title: Swift change cgpoint .center value
body: <p>I am using a CGPoint value to set where a animation starts.</p>
  
  <pre><code>transition.startingPoint = startButton.center
  </code></pre>
  
  <p>If I do <code>print(startButton.center)</code> the output will be: <code>(292.0, 22.0)</code></p>
  
  <p>What I now want to do is to edit that values Y position so the animation starts a bit lower on the screen and I can pass the new value to the <code>transition.startingPoint = newVal</code></p>
