title: For UITableView do I need to implement trailingSwipeActionsConfigurationForRowAt and/or editActionsForRowAt?
body: <p>iOS11 introduced <code>trailingSwipeActionsConfigurationForRowAt</code> (and leading...). Does that mean I now have to implement </p>
  
  <ol>
  <li>the trailing/leading methods to control swiping for iOS11 <strong>AND</strong></li>
  <li><code>editActionsForRowAt</code> for iOS10? </li>
  </ol>
  
  <p>How to get the simulator to run iOS10 simulations to see how my app behaves in the back level OS? Since everything is now iOS11, I'm not sure how my app will be in that version? </p>
  
  <p>To clarify: I want actions for rows, but I don't want the default behaviour in iOS11 of <code>performsFirstActionWithFullSwipe</code>. If I just implement <code>editActionsForRowAt</code> then iOS11 does the full swipe.</p>
