Playground

Build

Open your terminal of choice and navigate to the repository. For our easy example we will start with Subjects. cd into that folder and RxPlayground as well.
Run the shell script bootstrap.sh from the terminal
Command to run ./bootstrap.sh
This script will download the library and appropriately bind the framework to the Playground for easy prototyping with less overhead compared to a normal xcode project.

The RxSwift library not found error No such module 'RxSwift'. Could be fixed by selecting Build Active Schemes in the project inspector ( Right side menu ).
RxRelay or Cocoa elements not building. This could be fixed by selecting the appropriate library / framework in the project build tools and first build it and then go back to the playground for clean building so this time it picks up the appropriate references.
