iOS MapKit Tutorial: Getting Started Search Location and Directions on Mapkit

MapKit is a really useful API available on iOS devices that makes it easy to display maps, user locations with locality, and even draw routes your location to your destination.
iOS MapKit Tutorial

Getting Started User Location

Create a new project single view appplication in Swift. - MKLocationMap

Open Info.plist from the Project navigator and configure the location permission prompt message NSLocationWhenInUseUsageDescription

Add "NSLocationAlwaysAndWhenInUseUsageDescription" instead of "Privacy - Location Always and When in use usage description".

import UIKit
import MapKit

protocol HandleMapSearch {
    func dropPinZoomIn(placemark:MKPlacemark)
class ViewController: UIViewController{
    let locationManager = CLLocationManager()
    var resultSearchController:UISearchController!
    var selectedPin:MKPlacemark?
    @IBOutlet var mapView: MKMapView!
    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        let locationSearchTable = storyboard!.instantiateViewController(withIdentifier: "LocationSearchTable") as! LocationSearchTable
        locationSearchTable.mapView = mapView
        resultSearchController = UISearchController(searchResultsController: locationSearchTable)
        resultSearchController?.searchResultsUpdater = locationSearchTable
        locationSearchTable.handleMapSearchDelegate = self
        let searchBar = resultSearchController!.searchBar
        searchBar.placeholder = "Search for places"
        navigationItem.titleView = resultSearchController?.searchBar
        resultSearchController?.hidesNavigationBarDuringPresentation = false
        resultSearchController?.dimsBackgroundDuringPresentation = true
        definesPresentationContext = true
        locationSearchTable.mapView = mapView
        locationSearchTable.handleMapSearchDelegate = self
    @objc func getDirections(){
        guard let selectedPin = selectedPin else {
        let mapItem = MKMapItem(placemark: selectedPin)
        let launchOptions = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
        mapItem.openInMaps(launchOptions: launchOptions)
        print ("GET DIRECTION")
    override func didReceiveMemoryWarning() {
        // Dispose of any resources that can be recreated.
extension ViewController : CLLocationManagerDelegate {
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("error:: \(error.localizedDescription)")
 func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status == .authorizedWhenInUse {
  func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.first {
            let span = MKCoordinateSpanMake(0.05, 0.05)
            let region = MKCoordinateRegion(center: location.coordinate, span: span)
            mapView.setRegion(region, animated: true)
extension ViewController: HandleMapSearch {
    func dropPinZoomIn(placemark:MKPlacemark){
        // cache the pin
        selectedPin = placemark
        // clear existing pins
        let annotation = MKPointAnnotation()
        annotation.coordinate = placemark.coordinate
        annotation.title =
        if let city = placemark.locality,
           let state = placemark.administrativeArea {

        let span = MKCoordinateSpanMake(0.05, 0.05)
        let region = MKCoordinateRegionMake(placemark.coordinate, span)
        mapView.setRegion(region, animated: true)

In the Project Navigator, open Assets.xcassets and create a add image icon like used car.png files of various sizes (30×30, 60×60, and 90×90) to fill up the 1x, 2x, and 3x

extension ViewController : MKMapViewDelegate {
    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView?{

            //return nil so map view draws "blue dot" for standard user location
            return nil
        let reuseId = "pin"
        var pinView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId) as? MKPinAnnotationView
        if pinView == nil {
        pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
        pinView?.pinTintColor =
        pinView?.canShowCallout = true
        let smallSquare = CGSize(width: 30, height: 30)
        let button = UIButton(frame: CGRect(origin:, size: smallSquare))
        button.setBackgroundImage(UIImage(named: "car"), for: .normal)
        button.addTarget(self, action: #selector(ViewController.getDirections), for: .touchUpInside)
        pinView?.leftCalloutAccessoryView = button
