mapViewDidChangeVisibleRegion

Using Swift

Any help with this?
Hi there, can you tell me why mapViewDidChangeVisibleRegion does not update when this is run? it doesn't print anything when I move map around. I get this message: MobileGestalt.c:1647: Could not retrieve region info

struct MapView: UIViewRepresentable {

class Coordinator: NSObject, MKMapViewDelegate {
    var parent: MapView
    
    init(_ parent: MapView) {
        self.parent = parent }
}

func **mapViewDidChangeVisibleRegion**(_ mapView: MKMapView) {
    print(mapView.centerCoordinate)
}

This looks more like a question about 3rd party framework (specifically MapKit). I'd suggest that you post it over https://forums.developer.apple.com/ instead.

You don't seem to have assigned parent's delegate, so you won't receive delegate callbacks.
