Help with challenge

I can't figure out what I am doing wrong with this challenge

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

There are two issues with your code. First, take a look at the color coding in your code (granted this wouldn't have helped you in the code challenge itself because of how code is colored there). You should see immediately where the last line of code doesn't match the prior two. Hint: you have two = symbols on the same line...

Second, you need to pass an actual NSData object to the method JSONObjectWithData(). Instead you're passing it the type NSData. This is where you'll pass in the NSData object the challenge says it's created for you in that first comment.

Here's the solution:

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