MVVM CoreData FetchedReusltsController
<p>I am trying to start using <code>MVVM</code> with <code>Objective-c</code> but I get some problems with <code>CoreData</code>. I don't know who should handle the <code>fetchedResultsControllerDelegate</code> methods. The <code>viewModel</code> or the <code>viewController</code>?</p>

<p>I think that the viewModel should handle it, but I see too much code to do the same. </p>
