We will start this section with the starter project for this chapter and dive straight into code as you already are well aware of how to set up the RxSwift workspace and how to create one from scratch if need be. For the time being, open the starter project, and you will see that we have already created a SupportCode file in which we have declared an enum called CustomError, as follows:
public enum CustomError: Error { case test}
Just to verify that we are on the same page, check the following screenshot and ensure that you have a similar project structure:
We will start with the catchErrorJustReturn operator on the playground ...
