Apple's Worldwide Developers Conference kicks off on June 8, 2026 β€” and for the first time in years, the biggest story is not hardware. It is Siri. Apple's long-mocked voice assistant is being rebuilt from the ground up as a full-blown AI chatbot, powered by Google's Gemini models, and the result may be the most consequential software update Apple has shipped since the original iPhone.

WWDC26 runs June 8–12, 2026 at Apple Park's Steve Jobs Theater (with online streaming on apple.com, the Apple TV app, and YouTube). The keynote is Monday, June 8 at 10:00 AM Pacific. Here is everything expected β€” and why this is Apple's most important developer conference in a decade.

The Biggest Change: Siri Is Dead. Long Live Siri.

The Siri being unveiled at WWDC 2026 is not an incremental improvement on the voice assistant that has struggled for years to answer basic questions correctly. According to reporting from MacRumors, Apple is shipping a complete ground-up rebuild that turns Siri into a ChatGPT-class conversational AI.

The interface has been redesigned entirely. Instead of the familiar waveform at the bottom of the screen, the new Siri lives in the Dynamic Island β€” a pill-shaped animation that expands into a transparent card with results. Swiping down from the center of the iPhone Home Screen activates it. There is now a standalone Siri app for back-and-forth conversation, styled like an iMessage chat interface. The new UI uses a dark color scheme exclusively.

What the new Siri can actually do:

  • Personal context: Access to emails, messages, files, and photos. Ask "show me files Eric sent me last week" or "what is my passport number" and Siri retrieves it from your data, on-device.
  • Onscreen awareness: Siri sees what is currently on your screen. If someone texts you an address, Siri can add it to a contact without you copying and pasting.
  • Cross-app actions: Move files, edit photos, send your ETA via Messages β€” all in a single instruction across multiple apps.
  • AI-powered web search: Summarized web results delivered conversationally, not a list of blue links.
  • Memory: Siri remembers context across requests and retains user details β€” with configurable data retention (30 days, 1 year, or permanent).
  • Third-party AI extensions: Claude and Gemini can be plugged into Siri as extensions, expanding the existing ChatGPT support. Users can set third-party chatbots as default for Writing Tools and set third-party AI voices.

The Google Deal: Why Apple is Using Gemini

The most significant and least publicized development leading into WWDC 2026 is Apple's multi-year partnership with Google to use Gemini AI models as the foundation for Apple's own intelligence features. According to MacRumors, Gemini powers the next generation of Apple Foundation Models and future Siri capabilities.

This deal is remarkable for several reasons. Apple has historically been aggressively protective of its supply chain independence β€” the M-series chips exist precisely because Apple did not want to depend on Intel. Partnering with Google for the core AI infrastructure of its most visible consumer product represents a meaningful strategic shift. It also appears to be coming at some cost to the existing ChatGPT partnership: Bloomberg and The Verge reported in May that OpenAI is considering legal action against Apple over a potential breach of their existing AI partnership terms.

The practical result for users: Apple Intelligence on the new Siri will be backed by Google's Gemini 3.5-era models β€” some of the most capable AI systems available β€” while maintaining Apple's on-device processing for privacy-sensitive data.

iOS 27 and the New Naming Convention

Apple shifted to a numerical naming convention in 2025 β€” iOS 26 launched with iOS 26, and the 2026 release is iOS 27 (not "iOS 20" as some early rumors suggested). The same applies across all platforms: macOS 27, watchOS 27, iPadOS 27, visionOS 27, tvOS 27.

Key iOS 27 features expected beyond the Siri rebuild:

  • Camera app: New Siri section for Visual Intelligence β€” point your camera at something and ask questions about it
  • Wallet app: Scan physical passes to create digital versions; new bill-splitting feature
  • Photos: AI editing features with natural-language instructions
  • AI Shortcuts: Build automations using plain English descriptions instead of programming logic
  • AI wallpaper generator: Generate custom wallpapers on-device, similar to Samsung and Google's implementations
  • Grammar checking: Grammarly-like grammar suggestions built into iOS text fields system-wide
  • Google Cast support: Native support for Google Cast and other AirPlay alternatives, required by EU Digital Markets Act
  • iPhone Fold optimizations: Side-by-side apps and new sidebars for the foldable iPhone expected in September 2026

Device compatibility for Apple Intelligence features remains iPhone 15 Pro or later β€” the A17 Pro chip is the minimum hardware requirement for on-device AI processing.

