title: Add swipe gesture recogniser to uilabel (swift)
body: <pre><code>        let urgencyLabel = UILabel(frame:CGRectMake(renderWidth,0,80,60))
          urgencyLabel.text = "Urgency"
          view.addSubview(urgencyLabel)
  </code></pre>
  
  <p>How can i add a swipe left gesture recogniser to uilabel instead of whole view controller?</p>
