While the showsUserLocation property is true, the map view calls this method whenever it receives a new location update. It also calls this method if the map view’s user-tracking mode is MKUserTrackingMode.followWithHeading and the heading changes.
The.map view doesn’t call this method if the app is running in the background. If you want to receive location updates while running in the background, use the Core Location framework.
