emitter-kit v4.0.1

 

This library provides these 5 major classes:

     Event : A type-safe event emitter.

     Signal : An event emitter that doesn't pass any data.

     Listener : An event listener!

     Notification : Backwards-compatibility with NSNotification.

     Change : Key-value observation made easy.

 

Motivation

NSNotification & NSNotificationCenter are rather verbose and fail to provide type-safety. This library aims to streamline your work with event emitters & listeners while programming with Swift. It aims to stay as simple as possible without removing powerful features.
