Booking a Ride with SiriKit
At the WWDC conference in 2016, Apple announced SiriKit, which enables developers to provide functionality that can be executed directly from Siri, without opening the main application. This is another step to the idea of using new, innovative ways to interact with users via conversational interfaces, simplifying the whole user experience. Your app can now provide functionality to Siri directly from the lock screen and when the app is not even started. However, as is usually the case with Apple, there are some limitations. You can use SiriKit only for certain predefined domains.
