Im having problem here

Let's assume that the courseURL we created earlier returns some JSON data from Treehouse API. Create a data object to capture this information, and store it in a constant named courseData. Hint: Use the NSData class. You can set options and error to nil.

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, option: nil, error: nil)

Brighton,

You almost have it. Your missing the contentsOfURL.. see below

:) 

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)
