Show Current Location and Update Location in MKMapView in Swift

You have to override CLLocationManager.didUpdateLocations (part of CLLocationManagerDelegate) to get notified when the location manager retrieves the current location:

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {    if let location = locations.last{        let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)        let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01)), animated: true)    }}

NOTE: If your target is iOS 8 or above, you must include the NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key in your Info.plist to get the location services to work.

100% working, easy steps and tested

Import libraries:

import MapKitimport CoreLocation

set delegates:


Take variable:

let locationManager = CLLocationManager()

write this code on viewDidLoad():

self.locationManager.requestAlwaysAuthorization()    // For use in foreground    self.locationManager.requestWhenInUseAuthorization()    if CLLocationManager.locationServicesEnabled() {        locationManager.delegate = self        locationManager.desiredAccuracy = kCLLocationAccuracyBest        locationManager.startUpdatingLocation()    }    mapView.delegate = self    mapView.mapType = .standard    mapView.isZoomEnabled = true    mapView.isScrollEnabled = true    if let coor = mapView.userLocation.location?.coordinate{        mapView.setCenter(coor, animated: true)    }

Write delegate method for location:

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {    let locValue:CLLocationCoordinate2D = manager.location!.coordinate    mapView.mapType = MKMapType.standard    let span = MKCoordinateSpanMake(0.05, 0.05)    let region = MKCoordinateRegion(center: locValue, span: span)    mapView.setRegion(region, animated: true)    let annotation = MKPointAnnotation()    annotation.coordinate = locValue    annotation.title = "Javed Multani"    annotation.subtitle = "current location"    mapView.addAnnotation(annotation)    //centerMap(locValue)}

Do not forgot to set permission in info.plist

<key>NSLocationWhenInUseUsageDescription</key><string>This application requires location services to work</string><key>NSLocationAlwaysUsageDescription</key><string>This application requires location services to work</string>

It's look like:

For swift 3 and XCode 8 I find this answer:

  • First, you need set privacy into info.plist. Insert string NSLocationWhenInUseUsageDescription with your description why you want get user location. For example, set string "For map in application".

  • Second, use this code example

    @IBOutlet weak var mapView: MKMapView!private var locationManager: CLLocationManager!private var currentLocation: CLLocation?override func viewDidLoad() {    super.viewDidLoad()    mapView.delegate = self    locationManager = CLLocationManager()    locationManager.delegate = self    locationManager.desiredAccuracy = kCLLocationAccuracyBest    // Check for Location Services    if CLLocationManager.locationServicesEnabled() {        locationManager.requestWhenInUseAuthorization()        locationManager.startUpdatingLocation()    }}// MARK - CLLocationManagerDelegatefunc locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {    defer { currentLocation = locations.last }    if currentLocation == nil {        // Zoom to user location        if let userLocation = locations.last {            let viewRegion = MKCoordinateRegionMakeWithDistance(userLocation.coordinate, 2000, 2000)            mapView.setRegion(viewRegion, animated: false)        }    }}
  • Third, set User Location flag in storyboard for mapView.
