title: how to parse string array with SwiftyJSON?
body: <p>Using <code>SwiftyJSON</code> how would I parse the following JSON array into a <code>Swift [String]</code>?</p>
  
  <pre><code>{
      "array": ["one", "two", "three"]
  }
  </code></pre>
  
  <p>I have tried this code, but it doesn't work for me:</p>
  
  <pre><code>for (index: String, obj: JSON) in json["array"] {
          println(obj.stringValue)
      }
  </code></pre>
  
  <p>What would be the best way to handle this? Thank you.</p>
