title: editActionsForRowAtIndexPath not executing on iOS 8 with Xcode 7
body: <p>I am testing my application on 3 devices. 2 devices on iOS 9, and one device on iOS 8. On iOS 9 the function <code>editActionsForRowAtIndexPath</code> is working and action is show when I swipe one cell. But on iOS 8, I can't swipe cells.</p>
  
  <p>Here is my code :</p>
  
  <pre><code>func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -&gt; [UITableViewRowAction]? {
      let ShareAction = UITableViewRowAction(style: .Normal, title: "Partager", handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) -&gt; Void in
          if AllArticle[indexPath.row].Title != nil &amp;&amp; AllArticle[indexPath.row].Link != nil {
              var ToShare = []
              if self.search {
                  ToShare = [ArticleFiltered[indexPath.row].Link!]
              } else {
                  ToShare = [AllArticle[indexPath.row].Link!]
              }
              let ActivityViewController = UIActivityViewController(activityItems: ToShare as [AnyObject], applicationActivities: nil)
              self.presentViewController(ActivityViewController, animated: true, completion: {
                  self.TableView.setEditing(false, animated: true)
              })
          }
      })
  
      let FavoriteAction = UITableViewRowAction(style: .Normal, title: "Ajouté aux favoris", handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) -&gt; Void in
  
          if AllArticle[indexPath.row].Favoris {
              let alreadyInView = UIAlertController(title: "Favori déjà ajouté", message: "Cet article fait déjà parti de vos favoris", preferredStyle: .Alert)
              let ActionAlert = UIAlertAction(title: "Ok", style: .Default) { (action) in }
              alreadyInView.addAction(ActionAlert)
              self.presentViewController(alreadyInView, animated: true, completion: nil)
          } else {
              AllArticle[indexPath.row].Favoris = true
              let alreadyInView = UIAlertController(title: "Favori ajouté", message: "Cet article fait maintenant parti de vos favoris", preferredStyle: .Alert)
              let ActionAlert = UIAlertAction(title: "Ok", style: .Default) { (action) in }
              alreadyInView.addAction(ActionAlert)
              self.presentViewController(alreadyInView, animated: true, completion: nil)
              Favorite.append(indexPath.row)
              saveFavoris()
          }
          self.TableView.setEditing(false, animated: true)
      })
  
      FavoriteAction.backgroundColor = UIColor.redColor()
  
      return [ShareAction, FavoriteAction]
  }
  </code></pre>
  
  <p>And of course I added in </p>
  
  <p><strong>ViewDidLoad()</strong></p>
  
  <pre><code>if TableView != nil {
          TableView.delegate = self
          TableView.dataSource = self
          TableView.tableFooterView = UIView(frame: CGRectZero)
          TableView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "tapTableView"))
          TableView.gestureRecognizers?.last?.delegate = self
      }
  </code></pre>
  
  <p>May its Xcode bug ?
  Any ideas ?</p>
  
  <p>Thanks !</p>
