This is essentially a comprehensive networking playbook for iOS development that forces you to consult proper patterns instead of rolling your own broken implementations. It covers URLSession with structured concurrency, Network.framework (both the new iOS 26+ NetworkConnection and legacy NWConnection), and systematic debugging for connection failures. The pressure resistance section is notable because it explicitly tells Claude not to validate your custom networking layer just because you spent time on it. Includes migration guides from BSD sockets and URLSession StreamTask, plus an automated auditor agent for catching deprecated APIs before App Store rejection. If you're doing any network calls, WebSockets, or TCP connections in Swift, this keeps you from reinventing wheels badly.
