Une très simple Swift CoreLocation exemple de travail

J'ai essayé de suivre simple CoreLocation des exemples d'utilisation de Swift, mais je ne suis pas en mesure d'obtenir les choses de travail. J'ai extrait la plupart du code, donc c'est juste barebones afin de concentrer la question, et j'espère que la réponse saute rapidement à quelqu'un.

import UIKit

import CoreLocation


class ViewController: UIViewController,CLLocationManagerDelegate {
@IBOutlet weak var txtLatitude: UITextField!
@IBOutlet weak var txtLongitude: UITextField!

@IBOutlet weak var cmdLocateMe: UIButton!
@IBOutlet weak var slider: UISlider!
@IBOutlet weak var txtSlider: UITextField!
@IBOutlet weak var power: UISwitch!
var locationManager: CLLocationManager!


override func viewDidLoad() {
    locationManager = CLLocationManager();
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.startUpdatingLocation();
    super.viewDidLoad()


    //Do any additional setup after loading the view, typically from a nib.
}

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


@IBAction func valueChanged(sender: UISlider) {
    if power.on{
    var val = "\(slider.value)";
    txtSlider.text = val;
    }
}


@IBAction func cmdLocateMeClicked(sender: UIButton) {


}

//Deprecated
@IBAction func cmdLocateMePressed(sender: AnyObject) {
}

//CLLocationManagerDelegate
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    var location:CLLocation = locations[locations.count-1] as CLLocation

    println("locations = \(locations)")
    txtLatitude.text = "\(location.coordinate.latitude)";
    txtLongitude.text = "\(location.coordinate.longitude)";
}

func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
    println(error)
    txtLatitude.text = "Can't get your location!"
}

}
