[IOS] The marker and the cluster do not appear

[nicolasmht]

Issue

The bug is that the marker does not appear when I zoom on the map but It only appears when the view is very zoomed out.

I changed the options and particularly the radius, tested with Google Maps, downgraded the react-native-maps lib version to that of the example, downgraded the react-native-clusterer package version to 1.2.1, but the bug still exists.

I test on a real mobile :

I think the marker coordinates are inverted, you probably inverted it at the point geometry too, it should be [lng, lat]

@benedusi Thank you for your answer ! Indeed the positions were reversed! Everything works fine now 👌
