Response nil

I have tried all options from other users who asked questions regarding this video and no matter what Im still getting a nil response.

let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)/")

        let forecastURL = NSURL(string: "39.968612,-82.993032", relativeToURL: baseURL)

        let sharedSession = NSURLSession.sharedSession()

        let downloadTask: NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(forecastURL!, completionHandler: { (location: NSURL!, response: NSURLResponse!, error: NSError!) -> Void in
            println(response)
        })


        downloadTask.resume()

I've copied your code and it seems to be working for me. Is if possible your api key is not correct?

It seems to have worked for me today as well! Thanks for the quick reply. Maybe Xcode just needed reset? who knows.
