Apple WWDC 2026 Preview: iOS 27, Siri AI Overhaul, and More

Apple's WWDC 2026 keynote lands June 8 at 10 a.m. PT, and this one is different. The Apple WWDC 2026 preview points to a long-overdue Siri overhaul, a full suite of iOS 27 updates, and the first public look at macOS 27. After years of incremental AI progress, Apple is going bigger — and leaning on Google to do it.

Key Takeaways: What's Coming at WWDC 2026

• Siri gets a full rebuild — dedicated app, chat history, Gemini AI backbone
• iOS 27 is the "Snow Leopard" release — stability and performance-first, not feature bloat
• macOS 27 drops Intel support — M1 chip minimum requirement
• Apple Intelligence expands — third-party AI services can now be set as default
• WWDC keynote streams June 8, 10 a.m. PT on Apple's YouTube channel

The Siri Overhaul Apple Has Been Stalling On

Siri is finally getting its complete AI reboot — the one Apple announced two years ago at WWDC 2024 and then promptly delayed. iOS 27 brings a standalone Siri app with saved chat history, persistent conversation context, and a chatbot-style interface that rivals ChatGPT and Gemini.

When you trigger Siri, the Dynamic Island will show a "Search or Ask" prompt. Swipe down and you get a full conversational interface. Swipe again for the expanded chat view. Apple has also redesigned Siri's visual identity with a dark color scheme, matching the WWDC 2026 artwork.

The biggest revelation is the engine underneath: Apple has licensed Google's Gemini models to power Siri after its own AI models struggled to keep up. According to MacRumors, this gives Siri multi-step reasoning, contextual memory, and on-screen awareness — features that should finally make it competitive with Google Assistant and ChatGPT.

iOS 27: What's Actually Changing

iOS 27 is being framed as a "Snow Leopard" update. For those who weren't around in 2009, that's Apple-speak for: we're cleaning up the codebase, fixing bugs, and making things faster instead of piling on features.

That said, there's still plenty coming:

Camera and Photos: A new AI Camera mode sits alongside Video and Portrait in the app. The Photos editor adds three new AI tools — Extend, Enhance, and Reframe — for fixing poorly framed shots. The scan-to-generate-wallet-pass feature lets you photograph a concert ticket or gym membership card and create a digital pass automatically.

Connectivity: iOS 27 adds 5G satellite internet support, expanding off-grid connectivity to more devices and regions.

Apple Intelligence flexibility: Users can now set third-party AI services — including ChatGPT — as the default for Writing Tools and Image Playground, rather than being locked into Apple's own model.

Device compatibility: iOS 27 will run on iPhone 12 and newer. Apple Intelligence features, however, require at least an iPhone 15 Pro or any iPhone 16 model.

macOS 27: The End of Intel Macs

macOS 27 marks a hard cutoff: Intel Macs are out. You'll need an Apple Silicon Mac — M1 or newer — to run it. That's a significant change that will push a lot of older hardware into legacy territory when the update drops in September 2026.

The interface is also getting refinements. The Liquid Glass design from macOS 26 had readability complaints, and Apple is introducing a system-wide transparency slider so users can dial back the visual effects. According to Macworld, the macOS 27 update will also include the full AI Siri integration, not a watered-down desktop version.

Apple vs. Google: The AI Arms Race Heats Up

Apple's use of Gemini to power Siri is a striking admission. The company has positioned Apple Intelligence as its own, privacy-first AI solution — and now it's quietly licensing from the same company whose I/O conference it competes with every spring. Our Google I/O 2026 highlights piece covers what Google announced on the other side of this AI battle.

Feature	iOS 27 / WWDC 2026	Google I/O 2026
AI assistant	Gemini-powered Siri	Gemini 2.0
On-device privacy	Yes (Apple Silicon)	Partial
Third-party AI support	Yes, as default	Yes
Release window	September 2026	Rolling now
Hardware cutoff	iPhone 12+ (AI: 15 Pro+)	Pixel 8+ for advanced AI
