Open Radar

 
Summary:
Calling [NSManagedObjectModel initWithContentsOfURL:] opens Core Data model (.mom) files in read-write mode.

I believe that this does not cause the app to write to the model file. That may make the issue seem insignificant, but it was a big deal for me. It caused the App Review team to reject my app on the grounds that it tries to write to that file, even though it does not.  It took 8 days and a technical support incident to learn why the App Review team believed that the app was trying to write to the Core Data model file.
