Hey Florian Groussin,

You have the set up correct, you're just not creating the proper URL in the end.

Your final URL must follow this format. https://api.teamtreehouse.com/course/COURSE_ID.

import Foundation

let treehouseCourseID = 25

// Add your code below

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

Good Luck

You were doing string interpolation correctly.

/* https://api.teamtreehouse.com/course/\(treehouseCourseID) is the full link we need

You currently have treehouseBaseURL set to this part:
https://api.teamtreehouse.com/

So, your courseURL needs to add this part:
course/\(treehouseCourseID)

Relative to your treehouseBaseURL

This makes the full link
https://api.teamtreehouse.com/course/\(treehouseCourseID)

*/

Viel Glück
