cant get it working
Here is my Code: import Foundation
let courseID = 25
let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/")
let courseURL = NSURL(string:"courseID", relativeToURL: treehouseBaseURL)
I am aware the in the URL there is the "/course/" missing, but I dont know how to add this, or where. Also I think I need to convert the courseID = 25 into a string and I am not sure if a "25" will do the work.
Any hints? Would be great!

this challenge is pretty tough since it does not really give you much direction.
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);
