Ch3

A small Swift package that exposes the H3 to Swift. SwiftH3 is probably what you want to use. This library works directly with the C functions, whereas SwiftH3 is more idiomatic Swift.

Example

# Create coordinate and get the H3 index
var coord = GeoCoord(lat: degsToRads(40.661), lon: degsToRads(-73.944))
let index = geoToH3(&coord, 10)

# Get the string representation of the index
let cString = strdup("")
h3ToString(self, cString, 17)
print("\(String(cString: cString!))")

Thanks to @s1ddok for his Cpng repo, from which I used to figure out how to build this repo.
