PointCompression

A compression algorithm to encodes/decodes a collection of CLLocationCoordinate2D into a string. check out the post: microsoft.com.

Requirements

Swift 5 and beyond.

Usage

import CoreLocation
import PointCompression

extension CLLocationCoordinate2D {
    static func random() -> CLLocationCoordinate2D {
        return CLLocationCoordinate2D(latitude: Double(arc4random_uniform(140)) * 0.00001,
                                      longitude: Double(arc4random_uniform(140)) * 0.00001)
    }
}

func main() {
    var coordinates = [CLLocationCoordinate2D]()

    for _ in 0...3000 {
        coordinates.append(.random())
    }

    let stringValue = PointCompression.Encode(coordinates)
    let decodedCoordinates = PointCompression.Decode(stringValue)
}