Leadership Change: Tim Cook Out, John Ternus In

WWDC 2026 will be the first major Apple developer conference under new CEO John Ternus, who took over from Tim Cook following Cook's departure (reported by Bloomberg in May 2026). Ternus, Apple's former SVP of Hardware Engineering, represents a shift toward a hardware-first executive perspective at the top of Apple β€” unusual given that this WWDC is so heavily software-focused.

Johny Srouji, who took over as Chief Hardware Officer, has been reorganizing Apple's chip and product teams to better align semiconductor development with product roadmaps β€” the motivation behind the ongoing push to bring even low-end chip manufacturing to Intel (on a small scale, with TSMC retaining roughly 90% of Apple silicon production).

macOS 27: Liquid Glass Refined, Not Removed

The macOS version shipping alongside iOS 27 β€” name not yet confirmed as of June 3 (MacRumors floated possibilities from "Emerald" to "Big Bear") β€” will carry the same AI and Siri improvements as iOS 27, plus refinements to the Liquid Glass design language introduced in macOS Tahoe 26.

Mark Gurman's reporting indicates that Liquid Glass β€” the transparent, blur-heavy UI aesthetic that debuted in 2025 β€” is not being removed. It is being refined. Specific improvements target readability: text-heavy areas with transparency and shadow issues identified by users and developers in the 26 release cycle. The current production version, macOS Tahoe 26.5.1 (released June 1, 2026), fixed an enterprise shutdown issue affecting M5 Macs.

The macOS 27 release is being described by some as a potential "Snow Leopard" update β€” prioritizing performance optimization, stability, and battery life improvements over headline new features. Given the scope of changes in the Liquid Glass redesign cycle, this is consistent with Apple's historical pattern of a big-change year followed by a refinement year.

watchOS 27: Blood Pressure and New Watch Faces

Three confirmed watchOS 27 features via 9to5Mac:

  1. High blood pressure notifications: A new health sensor feature currently under FDA review. If approved, Apple Watch would join blood oxygen and ECG as a cleared medical monitoring feature.
  2. Heart-rate tracking improvements: Better accuracy and more granular data available through the existing heart-rate sensor on current hardware.
  3. New Modular Ultra watch face for standard Apple Watch: The Modular Ultra face β€” previously exclusive to Apple Watch Ultra β€” comes to the standard Apple Watch Series. Large clock fills the top two-thirds of the display, with three complications below.

The overall watchOS 27 theme is "stability, performance, and smaller refinements" per Bloomberg β€” consistent with the macOS approach of consolidating gains from the prior year's big release.

MacBook Neo: The Mac Hardware Story You May Have Missed

While WWDC is not expected to include Mac hardware announcements, the biggest Mac story of 2026 has already happened: the MacBook Neo, launched in mid-March 2026 at $599.

The MacBook Neo uses the A18 Pro chip (not the M-series) to hit the $599 price point, making it Apple's most affordable Mac laptop ever. It shipped 1.1 million units in its debut quarter β€” outselling every other Mac including the M5 MacBook Air (900K units) and M5 MacBook Pro (550K units). Counterpoint Research estimates it could grow Apple's share of the $400–$699 notebook market from approximately 2% to 15%. Dell has already responded with a new XPS 13 starting at $699.

What to Watch on June 8

The keynote starts at 10:00 AM Pacific on June 8. Developer betas ship the same day. Public betas follow in July; final releases in September 2026.

The moments that matter most:

  • The Siri demo: Apple will show the rebuilt Siri in action for the first time. The quality of this demo β€” whether the new Siri actually works reliably on stage β€” will define the narrative for the next six months.
  • The Gemini partnership acknowledgment: How Apple positions and discloses its Google AI partnership will be telling. A quiet "powered by" mention versus a featured partnership stage moment signals the depth of the deal.
  • Third-party AI integrations: The announcement that Claude and other AI providers can plug into Siri is significant for developers. The terms of those integrations (revenue sharing, data handling) matter as much as the feature itself.
  • Any hardware surprise: New Apple TV and HomePod mini were reported as "nearly ready" by MacRumors in late May. A WWDC surprise is possible.

