I am trying to retrieve data from the treehouse API and store it on courseData on one of the challenges but I must be missing something because is not working
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)

42,016 Pointsthe teachers notes of this video state:
This course uses Xcode 6.0.1 and since its release, Xcode has been updated to 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)
Since the challenge has been updated to use the new way of doing it, you just need to change your code to use the NSData initializer:
import Foundation
let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/")
let courseURL = NSURL(string: "/course/\(courseID)", relativeToURL: treehouseBaseURL)
let courseData = NSData(contentsOfURL: courseURL, options: nil, error: nil)
