Welcome to the documentation for ReactiveCocoa, a powerful reactive programming framework for iOS and macOS applications. This documentation will guide you through the various features and functionalities provided by ReactiveCocoa, enabling you to leverage its capabilities to build responsive and interactive applications.

Getting Started

Before you start using ReactiveCocoa, it’s important to understand its basic concepts and how it integrates with your projects. Follow the steps below to get started:


ReactiveCocoa can be installed using CocoaPods or Carthage. Choose the option that suits your project best and follow the installation instructions.

Reactive Programming Concepts

ReactiveCocoa is built upon the principles of reactive programming. It’s crucial to grasp the fundamental concepts in order to effectively use ReactiveCocoa. This section provides an overview of concepts such as signals, subscribers, and transformations.

Integrating ReactiveCocoa

To integrate ReactiveCocoa into your project, you need to import the necessary frameworks and set up the dependencies. This section walks you through the steps required to correctly initialize ReactiveCocoa in your iOS or macOS application.


ReactiveCocoa offers a wide range of powerful features that simplify the development of reactive applications. Explore the following features to understand how they can enhance your projects:

Signals and Observers

Learn how to work with signals and observers in ReactiveCocoa. Signals represent reactive streams of events, while observers subscribe to these signals and respond to emitted events. Find out how to create, combine, and transform signals, as well as how to observe and react to their values.

Functional Reactive Programming (FRP)

Discover the power of functional reactive programming using ReactiveCocoa. This feature allows developers to express complex behaviors with concise and declarative code. Learn about transforming and manipulating values using map, filter, reduce, and other functional programming techniques.

User Interface Bindings

ReactiveCocoa enables bindings between user interface elements and underlying data models. Understand how to bind properties and actions in your UI to ReactiveCocoa signals, providing automatic updates and synchronization between the two.

Signals and Error Handling

Handling errors is a critical aspect of any application. ReactiveCocoa incorporates error handling mechanisms, allowing you to gracefully handle errors within your reactive chains. Learn how to handle and recover from errors using operators specifically designed for error handling scenarios.
