title: Adding UILongPressGesture to UITableView in iOS13
body: <p>I've been using <code>UILongPressGesture</code> with <code>UITableView</code> for over a year, but I found that this doesn't work in iOS13.</p>
  
  <p>In iOS13, Apple added this gesture to <code>UIScrollView</code> and I'm not sure it is safe to replace it to my own.</p>
  
  <pre><code>&lt;UIScrollViewKnobLongPressGestureRecognizer: 0x7f938c051c00; state = Possible; target= &lt;(action=_handleKnobLongPressGesture:, target= 0x7f938991b000&gt;)&gt;&gt;
  </code></pre>
  
  <p>Anyone knows about this issue? or knows what <code>_handleKnobLongPressGesture</code> action for?</p>
