Swift weather app println function

In the video when he calls the println(currentWeatherDictionary) all of the information is printed out, nothing happens with my code

import UIKit

class ViewController: UIViewController {

//Replace the string below with your API Key.
private let apiKey = "d22b3b492d25282da275e826cc50757b"

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: "43.067827,-77.541085", 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 currentWeatherDictionary: NSDictionary = weatherDictionary["currently"] as NSDictionary

            println(currentWeatherDictionary)

        }

    })

    downloadTask.resume()
}

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

}
