Aftermath

Aftermath is a stateless message-driven micro-framework in Swift, which is based on the concept of the unidirectional data flow architecture.

At first sight Aftermath may seem to be just a type-safe implementation of the publish-subscribe messaging pattern, but actually it could be considered as a distinct mental model in application design, different from familiar MVC, MVVM or MVP approaches. Utilizing the ideas behind Event Sourcing and Flux patterns it helps to separate concerns, reduce code dependencies and make data flow more predictable.
