CLLocation Manager in Swift to get Location of User

Question

I am trying to convert an old app in ObjC to Swift as a practice exercise and have ran in to some issues. The way I had it in the old app, it was establishing the CLLocatio

Answer 1

I hope there are two ways.

var locationManager: CLLocationManager = CLLocationManager()
var initialLocation :CLLocation?
var updatedUserLocation :CLLocation?

override func viewDidLoad() {
    super.viewDidLoad() {

    //MapView Location
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
    locationManager.requestWhenInUseAuthorization()
    locationManager.startUpdatingLocation()
    locationManager.startUpdatingHeading()
}

Implementing CLLocationManagerDelegate :

//CLLocationManager Delegate
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    // This only works when user location is updated.
    gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)

}

func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {

    //Error indicates GPS permission restricted

    gpsProviderStatusLabel.changeStatusToOff(gpsProviderStatusLabel)

    //Initial Location
    initialLocation = locations.first

    //Getting Updated Location
    updatedUserLocation = locations.last
}

Checking CLLocationDelegate Authorization:

func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {

    //This method does real time status monitoring.

        switch status {
        case .NotDetermined:
          print(".NotDetermined")
          break

        case .AuthorizedAlways:
          print(".AuthorizedAlways")
          gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
          break


        case .Denied:
          print(".Denied")
          gpsProviderStatusLabel.changeStatusToOff(gpsProviderStatusLabel)
          break

        case .AuthorizedWhenInUse:
          print(".AuthorizedWhenInUse")
          gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
          break

        case .Restricted:
          print(".Restricted")
          break

        default:
          print("Unhandled authorization status")
          break

        }
      }

Note: changeStatusToOn or changeStatusToOff is a UILabel Extenion method which makes the Label text On/Off with Green/Red Colors.
