Can anyone explain why this code does not work?

I think I have successfully assigned the value from the NSData class method to the courseData constant, but I keep getting an error on the code challenge. Can anyone help?

students_code.swift 
import Foundation
let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/")
let courseURL = NSURL(string: "/course/\(courseID)", relativeToURL: treehouseBaseURL)
let courseData = NSData.dataWithContentsOfURL(courseURL, options: nil error: nil)

In the Teacher's notes Pasan wrote that there are some changes in Xcode 6.1:

"[....] In the process some changes have been made to the APIs we work with in this course and in this particular video, the use of the NSData class initializer has been modified from

NSData.dataWithContentsOfURL(url: NSURL, options: NSDataReadingOptions, error: NSErrorPointer)

to

NSData(contentsOfURL: NSURL, options: NSDataReadingOptions, error: NSErrorPointer)

[...]"

so you must use the second notation to pass the challenge.
