CLLocationManager is slow getting location, Swift

Question

Im creating this app, and it needs to get the users location - its all working properly, the thing is, that the time from accepting the use of location services, to getting the actual location takes like 5 seconds - is this normal? I've used other apps, where it goes much faster..

Here's what my code looks like:

override func viewDidLoad() {
    super.viewDidLoad()

    // Ask for Location-Authorisation from the User.
    self.locationManager.requestWhenInUseAuthorization()

    if CLLocationManager.locationServicesEnabled() {
        locationManager.delegate = self
        locationManager.requestLocation()
    }

    mapView.delegate = self

}



func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let locValue: CLLocationCoordinate2D = manager.location!.coordinate

    let initialLocation = CLLocation(latitude: locValue.latitude, longitude: locValue.longitude)

    self.centerMapOnLocation(initialLocation)
}

func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
    print("could not get location")
}

But the time from the application gets the location to put into the centerMapOnLocation-function, seems just to be quite long. What is to be expected, when getting a users location? I'm testing on a wifi connection, so I know its not because the internet is slow, or its a bad connection...

Anyone have an idea? :)

Best regards!

When initializing your location manager, add startUpdatingLocation():

let manager = CLLocationManager()
 manager.delegate = self
 manager.requestWhenInUseAuthorization()
 manager.requestLocation()
 manager.startUpdatingLocation()

Without startUpdatingLocation() geo-location takes about 5 seconds, with it, the request executes nearly immediately.
