## Discussion

Discussion Use this method if you previously set the picker display setting discoveryTimeout to unbounded in order to perform manual filtering of discovered accessories. Calling this method finishes the discovery session in the picker and shows a timeout error if the session didn’t find any desired accessories. Calling this method after updating the picker with discovered accessories has no effect.
