Swift + IoT + HVAC

I've been exploring IoT the last week or so and just wrote an article on building a custom sensor / relay prototype for my new HVAC system I'm experimenting with. One of my goals is to also utilize swift as much as possible during my exploration of IoT and embedded systems. If anyone has any resources of how to run swift on ESP-32 devices that would be awesome.

At any rate, while this was my first experiment / code (it can surely be improved) here is my article if it's helpful to anyone.
