I'm currently working on a UITableViewController demo which works just the way I wanted it to work.

The only thing I don't get is the missing delete button, when swiping to the left on a row.

The "space" of the button and also the delete functionality are there, but neither the red rectangle button nor the text "delete" shows up.

This happens in the simulator and also on the device.

Of course, I have implemented "edititingStyleForRowAtIndexPath'

```
override func tableView(tableView: UITableView, editingStyleForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCellEditingStyle {
    switch indexPath.section{
    case SectionConstants.MODEL_DATA_SECTION: return UITableViewCellEditingStyle.Delete
    case SectionConstants.NEW_DATA_SECTION: return UITableViewCellEditingStyle.Insert
    default: return UITableViewCellEditingStyle.None
    }
}

```

and 'commitEditingStyle' which is irrelevant for this, as it is triggered after the delete button has been touched.

Does anyone have any idea what could cause this behavior or faced a similar issue?

Best regards,
Steffen
