# App Schemas integration for Siri AI > Source-anchored research for App Schemas integration for Siri AI. Run status: COMPLETED. Parent: [Apple Intelligence](https://llms-explorer.com/tree/apple-intelligence/) · 3 facets · 15 facts · page: https://llms-explorer.com/tree/app-schemas-integration-for-siri-ai/ ## Structure and components - Apple defines App Schemas as system-defined contracts for app intents, entities, and enums. Developers attach them with `AppIntent(schema:)`, `AppEntity(schema:)`, or `AppEnum(schema:)`; the selected schema tells the system how to interpret that type and its supported structure. (high confidence) — [source](https://developer.apple.com/documentation/appintents/app-schema-domains.md) - Some App Schema use-case groups need the full related set for a complete Siri flow. Apple says Xcode warns when an app adopts only part of a group, such as adopting `sendMessage` without the related `draftMessage` schema; treat these diagnostics as integration guidance and verify the full supported flow. (high confidence) — [source](https://developer.apple.com/documentation/appintents/making-actions-and-content-discoverable-by-apple-intelligence) - Validate the integration in layers: use AppIntentsTesting for intent execution, results, entity queries, and system integrations; use Shortcuts to inspect intent configuration; check entity discovery in Spotlight; then test the complete request path in Siri. Apple describes AppIntentsTesting as running through the App Intents stack without UI automation. (high confidence) — [source](https://developer.apple.com/videos/play/wwdc2026/240/) ## How it works - Choose schemas that match the app’s actual functionality. Apple says new Siri AI integration requires an app to adopt at least one App Schema, while custom AppIntents and AppShortcuts can coexist for actions outside the predefined schemas. Apple identifies the generic `system.search` schema as an option when an app’s search flow has no closer domain match. (high confidence) — [source](https://developer.apple.com/videos/play/wwdc2026/8011/) - A developer in a Reddit beta discussion reported that Siri AI could describe custom app entities and open them with `.system.open`, but could not take other actions on those entities because they did not fit predefined schemas. The developer also reported inconsistent invocation of existing App Intents. This is one developer’s beta report, not evidence of final or general platform behavior. (low confidence) (verified as of 2026-10-23) — [source](https://www.reddit.com/r/Siri/comments/1ukbfe0/app_intents/) - Apple defines system schemas for AppIntent, AppEntity, and AppEnum types and maps a type to its selected schema with the AppIntent(schema:), AppEntity(schema:), or AppEnum(schema:) macro. Apple also recommends adopting optional schemas because they increase the number of actions people can invoke with Apple Intelligence and Siri. (high confidence) — [source](https://developer.apple.com/documentation/appintents/app-schema-domains.md) - Apple's WWDC26 implementation walkthrough shows Xcode surfacing a missing companion schema at build time, with a Fix-It, and recommends testing an intent with AppIntentsTesting in isolation before checking the complete flow through Shortcuts, Spotlight, and Siri. (medium confidence) — [source](https://developer.apple.com/videos/play/wwdc2026/240/) ## Facts and statements - Model app content as schema-backed AppEntity types and supported operations as schema-backed AppIntent types. Apple’s calendar sample maps calendar, attendee, and event entities plus create, update, delete, and open actions to the calendar and system domains, allowing Siri to resolve app-specific content and invoke matching actions without app-authored natural-language parsing. (high confidence) — [source](https://developer.apple.com/videos/play/wwdc2026/240/) - The OS 27 release notes identify schema conformance changes: `calendar.deleteEvents` was renamed to `calendar.deleteEvent`, and existing `.photos.asset` conformances may need added properties and availability checks. Rebuild against the OS 27 SDK and resolve schema diagnostics before relying on an older conformance. (medium confidence) (verified as of 2026-09-14) — [source](https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-27-release-notes) - Apple Support’s October 22, 2026 availability page labels Siri AI as beta and lists OS 27, Apple Intelligence-capable hardware, a matching supported device and Siri language, and an eligible Apple Account region as requirements; activation may include a waitlist. The page also lists platform-specific EU limits and no current availability for Apple Accounts in mainland China. This implies that schema adoption alone does not guarantee that a particular tester can exercise Siri AI end to end. (low confidence) (verified as of 2026-10-22) — [source](https://support.apple.com/en-us/127893) - 9to5Mac reported on July 7, 2026 that Siri AI in iOS 27 beta 3 retrieved vehicle battery information from Tessie and a Ford app in its observed examples, while the official Tesla app did not work in those tests. This is a dated beta observation and does not establish which App Schemas each app adopted. (low confidence) (verified as of 2026-07-07) — [source](https://9to5mac.com/2026/07/07/siri-ai-can-pull-info-from-third-party-apps-in-the-latest-developer-beta/) - An AppEntity describes existing app content for the system, while an entity schema tells Siri what category that content represents. An AppIntent schema provides a known action shape and parameters; the app maps those parameters to its own behavior and returns the result, such as the Messages sendMessage example returning the sent message as an entity. (high confidence) — [source](https://developer.apple.com/documentation/appintents/app-schema-domains) - Apple distinguishes general App Intent availability across surfaces such as Shortcuts, Spotlight, and Widgets from schema-shaped actions that Siri can execute through natural language; schema domains group related contracts such as Messages, Mail, and Photos. (high confidence) — [source](https://developer.apple.com/documentation/appintents/making-actions-and-content-discoverable-by-apple-intelligence) - Apple's support page published October 22, 2026 lists Siri AI as a beta and gates access on supported hardware, a supported device and Siri language, an eligible region, and joining a waitlist; schema adoption alone does not guarantee that a given user can run Siri AI. (low confidence) (verified as of 2026-10-22) — [source](https://support.apple.com/en-us/127893) - On July 7, 2026, 9to5Mac reported that iOS 27 beta 3 Siri AI could retrieve vehicle data from some third-party apps, including Tessie and Ford, while a reporter's vehicle test and the native Tesla app did not work; this is a limited beta observation and does not establish coverage across apps or identify each app's schema implementation.
