Apple's WWDC 2026 Keynote Is Monday — Tim Cook's Final, With a Redesigned Siri Powered by Google Gemini

The Most Consequential WWDC in Years

Apple's Worldwide Developers Conference 2026 opens Monday, June 8, with a keynote at 10am PT — and this one carries more weight than most. For the first time in 14 years, Tim Cook will not be delivering it as Apple's CEO. He announced on April 20, 2026 that he will step down on September 1, handing the reins to John Ternus, the company's current Senior Vice President of Hardware Engineering. Cook becomes executive chairman. WWDC 2026 is his farewell keynote, and the platform he's chosen to close on is artificial intelligence.

Tim Cook's Final Keynote — and What Comes Next

John Ternus is not a surprise pick inside Apple. He has overseen the Apple Silicon transition, the M-series chip roadmap, and the structural engineering that turned the Mac into a powerhouse again. He is, by reputation, an engineer's engineer — methodical, technically rigorous, and far less interested in the stage than Cook ever was. His ascent signals that Apple's next chapter will be defined more by the silicon and system integration it controls than by the cultural narrative Cook built around privacy and values.

For long-time Apple watchers, the transition also raises real questions: Cook built the supply chain, the services business, and the wearables category from nothing. Ternus inherits a company under significant pressure on AI — pressure that this WWDC is explicitly designed to answer.

Siri Gets a Full Rebuild — Codenamed "Campo," Powered by Google Gemini

The headline feature of iOS 27 is a ground-up overhaul of Siri, internally codenamed "Campo." The rebuilt assistant abandons the rigid, command-response model Siri has used since 2011 in favor of a conversational, context-aware AI in the mold of ChatGPT or Claude. Campo will ship as a standalone app and integrates deeply into the Dynamic Island, giving it persistent, ambient presence on iPhone 14 Pro and later models.

What makes this notable — and somewhat surprising — is the engine underneath: Google Gemini. Apple, a company that has spent decades insisting on building its own core technologies, has entered an AI partnership with its biggest rival in mobile. The arrangement suggests Apple concluded it could not close the gap with OpenAI and Google fast enough on its own, at least not in the timeframe WWDC demands. For users, the practical upshot is a Siri that can hold a conversation, understand follow-up questions, reason across apps, and take multi-step actions without breaking the interaction into isolated commands.

The Gemini integration also raises questions Apple will need to address head-on about privacy — specifically, what data leaves the device, and under what conditions. Apple's differential privacy and on-device processing story has been central to its brand; how it reconciles that with a cloud-dependent language model will be one of the more interesting moments of the keynote.

iOS 27: The Full Feature Roundup

• AI photo editing and text generation: New tools baked into Photos and system-wide text fields let users retouch images, remove objects, rewrite copy, and generate content — competing directly with Google's Magic Eraser and Samsung's Galaxy AI suite.
• Apple Wallet bill-splitting: A long-requested feature arrives: splitting bills and expenses directly inside Wallet, with payment requests handled through Apple Pay.
• Custom Camera widgets: The Camera app gains configurable quick-access widgets, letting users surface specific shooting modes, lenses, or settings without digging through menus.
• Image Playground and Genmoji updates: Both AI image generation tools introduced in iOS 18 receive expanded style options, better prompt handling, and tighter integration with Messages and third-party apps.
• "Liquid Glass" UI refinements: The translucent, depth-layered interface language Apple debuted in iOS 26 continues to evolve, with more system surfaces adopting the aesthetic and improved performance on older hardware.

macOS 27 is expected to carry the same AI and UI updates to the desktop, with additional features tailored to the Mac's larger canvas and pro workflows.

Who Gets Cut: iPhone 11 May Be the Casualty

iOS 27 is expected to drop support for the iPhone 11 lineup — the iPhone 11, 11 Pro, and 11 Pro Max — all launched in 2019 on the A13 Bionic chip. The Campo Siri rebuild, with its heavier on-device inference requirements, is the likely driver. If confirmed at the keynote, it will be the largest single-year cut in recent memory, affecting tens of millions of devices still in use globally. iPhone 12 and later appear safe for now.

How to Watch, and What Happens After

The keynote streams live Monday, June 8 at 10am PT on Apple's website, the Apple TV app, and YouTube. The State of the Union for developers follows later the same day. If the pattern holds, Apple will release the first iOS 27 developer beta the same afternoon — so registered developers can start testing within hours of the announcements.

The public beta program is expected to open in mid-July, with the final public release landing in mid-September alongside new iPhone hardware. Between now and then, WWDC's session videos and labs give developers the first real look at the APIs underneath Campo — which will determine how quickly third-party apps can actually take advantage of the new Siri.
