title: Trying to use setNeedsDisplay()
body: <p>I'm trying to reload the UIView. Actually I get an error</p>
  
  <blockquote>
    <p>Cannot convert value of type 'HomeViewController' to expected argument type 'UIView'</p>
  </blockquote>
  
  <p>So this is the code:</p>
  
  <pre><code>UIView.setNeedsDisplay(self)
  </code></pre>
  
  <p>Do you have any idea?</p>
