Creating and subscribing to Observables

In the upcoming sections, we will work with a sample project and see how can we create and subscribe to Observables in code.

As discussed earlier, we need to set up a workspace to work with RxSwift:

1. Create a single view application project and name it RxBasics.
2. Open Terminal and navigate to the project folder. Create a pod file inside your Xcode projects folder by executing the pod init command.

4. Enter the pod install command to fetch all the listed libraries from GitHub and install all of them in the project.
5. As a result of this installation, you will find a newly created...
