It looks like that you have typed string with capital s on the line you declare the treehouseBaseURL variable. It should be lowercase so try this:
let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/\(courseID)")
Hope this helps!

let courseID = 25 let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/\(courseID)")
Error is: Bummer! The URL string assigned to the NSURL isn't correct - please double-check it!

Damion Marshall
iOS Development Techdegree Student 5,594 PointsThe problem is your courseID is an Int must use the String(treehouseCourseID) to type cast. Also the entire url should read.
let courseURL = NSURL (string: "https://api.teamtreehouse.com/course/25")
Don't forget to add the "/course" before the course_id.
