Map Kit currently only has support for reverse geocoding (coordinates to address), not forward geocoding (address to coordinates). I see another SO post mentioned this, and a few people posted their own solutions to the problem, but those answers are over a year old.
Is there still no standard solution to this (either from Apple or a robust, well-maintained library that keeps up with the APIs)? Is the best approach still to roll your own solution using the Google Maps APIs? I'd think this is a common enough problem that there would be something out there...
