title: CGRect.offsetBy Not Working
body: <p>How do I rewrite the code below?</p>
  
  <pre><code>self.view.frame = CGRectOffset(self.view.frame, 0, movement)
  </code></pre>
  
  <blockquote>
    <p>'Offset' has been replaced by 'offsetby'</p>
  </blockquote>
  
  <p>When I replaced it with the so called "solution":</p>
  
  <pre><code>self.view.frame = CGRect.offsetby(self.view.frame, 0, movement)
  </code></pre>
  
  <p>I receive an error:</p>
  
  <blockquote>
    <p>"Instance member 'offsetBy' cannot be used on type 'CGRect'; did you mean to use a value of this type instead?"</p>
  </blockquote>
