SiriKit encompasses the Intents and Intents UI frameworks, which you use to implement app extensions that integrate your services with Siri and Maps. SiriKit supports two types of app extensions:
An Intents app extension receives user requests from SiriKit and turns them into app-specific actions. For example, the user might ask Siri to send a message, book a ride, or start a workout using your app.
An Intents UI app extension displays branding or other customized content in the Siri or Maps interface after your Intents app extension fulfills a user request. Creation of this extension is optional.
SiriKit defines the types of requests—known as intents—that users can make. Domains group related intents to make it clear which intents you might support in your app. For example, the messages domain has intents for sending messages, searching for messages, and marking messages as read or unread.
Your app extensions rarely communicate with the user directly. Siri and Maps typically handle all communication with the user and call out to your extensions only when they need you to provide information. You can provide an Intents UI app extension to customize the information that Siri and Maps display, but doing so is optional.
