Adding Pins to Map using MapKit - Swift 3.0

Question

New coder, trying to figure out how to use MapKit. The goal is to create a map that users can add pins to using their address. However, the step I am at now, I am having trouble figuring out how to add pins to the map at all.

How can I add a pin to the map? I have been struggling to figure out how to use annotations thus far.

That's what I'm hoping for help/direction with. Thanks!

import UIKit import MapKit import CoreLocation  class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate  {     @IBOutlet weak var bigMap: MKMapView!      let locationManager = CLLocationManager()      override func viewDidLoad() {         super.viewDidLoad()         self.locationManager.delegate = self         self.locationManager.desiredAccuracy = kCLLocationAccuracyBest         self.locationManager.requestWhenInUseAuthorization()         self.locationManager.startUpdatingLocation()         self.bigMap.showsUserLocation = true      }      override func didReceiveMemoryWarning() {         super.didReceiveMemoryWarning()     }      func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {         let location = locations.last         let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)         let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.02, longitudeDelta: 0.02))          self.bigMap.setRegion(region, animated: true)         self.locationManager.stopUpdatingLocation()      }      func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {         print("Errors " + error.localizedDescription)     } }

They're called annotations in the MapKit and you should instantiate them like so:

let annotation = MKPointAnnotation()  

then in the viewDidLoad() method just set the coordinates and add them to the map like:

annotation.coordinate = CLLocationCoordinate2D(latitude: 11.12, longitude: 12.11) mapView.addAnnotation(annotation) 

The numbers are your coordinates
