How to Automatically Display Title/Subtitle on Map Annotation (pin)

Question

I am loading an annotation onto my map view. The annotation displays as a pin when the map is loaded.

However, the title and subtitle do not appear on the pin automa

Starting in iOS 11, there is a new type of MKAnnotationView called MKMarkerAnnotationView, which can display title and subtitle without being selected. Check https://developer.apple.com/documentation/mapkit/mkmarkerannotationview

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {

    guard !(annotation is MKUserLocation) else {
        return nil
    }

    if #available(iOS 11.0, *) {
        let annoView = MKMarkerAnnotationView(annotation: annotation, reuseIdentifier: "HunterAnno")
        annoView.canShowCallout = true
        return annoView
    }

    let annoView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "HunterAnnoLow")
    annoView.canShowCallout = true
    return annoView
}
