title: SwiftyJSON object back to string
body: <p>I'm using the SwiftyJSON library to parse JSON into swift objects. I can create the JSON object and read and write to it</p>
  
  <pre><code>// Create json object to represent library
  var libraryObject = JSON(["name":"mylibrary","tasks":["Task1","Task2","Task3"]])
  
  
      // Get
      println(libraryObject["name"])
      println(libraryObject["tasks"][0])
  
      // Set
      println("Setting first task to 'New Task'")
      libraryObject["tasks"][0] = "New Task"
  
      // Get
      println(libraryObject["tasks"][0])
  
      // Convert object to JSON and print
      println(libraryObject)
  </code></pre>
  
  <p>All of this works as expected. I just want to convert the libraryObject back to a string in JSON format!</p>
  
  <p>The println(libraryObject) command outputs what I want to the console but I can't find a way to get it as a string. </p>
  
  <p>libraryObject.Stringvalue and libraryObject.String both return empty values but when I try eg println("content: "+libraryObject) I get an error trying to append a String to a JSON </p>
