BkTask

An asynchronous workflow library for iOS inspired by the Proactor and Reactor design patterns. It is designed with two concepts in mind, asynchronous and modular.

Doing work asynchronously allows to keep your application responsive. But parallel programming is hard. On iOS, tools like GCD and NSOperation makes it much simpler but, for complex workflows it still takes time and resources to achieve. BkTask allows you to simply run workflows in background and be notified once it is done.
