title: Xcode8 'Could not load NIB in bundle'
body: <p>Since I have upgraded my project to xcode8 and swift3 I am having troubles when running my app on ios10 devices and simulators.</p>
  
  <p>I can start the app normally but after a while using it I get the following error:</p>
  
  <pre><code>*** Terminating app due to uncaught exception   
  'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle:
  'NSBundle &lt;/Users/****/Library/Developer/CoreSimulator/Devices/****/data/Containers/Bundle/Application/****/*****.app&gt; (loaded)' 
  with name 'Ncx-Ud-4zl-view-1i6-0r-ivc' and directory 'Main.storyboardc''
  ***
  </code></pre>
  
  <p>The strange thing is that I can navigate through the same menu or view sometimes and after 3 or 4 times it gives me the error.</p>
  
  <p>The app works properly on ios9 devices.</p>
  
  <p>Update:
  I finally solved it updating my CoreDataStackManager class to the Swift3 sintax and also avoiding using caches on my NSFetchedResultsControllers.</p>
