How to get accurate user coordinates and stop location manager

Question

I want to get current device location and zoom map to that coordinates.
I also wan't to stop location manager after zoom to user location to prevent changing map visible area if user move.

...viewDidLoad...{
self.locationManager = CLLocationManager();
        self.locationManager.delegate = self;
        self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
        self.mapView.showsUserLocation = true;
        self.locationManager.startUpdatingLocation();
}

func locationManager(manager:CLLocationManager, didUpdateLocations locations:[AnyObject]){
var newRegion = MKCoordinateRegion(center: self.mapView.userLocation.coordinate, span: MKCoordinateSpanMake(0.014, 0.014));
            self.mapView.setRegion(newRegion, animated: true);
            self.locationManager.stopUpdatingLocation();
}

Problem with this code is that this code move map view to ocean and coordinates are sometimes invalid (another continent).
And as I stopped location manager map view stays in the ocean :-/
What is the proper way to make what I want?

You should always omit self. if needed Xcode will ask you to add it. — Leo Dabus, Mar 18 '15 at 23:07

CLLocationManager doesn't always guarantee the accurate coordinates for single delegate invoke(such as when the first delegation invoke). The newRegion may only give you the cached location.
