How do I create a base URL using the NSURL class?
I've tried this challenge for like 30 minutes :0 I hope its not an embarrassing mistake.
import Foundation let courseID = 25 let treehouseBaseURL = NSURL (String: "https://api.teamtreehouse.com/\(courseID)")

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!
I'm Having the same problem.... Any idea where I'm going wrong, code is identical o answer above: 'import Foundation
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!
The 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.
