MapKit - Show the current location

Update: April 27, 2017 with Xcode 8.3.2 (Swift 3.1).

1. Add the mapkit in the storyboard and edit the code as below:

import CoreLocation

import MapKit

class ViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate {

@IBOutlet weak var theMap: MKMapView!

2. Edit the info.plist file by adding these two items:

NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription (Update: This is not essential)

3. Edit the code as below:

import UIKit

import CoreLocation

import MapKit

class ViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate {

    @IBOutlet weak var theMap: MKMapView!

    

    //Declare locationManager here to prevent location access message from disappearance.

    var locationManager : CLLocationManager!

    

    override func viewDidLoad() {

        super.viewDidLoad()

        

        locationManager = CLLocationManager()

        locationManager.delegate = self

        locationManager.requestWhenInUseAuthorization()

        locationManager.startUpdatingLocation()

        

        theMap.delegate = self

        theMap.mapType = MKMapType.standard

        theMap.showsUserLocation = true

    }

    

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

        if(!locations.isEmpty)

        {

            let myLocation = locations[0] as CLLocation

            

            theMap.setRegion(MKCoordinateRegionMake(myLocation.coordinate, MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01)), animated: true)

        }

    }

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

    }

}
