ReactiveCocoa (RAC) is a framework for composing and transforming sequences of values.

No seriously, what is it?

Check out the announcement blog post for a ton more info.

Getting Started

RAC uses some submodules. Once you've cloned the repository, be sure to run git submodule update --recursive --init to pull them all down.

Then checkout the Mac or iOS demos.

Foundation Support

There are a number of categories that provide RAC-based bridges to standard Foundation classes. They're not included as part of the framework proper in order to keep the framework size down.

You can find them in RACExtensions. To use them, simply add them directly to your project as needed.


Fork this repository, make it awesomer (preferably in a branch named for the topic), send a pull request!
