title: How do I draw a circle in iOS Swift?
body: <pre><code>let block = UIView(frame: CGRectMake(cellWidth-25, cellHeight/2-8, 16, 16))
  block.backgroundColor = UIColor(netHex: 0xff3b30)
  block.layer.cornerRadius = 9
  block.clipsToBounds = true
  </code></pre>
  
  <p>This is what I have right now, but it's obviously not the right way to do it.</p>
  
  <p>What's the simplest way to do it?</p>
