title: Multiple lined UIAlertController message
body: <p>Is there a way to format the message (not the title) string of a UIAlertController to show multiple lines? I've tried the "/n" character and that doesn't work. I also can't use NSString and formatting it. </p>
  
  <p>Thanks!</p>
  
  <p>Edit: d'oh it should have been \n not /n. Here's the correct code</p>
  
  <pre><code>let alertController = UIAlertController(title: "blah", message: "1. blah \n2. blah \n3. blah", preferredStyle: .actionSheet)
  </code></pre>
