Description

--- name: swift-avfoundation-playback description: Fundamentals-first Swift AVFoundation playback guidance for AVAsset/AVPlayerItem/AVPlayer, seeking timelines, observation, queueing, AirPlay, audio session, PiP, HLS, DRM, ads, and diagnostics across Apple platforms. Use when implementing or reviewing playback behavior. --- # Swift AVFoundation Playback Skill Use this skill to build playback behavior from a stable fundamentals core, then load only the topic files you need. ## Read Order 1. `references/player-item-lifecycle.md` 2. `references/seeking-and-timelines.md` 3. `references/observable-setup.md` 4. `references/time-observation.md` 5. `references/intent-tracking.md` ## Topic Map - Queue and transitions: `references/queue-playback.md`, `references/gapless-playback.md`, `references/coordinated-playback.md` - System integrations: `references/airplay-routing.md`, `references/audio-session.md`, `references/now-playing.md`, `references/picture-in-picture.md`, `references/platform-patterns.md` - Streaming and reliability: `references/hls-streaming.md`, `references/stall-recovery.md`, `references/error-handling.md` - Protected and monetized playback: `references/fairplay-drm.md`, `references/ad-insertion.md` ## Policy Rules - Treat AVFoundation transport properties as signals into your app state machine. - Keep UI mutation on the main actor. - If Apple documentation does not guarantee a behavior, express it as app policy. Sources: - https://developer.apple.com/documentation/avfoundation/avplayer — Defines the core transport API used throughout this skill. - https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/AVFoundationPG/Articles/02_Playback.html — Defines playback object relationships and readiness concepts. - https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/MediaPlaybackGuide/Contents/Resources/en.lproj/Introduction/Introduction.html — Provides Apple’s conceptual structure for media playback fundamentals.
