## Discussion

Discussion When SiriKit launches your app, it fills this property with the intent and response information that are the reason for launching your app. Use the information in this property to configure your app’s interface and show any relevant interaction details. If your app wasn’t launched because of a Siri interaction, the value in this property is nil.
