title: swift - change color of top UIToolbar border
body: <p>I'm trying to change the color of the top border on a UIToolbar.</p>
  
  <p>I tried:</p>
  
  <pre><code>layer.borderWidth = 1
  layer.borderColor = UIColor(r: 250, g: 250, b: 250).CGColor
  </code></pre>
  
  <p>That didn't work. </p>
  
  <p>Suggestions? Thank you</p>
