/**
* @fileoverview
* Registers a language handler for Swift
*
*
* To use, include prettify.js and this file in your HTML page.
* Then put your code in an HTML tag like
* <pre class="prettyprint lang-swift">(my swift code)</pre>
* This file supports the following language extensions:
* lang-swift - Swift
*
* I used https://developer.apple.com/library/ios/documentation/Swift/Conceptual/Swift_Programming_Language/AboutTheLanguageReference.html
* as the source of truth for this. The revision from 2015-10-21 (Swift 2.1) was used in most recent update.
