A quick reference for AVFoundation's audio APIs in Swift, covering the essentials like audio session setup, playback, recording, and mixing options. It's the kind of cheat sheet you want open when you're wiring up audio in an iOS app and can't remember whether you need .playback or .playAndRecord, or which options let you mix with other apps. With 945 GitHub stars and 225 installs, it's clearly filling a gap for developers who work with AVFoundation regularly but don't have the API surface memorized. Solid for keeping your audio implementation clean without constantly context switching to Apple's docs.
