Convert the JSON data to an NSDictionary and store it in a constant named userCourseDictionary

need some help

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
let userCourseDictionary: NSDictionary = NSJSONDictionary.NSData(contentsOfURL: courseURL) as NSDictionary

Hey, I went to the video your question referenced. The code needed to solve the challenge is discussed around 3:20. It looks like you have the variable type and downcasting set up, but in this case there's no need to reference a url since they already stored the json string as a constant, "jsonString". Basically, on the last line after the = sign, you just need to call the NSJSONSerialization.JSONObjectWithData() method on the json object like this:

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

Let me know if that works for you!
