This covers iOS networking migrations across three generations: BSD sockets to NWConnection, NWConnection to the new iOS 26+ NetworkConnection API, and URLSession StreamTask to NetworkConnection. It's the piece you need when Apple deprecates your networking layer and you're staring at a codebase that needs updating before the next OS drop. The skill includes concrete migration paths with code examples, handles the structured concurrency transition, and addresses the TLV framing and Coder protocol patterns that NetworkConnection introduces. If you're maintaining an app that does low-level networking and just got a deprecation warning, this maps out the path forward without the usual "rewrite everything" panic.
