title: CGAffineTransformConCat/ CGAffineTransformMakeScale in Swift 3
body: <p>I'm trying to update a part of a function for swift 3:</p>
  
  <pre><code>  let newLabelOffset = CGFloat(direction.rawValue) * originalFrame.size.height/2
  
      newLabel.transform = CGAffineTransformConCat(
        CGAffineTransformMakeScale(1,0)
        CGAffineTransformMakeTranslation(0,newLabelOffset)
      )
  </code></pre>
  
  <p>I've heard that the new way of using <code>CGAffineTransformConCat</code> is <code>concatenating(_:)</code> but not entirely sure how to set it up based on the 2 above transforms.</p>
