Answer 1

A swift4 version of Nitesh Borad Answer:

func mapView(_ map: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
    let annotationViewReuseIdentifier = "annotationViewReuseIdentifier"

    var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: annotationViewReuseIdentifier) as? MKAnnotationView

    if annotationView == nil {
        annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: annotationViewReuseIdentifier)
    }

    // here you can assign your friend's image    
    annotationView?.image = UIImage(named: "friend_image.png")
    annotationView?.annotation = annotation

    // add below line of code to enable selection on annotation view
    annotationView?.canShowCallout = true

    return annotationView
}
