You should check the Apple Documentation for which method you should call.
Go there and search for: CLLocationManager - then look at it’s properties - one of them is: distanceFilter. Having a read of that - we should be able to implement the code needed.
Change your implementation to:
Run your app in the simulator and when you simulate another country it will update.
What I did to make sure it’s working was first set the distance filter to like 500000 meters and then simulated moving between two countries that were closer than that together - I got no update (As expected)
I then changed it back to 50 meters and did the above, again - updates were coming in now (As expected)
