Looks really awesome! Very quick responses. I would be interested in seeing the implementation of the service, interesting choice going with Swift. I'm guessing your using something like Vapor for hosting the API? How are the files designed? I'm guessing you have some cheap way of mapping (lat, long) into a file location? Maybe just by truncating the coordinates to your precision and mapping them onto the file? Using some fancy-pants Uber Hexagons[0]. How is the forecast delivered? Hmm! Many questions :-). I've been thinking lately of similar (but not for weather) "geographical" API's, and how to store/query data cheaply, so this interested me :-) [0]: https://github.com/uber/h3

Hexagons. There's a library available at https://github.com/uber/h3 that lets you partition the earth into hexagons (minus the required 12 pentagons) at various resolutions. It's spiffy. I had the hardest (read impossible) time when I first took a look at it getting it to compile into a mobile game. It worked fine in desktop, but not on mobile. So I punted and converted the whole thing into C#. It's a hot mess currently, but it works. However, the folks who created H3 added functionality and some optimizations that I want, so I'm rebuilding it, partly with dealing with some of the issues that have come up with my game during development. It's coming along smoothly, though the unit tests are what's slowing me down at this moment. Once that's done, I'm going back to my game. Covering the world in brightly colored hexagons as reality st
