Apple Opens Siri AI to All Developers in iOS 27.3 Beta

Opening Siri AI to third‑party apps via App Intents gives developers early testing access, signaling a staged rollout with a public release set for December.

An iPhone and gold Apple Watch show a Recaps app. The phone displays an AI summary, "Personal Training Routine," with a three-day workout structure and next steps. The watch lists Personal Training Routine and Easy Wellness Habits.

Overview

  • Apple began seeding the first developer betas for iOS 27.3, iPadOS 27.3, macOS 27.3, watchOS 27.3 and visionOS 27.3 on Tuesday, giving registered developers immediate access to the new preview builds.
  • A Developer Preview in those betas lets any developer expose app content and custom actions to Siri AI using App Intents, but integrations can run only in development‑signed builds and internal TestFlight for now.
  • iOS 27.3 expands Siri so it can act inside many built‑in apps with concrete tasks such as unsubscribing in Mail, scheduling or unsending Messages, organizing Files, creating Calendar events with invitees and sorting Safari tabs by voice.
  • watchOS 27.3 adds Audio Intelligence features Live Rewind and Siri Recap that require the latest Apple Watch models and iOS 27.3, with Apple saying audio is processed on device and unsaved summaries are auto‑deleted.
  • The beta also restores the redesigned Health app, adds Safari vertical tabs and adaptive dark mode, brings StandBy and Reachability refinements, and enables a limited set of Apple Intelligence tools in China under local controls.
