Build a Weather App in Swift Concurrent Code

I am getting a red "stop sign" that says when I click on it that items in series must be separated by a "," but everything is. The error is on the "let downloadTask" line.

Can anyone please help to give me a clue on how to solve this?

Here is the code:

let downloadTask: NSURLSessionDownloadTaskWithURL(forecastURL, completionHandler: {(location:NSURL!,response:NSURLResopnse!, error: NSError!) -> Void in code
            println(response)

It looks like one of the auto complete snippets didn't expand. It should look something like this,

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

Everything was correct but for the "!" after the forecastURL. Thank you Daniel!

It is pretty though to answer as I do not know at what point you are in the making of the app.

But I think this misses the actual calling of the concurrent task..

Something like " = sharedSession.downloadTaskWithURL" right after NSURLSessionDownloadTaskWithURL, but I am not 100% sure
