Adjusting Size of Apple MKMapView Labels

Question

The map view in my app works well all round, and appears correctly on iPads. But on iPhones, the country/state/city/etc. labels appear extremely large and oversized. Here's a screenshot of how it looks on iPhone 8 Plus:

The width of the map view is almost maximum, close to the width of the screen.

Q: Is there any way to adjust/reduce those label font sizes?

Answer 1

According to Apple Dev support, edford, the labels in MKMapView directly correlate to the text size settings on the device. There is no API to control this through code, as it is a user preference setting.
