title: Error could not dequeue a view of kind UICollectionElementKindCell
body: <p>Taking first plunge with collection views and am running into this error:</p>
  
  <blockquote>
    <p>Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'could not dequeue a view of kind: UICollectionElementKindCell with identifier Cell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'</p>
  </blockquote>
  
  <p>The code is very simple, as shown below. I can't for the life of me figure out what it is that I'm missing. </p>
  
  <pre><code>- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
  {
  UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
  cell.backgroundColor = [UIColor whiteColor]; 
  return cell;
  }
  </code></pre>
  
  <p>The collection view controller was created using a nib and the delegates &amp; datasources are both set to file's owner. </p>
  
  <p>View Controller's header file is also really basic.  </p>
  
  <pre><code>@interface NewMobialViewController_3 : UICollectionViewController &lt;UICollectionViewDataSource, UICollectionViewDelegateFlowLayout&gt;
  @end
  </code></pre>
