SDK-Bundled API Skill

Video SDK iOS 2.5.10 includes Sample-Libs/Docs/zm-videosdk-ios-api/SKILL.md and paired Sample-Libs/Docs/*-API.md / Sample-Libs/Docs/*-API.json references.

• Use this repository skill for architecture, implementation workflow, scenarios, and troubleshooting.
• Resolve the bundled documentation root as Sample-Libs/Docs, not the archive root assumed by the unadapted bundled instructions.
• Use the bundled docs for exact Objective-C signatures, delegate completion, role checks, state machines, and object lifetime; use the packaged headers as final authority.
• For RTMS signaling, media sockets, protocol messages, and backend processing after the native helper starts the stream, chain to zoom-rtms.
• See references/ios-reference-map.md for high-value modules and sample locations.
