I'm just lost on what to do here.
So the first part of the problem was easy and the second task looked simple too. But I've tried a few different things to solve it and I can't get it. I left my code on the first step because I tried a few different wrong solutions and just don't even know which one of those to post. :P Maybe I'm not getting the question, not sure. I'm just lost here. So any help would be awesome. :)
Here's the task
To access information about a course we can use a URL like: https://api.teamtreehouse.com/course/COURSE_ID. Given the variable courseID, create an absolute URL, named courseURL, to retrieve information about a user's progress on a certain course. It should have a path that's relative to the treehouseBaseURL.
import Foundation let courseID = 25 let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/")

- Since courseURL is absolute, we're going to make it a constant (using 'let', like you used with task 1.)
- We need to use interpolation to include the courseID in our courseURL, and to avoid hardcoding the ID. Essentially, we need to make sure that whatever the value of courseID is appears in the courseURL, without us literally typing in 25. To use interpolation, a backslash and parentheses are used, with the constant typed inside the parentheses.
- We need the courseURL to be relative to the treehouseBaseURL: the 'relativeToURL' identifier is what we should use to specify that as our path.
Example code if you're still stuck:
import Foundation let courseID = 25 let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/") let courseURL = NSURL(string: "course/\(courseID)", relativeToURL: treehouseBaseURL)
