iOS Build a Weather App with Swift (Retired) Pulling Data From the Web Fetching JSON Data

how do i correct my code

lets assume that the courseURL we xcreated earlier returns a JSON data from Treehouse API . Create a data object to capture this information and store it in a constant named courseData. Hint: Use the NSData class. You can set options and error to nil.

import Foundation
let treehouseBaseURL = NSURL(string: "https://api.teamtreehouse.com/")
let courseURL = NSURL(string: "/course/\(courseID)", relativeToURL: treehouseBaseURL)
let courseData = NSData.treehouseBaseURL(courseURL, options:nil , error:nil)

You are calling an instance method that doesn't exist on an uninitialised type. You want to call a class method that creates an NSData object based on the contents of the URL.

I would rewatch the previous video or look in the documentation to solve this rather than someone just giving you and answer.

thanks hey. i still have no solid solution yet
