Need help with working with JSON code challenge

When I submit my code I get an unresolved variable even though it says “The code you write in each task should be added to the code written in the previous task.”

import Foundation

let jsonString : NSString = "{\"results\": \"success\"}"
let userCourseData : NSData = (contentsOfURL: courseURL)

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

you may need something like this:

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

at the end of your code you have two spaces just before as Dictionary

No that didn't work. I still get the unresolved identifier.

it looks like the code challenges may not be working right now. looking at your code it seems correct, however when I submit it I get a communication error.
