Courses Plus Student 4,431 PointsdownloadTaskWithURL gives compiler error!
downloadTask in the Weather app gives me compiler error and I don't get what I've done wrong. I have typed in the code exactly like the video.
'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: "59.307469,18.075581", relativeToURL: baseURL)
let sharedSession = NSURLSession.sharedSession()
let downloadTask: NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(forecastURL, completionHandler: { (location: <#NSURL!#>, response: <#NSURLResponse!#>, error: <#NSError!#>) -> Void in
println(response, error)
})
downloadTask.resume()
}'
When I try to run this code it gives me the compiler error "Expected an identifier to name generic parameter" and "Expected parameter type following :" and points at the downloadTask-section. What have I done wrong?

In my case, I was getting the error and NSURL!, NSURLResponse!,and NSError! were highlighted in dark blue. I was able to double-click each of the and XCode was satisfied. I am thinking it has something to do with highlighting the entire completionHandler singleton and hitting ENTER to let XCode fill it out.
Running XCode 6.1.1
