Working with annotations downloaded from server on region change?

[gerchicov-bp]

You are perfect! In the example you precreated a local list of points and don't change it. But what if you have an infinite number of points and server sends you a limited annotation info based on the selected region?

You can use the delegate method func mapView(_: MKMapView, regionDidChangeAnimated _: Bool) the protocol MKMapViewDelegate provides as I understand your question correctly. Inside of the function you can then make the network request to load more pins.

Yes, you can request new annotations and use the CKClusterManager.addAnnotations(_:)
