title: Swift - Editor placeholder in source file
body: <p>I am new to swift and I was following an open source tutorial to learn Swift, however one error keeps cropping up - "Editor placeholder in source code" This is the code:</p>
  
  <pre><code>func setupGameLogic (){
      for index in 0 ... fields.count - 1{
          let gestureRecogniser = UITapGestureRecognizer(target: self, action: Selector("fieldTapped:"))
          gestureRecogniser.numberOfTapsRequired = 1
  
          fields[index].addGestureRecognizer(gestureRecognizer:  UIGestureRecognizer) //Editor placeholder in source file
      }
  }
  </code></pre>
