This post is from the WWDC26 Foundation Models Q&A.
The new standalone Siri app keeps conversation history synced via iCloud across iPhone, iPad, and Mac.
- Can third-party content, results, or an app's agent surface appear inside the Siri app (e.g., as referenced sources or follow-up actions), and can the user deep-link from a Siri-app result back into the originating app with state intact?
- Is any conversation context from the Siri app exposed to a developer's intent when an action is invoked, so the app can act with the relevant context, and what are the privacy boundaries on that?
- When the same action is invoked from different surfaces (in-app, system Siri, the Siri app) and across synced devices, how should developers reason about execution location and idempotency to avoid duplicate side effects?
