Instance of NSURL

import Foundation

let treehouseCourseID = 25

let baseURL = NSURL(string: "https://api.teamtreehouse.com/")

let treehouseBaseURL = NSURL(string: "" , relativeToURL: baseURL)

let courseURL = NSURL(string: "(treehouseBaseURL)course/(treehouseCourseID)")

"Bummer! Make sure you're assigning an instance of NSURL to courseURL"

I can't seem to find the problem?

urls.swift 
import Foundation

let treehouseCourseID = 25

let baseURL = NSURL(string: "https://api.teamtreehouse.com/")

let treehouseBaseURL = NSURL(string: "" , relativeToURL: baseURL)

let courseURL = NSURL(string: "\(treehouseBaseURL)course/\(treehouseCourseID)")

Here's how this should look: 

import Foundation
let treehouseCourseID = 25

// Setting up Base URL
let treehousebaseURL = NSURL (string: "https://api.teamtreehouse.com/") 
// courseURL consists of "/course/25" with treehouseBaseURL infront.
let courseURL = NSURL (string: "course/\(treehouseCourseID)", relativeToURL: treehouseBaseURL)

Hope this helps!