WWDC 2026 is Apple's answer to a question the tech industry has been asking for two years: what does the company that makes the world's most-used consumer device do in the age of AI? Based on everything leaked so far, the answer is: rebuild Siri completely, partner with Google for the AI foundation, and ship the most capable iPhone software Apple has ever made. Whether that is enough to catch up with ChatGPT and Gemini in consumer mindshare remains to be seen on June 8.

Apple Intelligence 2.0: What Changed From the 2025 Version

Apple Intelligence launched with iOS 26 in 2025 to mixed reviews. The core critique was accurate: Siri's AI features were slow to roll out, required iPhone 15 Pro minimum hardware, were limited to English at launch, and failed to meaningfully close the capability gap with ChatGPT in everyday use. The rebuilt Siri coming in iOS 27 is Apple's response to that criticism.

The architectural change is fundamental. The 2025 Apple Intelligence relied heavily on a combination of small on-device models (for privacy-sensitive tasks) and a connection to ChatGPT (for more complex queries via a server-side integration). The 2026 version replaces ChatGPT as the primary cloud AI backbone with Google's Gemini models β€” a dramatically more capable foundation β€” while maintaining on-device processing for sensitive personal data.

The practical upgrade path:

  • 2025 Apple Intelligence: Limited Siri integration, writing tools (summarize, rewrite), photo cleanup, notification summaries, basic ChatGPT pass-through for complex queries
  • 2026 Apple Intelligence: Full chatbot-class Siri rebuild, cross-app actions, personal context (email, messages, files), AI Shortcuts, grammar checking, AI wallpaper generation, Claude and Gemini as alternative AI backends

The jump from 2025 to 2026 Apple Intelligence is the largest single-year capability improvement in Siri's fifteen-year history. Whether Apple can execute the keynote demo reliably across hundreds of millions of devices β€” rather than in a controlled conference environment β€” is the $1 trillion question.

Developer Implications: What WWDC 2026 Means if You Build for Apple

The WWDC26 developer portal promises 100+ session videos, live Group Labs with Apple engineers, and same-day developer betas on June 8. For the 35+ million registered Apple developers, the key new capabilities to build for are:

  • Siri Extensions API: Third-party apps can now expose functionality directly to Siri, enabling the kind of cross-app actions that were previously only available to Apple's own apps. A task management app, for example, could let Siri create tasks from email context without the user ever leaving Siri.
  • AI Shortcuts: Natural language automation creation lowers the barrier for building powerful Shortcuts automations β€” potentially expanding the Shortcuts user base from technical power users to mainstream iPhone users.
  • Visual Intelligence API: Camera-based AI query capability opens a new category of apps β€” real-world object identification, text extraction, spatial computing interactions.
  • Apple Intelligence Writing Tools: Third-party apps can integrate system-level grammar checking and rewriting capabilities, raising the baseline writing quality across the ecosystem.

The Extensions section of the App Store β€” a dedicated area for AI-integrated apps β€” represents Apple acknowledging that AI app discovery requires a new UI category, not just keyword search. For developers building AI-enhanced applications, this is the distribution channel to understand before September 2026.

The OpenAI Split: What It Means for Users

The most diplomatically awkward aspect of WWDC 2026 is the implicit message about OpenAI. Apple's ChatGPT integration β€” the signature partnership announced at WWDC 2024 and shipped with iOS 26 β€” is being repositioned from primary AI backbone to one option among several. Gemini is now the foundation; Claude and Gemini can both be set as default AI backends; ChatGPT remains available but is no longer the headline feature.

Bloomberg and The Verge reported in May 2026 that OpenAI is considering legal action against Apple over the company's handling of the original AI partnership agreement. The specifics are not public, but the timeline aligns: Apple appears to have shifted its AI strategy toward Google before the original ChatGPT partnership's terms anticipated such a move.

For iPhone users: in practice, the new Siri will be significantly more capable regardless of which AI backend powers it. The choice of Claude, Gemini, or ChatGPT as an alternative will matter for specific use cases (coding questions where Claude excels, creative writing, domain-specific knowledge). Apple's UI will abstract most of this complexity β€” most users will use Siri without ever selecting a specific underlying model.
