Swift Error Handling: The Solution

In our last post Swift Error Handling: The Problem , we discussed the problems with error handling in Swift. In this post, we will explore some solutions to these problems and how to implement them in your code, and we will preview my new Catcher library which provides a variety of tools following these patterns. 19|
