Design Tweaks and Core AI Framework

On this week's episode of The MacRumors Show, we discuss Apple's announcement of its 37th annual Worldwide Developers Conference (WWWDC), where the company is expected to unveil a major Siri overhaul alongside iOS 27, macOS 27, and other next-generation operating systems.

Like last year, WWDC 2026 will be a primarily online event open to all developers at no cost, with an in-person component at Apple Park in Cupertino reserved for developers and students selected through a random lottery. Apple will notify accepted in-person attendees on April 2. The keynote and all sessions will be available on the Apple Developer app, Apple's website, and YouTube, with over 100 video sessions and interactive labs with Apple engineers and designers planned across the week.

Apple first unveiled Apple Intelligence at WWDC 2024, promising a smarter Siri with personal context, on-screen awareness, and deeper app integration, features that were delayed in March 2025, delayed again at WWDC 2025, and then missed a further internal target of iOS 26.4. Apple confirmed in its announcement that the conference will "spotlight incredible updates for Apple platforms, including AI advancements and exciting new software and developer tools," which points clearly to what is shaping up to be the most consequential ‌Siri‌ update ever.

The revamped ‌Siri‌ is said to be a sweeping redesign that turns Apple's long-struggling assistant into a full AI chatbot, with Bloomberg's Mark Gurman reporting that Apple is testing a standalone ‌Siri‌ app displaying prior conversations in a list or grid, with pinned and searchable chats and iMessage-style chat bubbles. ‌Siri‌ is also said to be gaining Dynamic Island integration, with a glowing icon and "searching" label while processing requests, an "Ask ‌Siri‌" button in third-party app menus, and a "Write with ‌Siri‌" keyboard option, while Spotlight is expected to be replaced by ‌Siri‌ as the primary search interface on iPhone.

The technology underpinning virtually all of this comes from Apple's multi-year partnership with Google, under which next-generation Apple Foundation Models are based on Gemini, with processing continuing to run on-device and in Private Cloud Compute. Separately, Apple plans to open Siri to third-party AI chatbots in ‌iOS 27‌ via an "Extensions" system in Settings, ending OpenAI's exclusive arrangement and allowing users to direct queries to Claude, Gemini, Grok, and others.

Beyond ‌Siri‌, iOS 27 is expected to be a relatively lean update, described as a "Snow Leopard" year, focused on performance improvements, bug fixes, and code cleanup rather than major new feature additions. Notable exceptions include optimizations for Apple's first foldable iPhone, which is expected to launch in the fall, and new satellite connectivity features.

macOS 27 will apparently share the same ‌Siri‌ upgrades and "Snow Leopard" stability focus. It will drop support for Intel-based Macs entirely. Apple will also unveil iPadOS 27, watchOS 27, tvOS 27, and visionOS 27 at the keynote.
