iOS Build a Weather App with Swift (Retired) Pulling Data From the Web Creating a URL

I'm stumped

I have been over the lesson a few times now and I just can't see why my code for this challenge is not working.

Can anyone help please?

let courseID = 25

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

The resulting URL should be like this: "https://api.teamtreehouse.com/course/COURSE_ID" The courseURL you are creating is : "https://api.teamtreehouse.com/COURSE_ID" because the string parameter you're passsing is only the courseID.

It should be "course/(courseID)"

import Foundation

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

Thank you :)
