WWDC 2026: iOS 27's New Siri Makes App Intents Non-Optional

The Keynote Opens on a Rebuilt Siri

Apple’s WWDC 2026 keynote kicked off this morning with the company’s most significant Siri overhaul since the assistant launched in 2011. iOS 27, announced alongside macOS 27 and a suite of Apple Intelligence updates, puts a rebuilt Siri at the center of the operating system rather than at its edge. The new Siri runs as a standalone app, understands text, voice, and attachments in a single conversation thread, searches the web natively, and — most consequentially for developers — takes actions inside apps and chains those actions across multiple apps.

That last capability is the one that changes how you build.

What “Cross-App Actions” Actually Means

The phrase Apple is using — “actions inside and between apps” — is shorthand for the App Intents framework doing real work at scale. App Intents, introduced in iOS 16 and quietly expanded every year since, lets developers expose discrete pieces of their app’s functionality to the system. Previously that meant Shortcuts automation and a handful of voice triggers. With Siri 2.0, it means a user can ask Siri to book a session in your app and add it to their calendar, and the system figures out the handoffs between your app and Calendar without you writing glue code.

Every app that has not invested in App Intents is now invisible to Siri’s most powerful new surface.

The practical implication: your App Intents need to model the actual tasks users want to accomplish, not just expose internal navigation. “Open the booking screen” is a navigation intent. “Book a session for tomorrow morning” is a task intent. iOS 27 Siri works with the second kind. If your current intents are thin wrappers around deep links, this beta cycle is the time to rethink them.

The Gemini Backend: What It Means for Privacy

Apple confirmed that the rebuilt Siri uses Gemini for its large language model reasoning — a significant departure from the company’s previous strategy of building proprietary on-device models. This mirrors the pattern Apple established in iOS 18, when it added ChatGPT as an opt-in fallback, except the external model is now doing substantially more of the heavy lifting.

The privacy story gets more complex as a result. Apple has historically earned its privacy reputation through technical architecture: on-device processing with enforceable guarantees. With Gemini handling cloud-side reasoning, those guarantees shift from technical to contractual — dependent on Apple’s agreement with Google rather than hardware isolation. For teams building iOS 27 Siri integrations in regulated sectors — healthcare, finance, legal — that distinction belongs in your privacy documentation and your next conversation with your legal team.

Apple is expected to publish detailed data-handling documentation in its WWDC session on AI privacy. Read it before you ship any intent that processes personal or health data.

iOS 27 Siri 2.0 Ships in Beta, With a Waitlist

Pre-announcement reporting from TechRadar and 9to5Mac indicates Siri 2.0 will ship under a beta label with a waitlist — the same phased rollout model Apple used when it launched original Apple Intelligence features in late 2024. That rollout was rough: features announced in June arrived months after the iOS release, and some didn’t ship until the following spring.

The waitlist signals Apple cannot scale AI inference fast enough to give every user access on day one. For developers this creates a familiar testing problem: you can build against the Siri 2.0 APIs in the developer beta, but you cannot assume your users have access when your update ships. Every new App Intent you write needs to degrade gracefully for users still on standard Siri. Plan for it now rather than scrambling in November.

macOS 27 Drops Intel: Take the Gift

macOS 27 ends support for Intel Macs. If you’re still building universal binaries out of habit rather than necessity, this is Apple telling you to stop. Apple Silicon has been the default since 2020; targeting it exclusively means smaller binaries, access to the Neural Engine for on-device inference, and Metal 4 without the Intel fallback paths.

The work is usually straightforward: audit third-party dependencies for any x86-only paths, remove the Intel architecture from your Xcode build targets, and update CI pipelines still running on Intel agents. Most teams are 90% of the way there. This is the nudge to finish.

Foldable iPhone: Start the Layout Work Now

iOS 27 includes foldable iPhone support, confirming that Apple’s first foldable device is close enough to ship for Apple to want developers testing against it. The hardware is not announced yet, but the OS scaffolding is there. If your apps have rigid portrait-only layouts or hardcoded assumptions about screen dimensions, fix them during this beta cycle rather than in the week before a new device ships. SwiftUI’s adaptive layout system and UITraitCollection handle the fold geometry when you’re not fighting them.

What We’re Watching

The WWDC session list Apple publishes today will tell us whether App Intents gets the API surface expansion that makes cross-app actions truly composable — or whether the keynote story is UI-layer polish on top of the existing framework. We are expecting the former, because the cross-app capability described today requires richer entity modeling and intent chaining than the current framework exposes.

At Dracode, the apps we ship for founders and scale-ups are iOS-first by default. The shift toward Siri as a first-class app entry point changes the discovery calculus for every product we build. If you’re planning an iOS app and haven’t thought about its Siri surface area yet, that conversation belongs in the design phase — not after launch.
