title: Increase touch target size of UISlider with Swift
body: <p>I managed to increase the thumb size of my <code>UISlider</code> with <code>Swift</code> but the touch zone is still too small for my application.</p>
  
  <p>How to programmatically increase the size of the touch zone for a <code>UISlider</code>?</p>
  
  <p>Should I re-implement a custom slider by myself?</p>
  
  <p>Thank you!</p>
