Mapbox's earcut.js is governed by an ISC license while this Swift port is governed by an MIT license.
Add the following dependency
.package(url: "https://github.com/measuredweighed/SwiftEarcut.git", from: "2.2.4"),Comprehensive documentation for SwiftEarcut can be found on the Swift Package Index (click on Documentation).
Pass Earcut a flat array of vertex coordinates and optionally include an array of hole indices, and the tesselate function will return a flat array of triangle indices.
let result = Earcut.tesselate(data: [10, 0, 0, 50, 60, 60, 70, 10])
// result: [1, 0, 3, 3, 2, 1]
