Do you have professional experience with systems or APIs related to mapping or maps?

Yes, in professional iOS development, working with mapping services and APIs such as MapKit, Google Maps SDK, and others is common.

For example, MapKit allows displaying maps, adding annotations (pins), building routes, tracking user location, and interacting with geodata.

An example of using MapKit to display a map and add a pin:

import MapKit

let mapView = MKMapView(frame: view.bounds)
view.addSubview(mapView)

let annotation = MKPointAnnotation()
annotation.coordinate = CLLocationCoordinate2D(latitude: 55.751244, longitude: 37.618423) // Moscow
annotation.title = "Moscow"
mapView.addAnnotation(annotation)

mapView.setRegion(MKCoordinateRegion(center: annotation.coordinate,
                                     span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05)),
                  animated: true)

Experience may also include integration with external APIs for geocoding, routing, working with custom layers, etc.
