README
SwiftSimplify is a tiny high-performance Swift polyline simplification library ported from Javascript's Simplify.js. Original work come from Leaflet, a JS interactive maps library by Vladimir Agafonkin.
It uses a combination of Douglas-Peucker and Radial Distance algorithms. Works both on browser and server platforms.
★★ Star our github repository to help us! ★★
Why
Polyline simplification dramatically reduces the number of points in a polyline while retaining its shape, giving a huge performance boost when processing it and also reducing visual noise. For example, it's essential when rendering a 70k-points line chart or a map route in the browser using MapKit.

Installation
SwiftSimplify is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "SwiftSimplify"
Usage
Usage is pretty straightforward: in fact you need just call the SwiftSimplify's class method simplify by passing your configuration:
let allPoints: [Point2DRepresentable] = ...
let simplifiedPoints = SwiftSimplify.simplify(allPoints, tolerance: tolerance)
Allowed parameters are:
points: An array of points. SwiftSimplify supports Swift's generic so you can pass an array of objects which are conforms toPoint2DRepresentableprotocol (bothCGPointandCLLocationCoordinate2Dobjects supports it).tolerance: (1 by default) Affects the amount of simplification (in the same metric as the point coordinates)highQuality: (false by default) Excludes distance-based preprocessing step which leads to highest quality simplification but runs ~10-20 times slower.
