Help with challenge

Can someone please explain how this challenge is done.

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 courseURL = NSURL(string: "/course/\(courseID)", relativeToURL: treehouseBaseURL)
let courseData = NSData(contentsOfURL: courseURL, options: nil, error: nil)

let courseData: NSData = courseURL
