Apple Opens iOS and watchOS 27.3 Betas as Siri Plans Expand

Apple began its 27.3 software testing cycle on November 3 with developer betas for iOS, iPadOS, macOS and watchOS. The iPhone update includes a redesigned Health app and a vertical tabs option in Safari, according to Thurrott.com.

The broader change is Siri's ability to work with apps. The Next Web reported that Apple opened a developer preview allowing any app developer to bring content and actions into Siri AI, with support in the iOS, iPadOS, macOS and visionOS 27.3 betas.

The first beta also started spreading features previously associated with the iPhone Duo. On November 3, Digital Trends reported that new StandBy clocks, Calendar and Weather faces were reaching other iPhones.

On November 4, The Hindu reported that Siri AI was gaining more complex tasks across Calendar, Mail, Notes and Photos. Separately, MacRumors reported that the Xcode 27.3 beta gave developers a way to test Siri AI integration in their apps.

The Apple Watch changes brought conversation summaries into the update, according to MacRumors. An early hands-on account from TechCrunch, published November 4, described Siri Recaps as useful while raising privacy reservations and identifying room for improvement.

Public testing opened on November 5. MacRumors reported that Apple released public betas for iOS, iPadOS, macOS Golden Gate, tvOS and watchOS 27.3, two days after the developer releases. AppleInsider reported encountering bugs and incompatibilities in the new software.

Access to Siri AI also became easier. On November 5, Business Insider reported that Apple had largely dropped the waitlist, keeping it only for periods of high demand.

The software is available for public beta testing, not yet as a finished general release. Beyond Siri, the changes include Health's redesign, Safari's vertical tabs and Apple Music's Selfie Sing feature, which lets users record themselves singing while lyrics remain onscreen, according to Digital Trends.

The distinction between developer access and finished Siri capabilities matters. Earlier coverage described a broad opening of app integration, but AppleInsider reported on November 8 that more control over Apple apps would not arrive until spring 2027. Developers can already test some tasks, but that does not mean the full expansion is ready.

IosMac reports that iOS 27.3 is due in December. The immediate question is which Siri actions will be ready for that release, and which will remain part of the longer development schedule.

A separate push could take Siri further. The Verge reported on November 8 that CEO John Ternus is pressing AI czar Craig Federighi to accelerate work on a more capable AI agent. That is a reported roadmap effort, not a feature confirmed for the current beta.
