title: Core Data error - Swift
body: <p>I'd like to use this line of code, but xcode says: <code>Type 'ViewController' does not conform protocol 'NSFetchedResultsControllerDelegate'</code></p>
  
  <p>Code:</p>
  
  <pre><code>fetchedResultController.delegate = self
  </code></pre>
  
  <p>Does someone have a solution for this?</p>
