Swift: The Complete Guide to Error Handling in the Network Layer
In my previous article, we explored how to construct a robust, abstract network layer using Clean Architecture. The response was fantastic, but I received a recurring piece of feedback: the error handling was a bit too thin for a real-world production environment.

To provide a more granular and descriptive way of handling network events, I decided to categorize HTTP status codes into specific enums. This approach ensures that our logic is both type-safe and highly readable. By referencing the MDN Web Docs, I mapped out each response category to its own structure.
