Apple Opens Siri AI to All Developers: iOS 27.3 Betas Add a Developer Preview for App Intents and Multi-Step Skills
On November 3, Apple announced on its Developer site that a new Developer Preview in the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas lets any app bring its content and actions into Siri AI through App Intents, tapping personal context, onscreen awareness and natural language. Apple also introduced skills, which teach Siri AI to combine several actions into one experience, and Siri AI can now surface any entity in the Spotlight semantic index. It is a preview only: customer rollout is a few months away and App Store submissions open in spring. Siri AI remains unavailable in the EU on iOS, iPadOS and watchOS.
