title: UITableView "bulk select" not showing selected checkmarks in the selection circles, showing right side checkmark not left side
body: <p>I am attempting to reproduce this behavior (see screenshot below, the "mail multiple select to delete" behavior) on an iOS8 Swift application. <strong>When set to "edit" the left selection circles are presented, but upon selection they do not change to a blue checkmark.</strong> (Nothing visible happens, or it happens off to the right ... off screen.)</p>
  
  <p>From various Google searches I've tried setting the accessoryType to be checkbox, but that appears on the right (not the left.) [Is that old advice, is adding a checkmark still the approach to take?]</p>
  
  <p>I've scoured this sample (even downloading it and running it and tweaking it closer to my code, and it works) but I cannot see the delta between it and my application.</p>
  
  <p>Some data points:</p>
  
  <ul>
  <li>Xcode 7</li>
  <li>iOS8 + (testing on 8 and 9)</li>
  <li>Swift 2.0</li>
  <li>Storyboard configuration of the tableview, etc.</li>
  <li>Custom layout cells. They use the content view for some text, nothing outside. Autolayout.</li>
  <li>Single selection when NOT editing (or so I believe)</li>
  <li>Multiple selection when editing (to get this effect.)</li>
  <li>DataSource returns canEdit "true" for most (not all) cells. Circles only show next to those editable, matching expectations.</li>
  <li>Delegate is not returning any "editing style" value. (Tried w/ &amp; w/o.)</li>
  <li>Delegate does NOT deselect in "didSelect" handler.</li>
  <li>When I try setting accesoryType to Checkmark in didSelect (which many posting suggest, but I don't see it in the sample) it comes on the right not left. </li>
  </ul>
  
  <p>Other StackOverflow questions / answers imply something is causing UITableView to fail to know to put the checkmark on the left not the right. I can believe that, but I cannot find it. Any help appreciated.</p>
  
  <p><strong>The desired effect (from sample screenshot):</strong> </p>
