Hi everyone — I’m implementing the new Hearing Device Support API described here: https://developer.apple.com/documentation/accessibility/hearing-device-support I have MFi hearing aids paired and visible under Settings → Accessibility → Hearing Devices, and I’ve added the com.apple.developer.hearing.aid.app entitlement (and also tested with Wireless Accessory Configuration: https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.external-accessory.wireless-configuration ). com.apple.developer.hearing.aid.app xxxxx but the app won't even compile with this entitlement Problem NotificationCenter.default.addObserver(...) for pairedUUIDsDidChangeNotification never fires — not on app launch, not after pairing/unpairing, and not after reconnecting the hearing aids. Because the notification never triggers, calls like: HearingDeviceSession.shared.pairedDevices always return an empty list. What I expected According to the docs, the notification should be posted whenever paired device UUIDs change, and the session should expose those devices — but nothing happens. Questions Does the hearing.aid.app entitlement require special approval from Apple beyond adding it to the entitlements file? Is there a way to verify that iOS is actually honoring this entitlement? Has anyone successfully received this notification on a real device? Any help or confirmation would be greatly appreciated.
