title: UICollectionView inside UITableView
body: <p>So I'm trying to create a collection view inside a tableview following this:

  <p>All is going well until a problem occurs here.</p>
  
  <pre><code>override func tableView(tableView: UITableView, 
  willDisplayCell cell: UITableViewCell, 
  forRowAtIndexPath indexPath: NSIndexPath) {
  
  guard let tableViewCell = cell as? TableViewCell else { return }
  
  tableViewCell.setCollectionViewDataSourceDelegate(self, forRow: indexPath.row)
  }
  </code></pre>
  
  <p>I receive the error 'Cannot invoke 'setCollectionViewDataSourceDelegate' with and argument of list type '(ViewController, forRow: Int)''</p>
  
  <p>What's the problem here?</p>
