CoreData.</p>
  <ul>
  <li><p>This NSPersistentStoreCoordinator has no persistent stores (schema mismatch or migration failure). It cannot perform a save operation.</p>
  </li>
  <li><p>This NSPersistentStoreCoordinator has no persistent stores (disk full). It cannot perform a save operation.</p>
  </li>
  </ul>
  <p>There are no differences in the entities, the model is the same: I cannot reproduce the crash that I look on Firebase.</p>
  <p>Everything seems correct: I have experience with coredata and have checked every possible problem of Migration, etc.</p>
  <p>Any suggestion?</p>
