Open-source alternatives to ReactorKit

A publish/subscribe EventBus optimized for iOS

Bond is a Swift data binding framework designed to synchronize data models and user interface elements through one-way and two-way value flows. It functions as a reactive suite for monitoring collection changes, transforming data streams, and bridging user interface events to data models. The project provides a reactive bridge that transforms user interface interactions and protocol delegate method calls into observable signals. It includes a collection observer to monitor changes in arrays and a functional data stream processor that applies operators to modify or combine values before they r

A simple, header only event bus library written in modern C++17.

Small header only library to call a function at a specific time interval.

A Swift based Future/Promises Library for IOS and OS X.

📬 A lightweight implementation of an observable sequence that you can subscribe to.

Get the first event in a set of event emitters and event pairs, then clean up after itself.

Views as functions of their state.

Lightweight Promises for Swift & Obj-C

NoticeObserveKit is type-safe NotificationCenter wrapper.

Publish–subscribe design pattern implementation framework, with an ability to publish events by topic.

PromiseKit is a future-based concurrency framework and promise library for Swift and Objective-C. It functions as an asynchronous workflow coordinator, representing the eventual result of an operation to simplify concurrency logic and replace nested callback structures. The framework enables the coordination of both sequential and parallel asynchronous tasks. It provides a structured pipeline for chaining operations, allowing the results of one task to be passed into the next and facilitating the execution of multiple operations simultaneously. The library includes a state-machine based reso

UI event handling using Apple's combine framework.

Open source implementation of Apple's Combine framework for processing values over time.

Modern thread-safe and type-safe key-value observing for Swift and Objective-C

EventEmitter3 is a high-performance JavaScript event emitter and publish-subscribe library. It implements the observer pattern to enable decoupled communication between application components through the registration and emission of custom events. The library functions as a context-aware event dispatcher, allowing specific execution contexts to be bound to listeners. This removes the need for manual function binding during event dispatching. The project covers core event management capabilities, including listener registration and a synchronous execution loop for event delivery. It utilizes

:recycle: Unidirectional State Management Architecture for Swift - Inspired by Vuex and Flux

ReactiveCocoa is a functional reactive programming framework and Cocoa UI binding layer. It provides a library for composing asynchronous data streams and managing application state through signals and functional operators. The framework functions as an Objective-C data binding library that links object properties and method calls to reactive streams using runtime dynamism and swizzling. It includes a utility to convert traditional key-value observation notifications into composable streams for synchronized state tracking. The project covers reactive UI programming by connecting interface el

RxSwift is a reactive programming library for Swift that provides a framework for managing push-based data flows and composing asynchronous, event-based programs. It utilizes observable sequences and functional operators to transform and filter asynchronous sequences through a declarative approach. The library is distinguished by its ability to link asynchronous data streams directly to user interface elements, automating view updates via reactive data binding. It includes specialized tools for tracking UI control properties and events on the main thread, as well as the ability to encapsulate
