Audioaccessorykit

For companion apps that need to integrate third-party audio accessories with iOS's automatic audio routing. You pair the device via AccessorySetupKit first, then use this to register capabilities like audio switching and placement tracking. The system can then intelligently route audio based on whether headphones are on the user's head or sitting on a desk. You push updates through AccessoryControlDevice whenever placement changes or when your accessory connects to multiple Bluetooth sources. Only available in iOS 26.4+, so it's beta-sensitive and APIs may shift before GM. Most useful if you're building a companion app for Bluetooth headphones or earbuds that want first-class iOS integration rather than generic Bluetooth behavior.
