title: What is the most succinct way to remove the first character from a string in Swift?
body: <p>I want to delete the first character from a string. So far, the most succinct thing I've come up with is:</p>
  
  <pre><code>display.text = display.text!.substringFromIndex(advance(display.text!.startIndex, 1))
  </code></pre>
  
  <p>I know we can't index into a string with an <code>Int</code> because of Unicode, but this solution seems awfully verbose. Is there another way that I'm overlooking?</p>
