The Lost Art of System Design
summary
Covers three concrete system-design techniques: decomposition (split a thousand‑line podcast view controller into child view controllers, shared services like network/cache, and a podcast loader/view‑model or framework), locks and keys (use a root factory that produces a user‑bound factory after login so user‑dependent objects are non‑optional, eliminating guard/optional hacks), and abstractions (generic ListViewController with model‑loader and action‑handler types plus protocol‑based databases for easy mocking and swapping Core Data/Realm).
