Hi Allan,

Your method call is not quite right. Here's the correct syntax:

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)

Note: I haven't seen the video recently, but Swift is a young, changing language, and it's entirely possible the video shows a different way to call this method which has since been changed. When in doubt, check Apple's documentation! Being able to find and understand the entry in the docs you need is a great skill to master.

Thanks, yes I am quiet sure it is changing, but I thought that the answer was based on the video content. I appreciate your help!
