A Swift Playground focused on the creation and use of Geohashes. According to Wikipedia a Geohash is
a hierarchical spatial data structure which subdivides space into buckets of grid shape
Add the two files Geohash.swift and Base32Format.swift files into your project.
let latitude = 57.64911
let longitude = 10.40744
let geohash = try Geohash(latitude: latitude, longitude: longitude, format: format, precision: 11)Geohashing provides a shorter and simpler way to respresent geographic coordinates.
let geohashString = geohash.hashString // u4pruydqqvj vs 57.64911,10.40744
