title: Case insensitive Dictionary in Swift
body: <p>Given a <code>Dictionary</code> whose <code>Key</code> is of type <code>String</code>, is there a way to access the value in a case-insensitive manner? For example:</p>
  
  <pre><code>let dict = [
      "name": "John",
      "location": "Chicago"
  ]
  </code></pre>
  
  <p>Is there a way to call <code>dict["NAME"], dict["nAmE"]</code>, etc. and stil get <code>"John"</code>?</p>
