title: Pan gesture in UITableViewCell that can move image view all over tableview without going beneath the cell
body: <p>I am trying to create a tinder like swipe left and right in UITableView cell. Here, the tableview cell contains an image view which I can move around with pan gesture. When I initiate the gesture on the image view, I want to move it freely over my device screen.</p>
  
  <p>I am facing the problem that when I move the image view around it goes below the current cell. How can I bring the image view over all others so it doesn't go below the cell frame?</p>
  
  <p>I tried using <code>view.bringSubviewToFront</code> but it doesn't work.</p>
  
  <p>Please suggest a way I can achieve this.</p>
