Json swift challenge . help?

Let's assume we have a data object named userCourseData. We'll mock the data in this challenge, but it could easily have been returned from the Treehouse API with the code: let userCourseData = NSData(contentsOfURL: courseURL). Convert the JSON data to an NSDictionary and store it in a constant named userCourseDictionary. Hint: use the NSJSONSerialization class.

json.swift 
// We've already created a NSData object with some json encoded data for you
import Foundation

let jsonString : NSString = "{\"results\": \"success\"}"
let userCourseData : NSData = jsonString.dataUsingEncoding(NSUTF8StringEncoding)!

// Now you just need to decode it

You need to add this line of code after the creating the userCourseData instance

let userCourseDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(userCourseData, options: nil, error: nil) as NSDictionary
