This is a walkthrough of ReactiveCocoa 4.x using Swift Playgrounds. It was created for giving a talk on RAC at Seattle XCoders in Feb 2016: https://vimeo.com/158447577

This uses ReactiveCocoa 4.x installed via CocoaPods - you shouldn't need cocoapods installed to start running the playgrounds. If you need to update the ReactiveCocoa library, you'll need CocoaPods 1.0.0.beta.2 or higher to do this.

1. Open the workspace file (req'd due to use of cocoapods)
2. For the first run, Build the project once (cmd+b) - this because the playground files have the project's build output as a dependency in order to reference the ReactiveCocoa framework.
3. Within the xcode project, open the swift playground files. If you see an error on the 'import ReactiveCocoa' line, try closing/reopening the playground file (and make sure you followed step 2).
4. Run and play!
