Unresolved 'location' Swift weather app

Here is the code from my view controller:

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

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

    let forecastURL = NSURL(string: "37.8267,-122.423", relativeToURL: baseURL)

    let weatherData = NSData(contentsOfURL: forecastURL!, options:nil, error:nil)


    let sharedSession = NSURLSession.sharedSession()
    let downloadTask: NSURLSessionDownloadTask =

    sharedSession.downloadTaskWithURL(forecastURL!, completionHandler:
        { (loction: NSURL!, response: NSURLResponse!, error: NSError!) -> Void in

            var urlContents =
                NSString(contentsOfURL: location, encoding: NSUTF8StringEncoding, error: nil)
                println(urlContents)



    })

    downloadTask.resume()

}

Where I declare var urlContents, it tells me: " Use of unresolved identifier 'location' "

Any ideas?

It looks like there may be some things missing... Here is my full ViewController file, see if you can spot any differences.

class ViewController: UIViewController {

    private let apiKey = "dfcab39e1ccac98afcf3944424d70c4e"

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.


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

        let forecastURL = NSURL(string: "37.8267,-122.423", relativeToURL: baseURL)

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

        if (error == nil) {
            let dataObject = NSData(contentsOfURL: location)
            let weatherDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataObject, options: nil, error: nil) as NSDictionary

            let currentWeather = Current(weatherDictionary: weatherDictionary)
            println(currentWeather.currentTime!)






            }

        })
        downloadTask.resume()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}
