Which SRID does Apple Maps use?

Question

The app will send the latitude and longitude to the server. It looks like it is probably NAD83 or WGS84 and I'm confused by some of the stuff I've been reading.

Answer 1

It's in the documentation! Apple's CoreLocation uses WSG84.

Answer 2

This post seems to confirm that all GPS companies use WGS84. Apple uses TOMTOM data.
