Apple kept three major features out of its WWDC iOS 27 announcement despite having them ready in internal builds, according to Bloomberg's Mark Gurman. All three are currently running on employee devices and expected to launch publicly later this year.

Siri Extensions leads the list, enabling third-party AI chatbots like those from OpenAI, Anthropic, and Google to integrate directly with Siri and Apple Intelligence tools. The framework already exists in iOS 27 developer betas with dedicated settings panels and an App Store section awaiting activation.

A customizable Camera app that lets users rearrange controls as widgets will likely debut with the iPhone 18 Pro this fall. Meanwhile, a simplified Modular watch face for Apple Watch missed the keynote but should arrive alongside new watch models. Apple reportedly discussed the Extensions framework with multiple AI companies, though Gurman cites regulatory concerns and potential litigation as reasons for the WWDC delay.

The hidden features reveal Apple's cautious approach to AI partnerships amid ongoing regulatory battles. With the technical groundwork already built, these additions will likely strengthen iOS 27's competitiveness against Android's more open AI ecosystem when they eventually launch.
