you need to use string interpolation to interpolate the course ID onto the end of the string.

since the full url used to access a course looks something like "https://api.teamtreehouse.com/course/COURSE_ID", you can see that /course/COURSE_ID is the part of the url thats going to be relative to the base URL, which is "https://api.teamtreehouse.com/".

so interpolate the value of courseID onto the end of the string "course/" and use that as the string parameter.

import Foundation

let courseID = 25
let treehouseBaseURL = NSURL(string:"https://api.teamtreehouse.com/");
let courseURL = NSURL(string: "course/\(courseID)", relativeToURL: treehouseBaseURL);
