Getting nil response

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

    let forecastURL = NSURL(string: "36.494081,-80.603625", 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'm still getting an nil response and my coordinates don't have a space.

Any idea's

Try unwrapping baseURL like this: 

let forecastURL = NSURL(string: "36.494081,-80.603625", relativeToURL: baseURL!)

Legend thanks Enara, worked perfectly!

I've got to get my head around unwrapping, still a little confused by it!
