title: Custom UITableViewCell editing mode not working
body: <p>i'm currently working on an app for iOS 7 and iOS 8 with Xcode 6 build 7 coding with Swift. In one of the view controllers I got a tableview with custom cells, the thing is, that when I set the tableview property editing to "true", nothing occurs, I don't see the delete button, but if I use a default cell instead of mine it works.</p>
  
  <p>I've used all the necessary methods </p>
  
  <pre><code>func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -&gt; Bool {
      return true
  }
  
  func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
      if (editingStyle == UITableViewCellEditingStyle.Delete) {
          // handle delete (by removing the data from your array and updating the tableview)
      }
  }
  
  func tableView(tableView: UITableView, editingStyleForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCellEditingStyle {
      return .Delete
  }
  </code></pre>
  
  <p>but nothing happens, anyone has had the same problem?</p>
  
  <p>Thanks!!</p>
