how to change pin color in mapkit under the same annotationview (swift3)

Subclass MKPointAnnotation to add any custom property that you want, such as a pinTintColor:

class MyPointAnnotation : MKPointAnnotation {
    var pinTintColor: UIColor?
}

class ViewController: UIViewController, MKMapViewDelegate {
    @IBOutlet var jmap: MKMapView!

    override func viewDidLoad() {
        super.viewDidLoad()

        jmap.delegate = self

        let hello = MyPointAnnotation()
        hello.coordinate = CLLocationCoordinate2D(latitude: 40, longitude: -73)
        hello.pinTintColor = .red

        let hellox = MyPointAnnotation()
        hellox.coordinate = CLLocationCoordinate2D(latitude: 34, longitude: -72)
        hellox.pinTintColor = .blue

        jmap.addAnnotation(hello)
        jmap.addAnnotation(hellox)
    }

    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
        var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "myAnnotation") as? MKPinAnnotationView

        if annotationView == nil {
            annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "myAnnotation")
        } else {
            annotationView?.annotation = annotation
        }

        if let annotation = annotation as? MyPointAnnotation {
            annotationView?.pinTintColor = annotation.pinTintColor
        }

        return annotationView
    }
}

How to change selected pin image in Map Kit in Swift 3?

"selected" means "tapped"? If so, Try the following code:

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
    view.image = UIImage(named: "marker_gray")
}

func mapView(_ mapView: MKMapView, didDeselect view: MKAnnotationView) {
    view.image = UIImage(named: "marker_red")
}
