Notifies the handler when its feature session ends.
Declaration
func sessionInvalidated(error: (any Error)?)Parameters
- error:
An optional error that indicates why the session ends. A
nilvalue indicates ordinary completion.

The framework throws AccessoryTransportSession.Error.unavailable if the device loses feature eligibility as the session runs. Release any references to the session when the system calls this method.
