Roll your own networking stack
summary
Refactors a massive view controller into a tiny composable networking layer built in Swift using URLSession. Claims simple cases stay easy while hard cases remain possible by using a Requestable protocol to hold path and headers, a Resource<T> generic that carries a decode closure, and an APIClient with Environment that supplies baseURL and common headers. Shows a JSONDecoder keypath helper, default protocol implementations, and says the whole stack fits in ~100–150 lines and makes networking testable and concise.
