I don't understand why it doesn't work, I checked the video and it is the right code

I get the message: "You need to assign the result of NSData to the constant courseData", which I do!

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)

Hello Florent,

Try this.

 courseData = NSData(contentsOfURL: coureseURL!)

Sorry, if this is such a vague question. Why did this work?

I used the same code as Florent and was receiving the same error. The other thing that boggles my mind is that we didn't even declare courseData as a constant, correct? Such as "let CourseData" ... so I'm just curious why this worked and Florent's code didn't. Was there a bug in this challenge?
