Image annotation different - xcode

Question

I created a map view with different annotation and a search. I can not attribute a different image according to the pin. I also have another concern, when I do a search it removes a pin to put it on the new place sought. Below is the code of a young coder. In advance thank you for your help.
import MapKit
import UIKit
import CoreLocation
class MapViewController: UIViewController, UISearchBarDelegate, MKMapViewDelegate {
#IBOutlet weak var MapView: MKMapView!
var searchController:UISearchController!
var annotation:MKAnnotation!
var localSearchRequest:MKLocalSearchRequest!
var localSearch:MKLocalSearch!
var localSearchResponse:MKLocalSearchResponse!
var error:NSError!
var pointAnnotation:MKPointAnnotation!
var pinAnnotationView:MKPinAnnotationView!
var coordinates: [[Double]]!
var name:[String]!
let regionRadius: CLLocationDistance = 1000
#IBAction func showSearchBar(_ sender: Any) {
searchController = UISearchController(searchResultsController: nil)
searchController.hidesNavigationBarDuringPresentation = false
self.searchController.searchBar.delegate = self
present(searchController, animated: true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
self.MapView.delegate = self
var Tirta = CustomPointAnnotation()
Tirta.coordinate = CLLocationCoordinate2DMake(-8.415162, 115.315360)
Tirta.title = "Tirta Empul"
Tirta.imageName = "PaConseil.png"
var Goa = CustomPointAnnotation()
Goa.coordinate = CLLocationCoordinate2DMake(-8.551313, 115.468865)
Goa.title = "Goa Lawah"
Goa.imageName = "PaMecontent.png"
MapView.addAnnotation(Tirta)
MapView.addAnnotation(Goa)
// 3
let region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: -8.670458199999999, longitude: 115.2126293), span: MKCoordinateSpan(latitudeDelta: 2, longitudeDelta: 2))
self.MapView.setRegion(region, animated: true)
}
func MapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
print("delegate called")
if !(annotation is CustomPointAnnotation) {
return nil
}
let reuseId = "test"
var AnnotationView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId)
if AnnotationView == nil {
AnnotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
AnnotationView?.canShowCallout = true
}
else {
AnnotationView?.annotation = annotation
}
func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
let CustomPointAnnotation = annotation as! CustomPointAnnotation
AnnotationView?.image = UIImage(named:CustomPointAnnotation.imageName)
return AnnotationView
}
class CustomPointAnnotation: MKPointAnnotation {
var imageName: String!
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar){
//1
searchBar.resignFirstResponder()
dismiss(animated: true, completion: nil)
if self.MapView.annotations.count != 0{
annotation = self.MapView.annotations[0]
self.MapView.removeAnnotation(annotation)
}
//2
localSearchRequest = MKLocalSearchRequest()
localSearchRequest.naturalLanguageQuery = searchBar.text
localSearch = MKLocalSearch(request: localSearchRequest)
localSearch.start { (localSearchResponse, error) -> Void in
if localSearchResponse == nil{
let alertController = UIAlertController(title: nil, message: "Place Not Found", preferredStyle: UIAlertControllerStyle.alert)
alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.default, handler: nil))
self.present(alertController, animated: true, completion: nil)
return
}
//3
self.pointAnnotation = MKPointAnnotation()
self.pointAnnotation.title = searchBar.text
self.pointAnnotation.coordinate = CLLocationCoordinate2D(latitude: localSearchResponse!.boundingRegion.center.latitude, longitude: localSearchResponse!.boundingRegion.center.longitude)
self.pinAnnotationView = MKPinAnnotationView(annotation: self.pointAnnotation, reuseIdentifier: nil)
self.MapView.centerCoordinate = self.pointAnnotation.coordinate
self.MapView.addAnnotation(self.pinAnnotationView.annotation!)
}
}
}
import Foundation
import MapKit
class CustomPointAnnotation: MKPointAnnotation {

var imageName: UIImage!
init(coordinates: CLLocationCoordinate2D) {
self.coordinates = coordinates
}
}

I'm going to assume that you've updated Xcode so that you are now using Swift 3. Well then, the problem is that this method is never being executed:
func MapView(mapView: MKMapView!,
viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
... and the reason is that that is not its correct "signature". That method is now defined like this:
func mapView(_ mapView: MKMapView,
viewFor annotation: MKAnnotation) -> MKAnnotationView?
