911 PointsUnresolved '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?

13,515 PointsIt 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()
