iOS Build a Weather App with Swift (Retired) Pulling Data From the Web Creating a URL

NSURL

Hi everyone, i am stuck on this exercise.

This is what i have to do: 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.

I hope you guys can help me with my problem. Greetings Mathis

urls.swift
import Foundation

let courseID = 25
var treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/")
var courseURL = NSURL(courseID, relativeToURL: treehouseBaseURL)

For some reason the backward slash won't appear when I post, but there should be a backward slash before (courseID)

I did what you said but i still have an error: You need to convert the courseID variable to a string and use it when creating courseURL.

you need a backward slash \ before the (courseID)

I know, it stil sais the same : You need to convert the courseID variable to a string and use it when creating courseURL.

I got that error too when I was first trying to solve it. If you use the same code you had before and just make the change I suggested it should work. \ (courseID) should be all you need to convert it to a string. Do you have both the / and a \
