you are on the right track. However your base URL is incorrect. the base URL is https://api.teamtreehouse.com/ not https://api.teamtreehouse.com/\(courseID)/

so for task 1 you need to create the base URL constant using https://api.teamtreehouse.com/ as the url:

import Foundation

let courseID = 25
let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/")

in task 2 we need to create an absolute URL, named courseURL, to retrieve information about a user's progress on a certain course

to obtain info on a course, you use a URL that looks like this: https://api.teamtreehouse.com/course/someCourseID where some courseID is an actual courseID

so the base URL is https://api.teamtreehouse.com/ and the full URL needs to look like https://api.teamtreehouse.com/course/someCourseID. we can construct the full course URL using the NSURL(string: relativeToURL:)method.

we have a course ID variable with a value of 25. we can interpolate that onto the end of the string "course/" to make the second half of the url. we can pass the baseURL in as the relativeToURL argument to build the complete URL that looks like https://api.teamtreehouse.com/course/25 

import Foundation

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

for more information on NSURL and its initalizers, see the NSURL class reference

to learn more about using interpolation in Swift, see the Swift eBook
