Courses Plus Student 2,801 PointsI'm stuck on this challenge!
The challenge is: 'To access information about a course we can use a URL like: https://api.teamtreehouse.com/course/COURSE_ID. Given the variable treehouseCourseID, create an absolute URL, named courseURL, to retrieve information about a user's progress on a certain course. It should have a path that's relative to the treehouseBaseURL.'
I have attached my code below. What's wrong?
Please HELP ASAP!
Thanks.
import Foundation
let treehouseCourseID = 25
// Add your code below
let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/")
let courseURL = NSURL(string: "https://api.teamtreehouse.com/course/\(treehouseCourseID)", relativeToURL: treehouseBaseURL)

import Foundation
let treehouseCourseID = 25
// Add your code below
let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/“)
// Since the base URL already holds most of the link that does not change,
// you don’t have to add the whole link, you only add the second part.
let courseURL = NSURL(string: "course/\(treehouseCourseID)", relativeToURL: treehouseBaseURL)
Hope it helps
