Burst 🎆

Burst is a Swift and simple way to make elements in your iOS app burst.

Back in the day, Facebook Paper popularized a firework burst effect using CAEmitterLayers with buttons.

This library provides a firework effect using CAEmitterLayers contained in an easy-to-use customizable component, written in Swift.

If you enjoy this library, you may also like another CAEmitterLayer project, Twinkle.
