Custom Annotation View showing default pin on MKMapView - swift

Question

I'm trying to render a custom annotation view with a custom image. However I'm having trouble with the rendering of the custom annotations, as they are rendering as default map red pins as so:
I looked quite a few articles/tutorials/stack questions in regards of it but still couldn't find the problem in my code.
I created a MKPointAnnotation class
class FriendAnnotation: MKPointAnnotation {
var type: FriendModeType?
init(
coordinate: CLLocationCoordinate2D,
title: String,
subtitle: String,
type: FriendModeType
) {
super.init()
super.coordinate = coordinate
super.title = title
super.subtitle = subtitle
self.type = type
}
Then created a custom MKAnnotationView for my FriendAnnotation
class FriendAnnotationView: MKAnnotationView {
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override init(annotation: MKAnnotation?, reuseIdentifier: String?) {
super.init(annotation: annotation, reuseIdentifier: reuseIdentifier)
guard
let friendAnnotation = self.annotation as? FriendAnnotation else {
return
}
image = friendAnnotation.type?.image()
}
}
the image is then retrieved from the enum's specific function
enum FriendModeAnnotationType: Int {
//enums
func image() -> UIImage {
switch self {
case .searching:
return UIImage(imageLiteralResourceName: "trophy")
case .offering:
return UIImage(imageLiteralResourceName: "trophy")
case .none:
return UIImage(imageLiteralResourceName: "trophy")
}
}
//...
}
For testing purposes, yes it's the same image, and yes I already use the image in other parts of my code where it correctly renders
Then I created the MKMapViewDelegate for the map view
class Coordinator: NSObject, CLLocationManagerDelegate, MKMapViewDelegate {
var friendStore: FriendStore
init(friendStore: FriendStore) {
self.friendStore = friendStore
}
func mapView(
_ mapView: MKMapView,
viewFor annotation: MKAnnotation
) -> MKAnnotationView? {
print("Making the annotation view!!!")
let annotationView = FriendAnnotationView(
annotation: annotation,
reuseIdentifier: "User")
annotationView.canShowCallout = true
return annotationView
}
func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
switch manager.authorizationStatus {
//..some code
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
//...some code
}
}
And here I am with the red pin rendering instead of the trophy. As a matter of fact the print statement within the mapView function is not even getting printed, so I guess it's never calling that method
All the updates to the map correctly go through as the pins (even if just red) they actually render
Am I missing something here?

Answer 1

I figured myself that the mapView requires a delegate itself and not only the manager. So although the coordinator was inheriting both MKMapViewDelegate and CLLocationManagerDelegate I still had to set the mapView's delegate.
If anyone encounters the same problem just add the delegate to the mapView too (in my case it would be):
map.delegate = context.coordinator
This just took my entire day to figure out, so sad...
