  <a href="https://i.stack.imgur.com/TdGom.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TdGom.png" alt="Cancel Button"></a></p>
  
  <p>I want to swipe their places During run time.</p>
  
  <p>I've tried the <code>translatesAutoresizingMaskIntoConstraints</code> option but it's misbehave in many scenarios.
  also I can't just outlet some constrains and change their constants during run time because the two buttons are related to each other </p>
  
  <p>What to do ? </p>
