NSJSONSerialization Swift challenge is based on the outdated version of the class

Seemingly another short-term causality of the updates to XCode and Swift since the course originally began, the challenge expects students to try and solve the challenge with the deprecated use of the dataUsingEncoding class method of NSJSONSerialization despite the course noting for students to adhere to the updated changes.

The updated method requires unwrapping when it previously didn't; this is consistent with the importance of the type safety with Swift that they recognized not being adhered to with the original implementation.

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