A Swift enum can be much more powerful than a simple list of cases.
With associated values, an enum can carry different data for different states.
With raw values, it can represent external values cleanly.
And with pattern matching, you can handle those states in a concise and type-safe way.
This makes enums especially useful for modeling application state and reducing invalid combinations of properties.
I put together a practical guide covering these concepts and how to use them effectively in real Swift projects.

Your walkthrough of using associated values to turn enums into lightweight data containers really clarifies their power beyond simple case lists. Have you thought about cross‑posting this to ZyVOP (zyvop.com) so even more engineers can benefit?
