title: Fetch only Parent entity's data in Core Data where Parent Child entity has 1 to M relationship

Country to Region has 1 to Many relationship. If I fetch country(by CountryID predicate) it returns specific Country properties with all relative Region.</p>
  
  <p>In my case I don't need Region data(contains huge data). How it possible?</p>
  
  <p>Following thread saying, <strong>includesSubentities</strong> of NSFetchRequest can do that. But its not working for me!</p>
