Apple opens Siri AI to any app through App Intents in the 27.3 betas, and Xcode 27.3 adds GitHub Copilot

Apple says Siri AI is now open to all developers. In a developer news post on 3 November, it says that “starting today with the iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3 betas, a new Developer Preview enables any developer to integrate their app with Siri AI.”

What apps can do

The integration runs through App Intents. Apple says any app can bring “its content and actions directly into Siri AI,” which can then use its newer capabilities, “including personal context understanding, onscreen awareness, natural language, and more.” Two additions stand out for developers:

• Skills: for complex requests, Apple is “introducing skills to let you teach Siri AI how to combine several actions into a single experience.”
• Spotlight entities: “Siri AI can now surface any entity in the Spotlight semantic index, not just the ones that fit an existing schema.”

Apple says it has started rolling the same capabilities out across its own apps, including Calendar, Files, Mail, Maps, Messages, Notes, Photos, Reminders, Safari and Shortcuts, and that those actions serve as examples.

Timing and the fine print

This is early access. Apple says the preview comes “before first shipping to customers in a few months,” with “submission to the App Store opening up in the spring.” It adds that it “will follow up with more details about the terms and usage policies for experiences enabled through Siri AI. More to share soon.” Apple engineers are holding Apple Intelligence group labs on 4 and 5 November.

The footnotes set real limits:

• “Siri AI is currently unavailable in the EU in iOS, iPadOS, and watchOS. Apple is working constructively with the EU in an attempt to find a path forward.”
• “Siri AI is not available for users under 13.”
• Server-side features, “including but not limited to Siri AI,” are “subject to daily usage limits,” and “Expanded access to such features will be available for a fee in the future.”

Siri AI also needs an Apple Intelligence-enabled device set to a supported language: English, French, Japanese, Korean, Portuguese or Spanish, with Traditional Chinese, Norwegian, Turkish and Vietnamese “soon.”

Copilot in Xcode 27.3

Separately, the Xcode 27.3 beta release notes list one new Coding Intelligence feature: “GitHub Copilot is now available in the coding assistant.” The notes give no further detail on setup or which Copilot plans are supported.

Why this matters

If your app already defines App Intents, those are now the way into Siri AI, so it is worth reviewing them during the preview rather than in spring when submissions open. Plan for users who will not get it: EU iPhone users, under-13s, and anyone who hits the daily limits on server-side features, which Apple says will later cost extra. Those limits apply to requests that leave the device, the split we walked through in where an Apple Intelligence request goes, and it follows Apple’s plan to open Keynote, Pages and Numbers to outside agents over MCP.
