Apple’s WWDC 2026 keynote was its most AI-heavy ever, moving Apple Intelligence from a foundation into a shipping platform. For iOS and macOS developers, the announcements translate directly to new APIs and a clear architectural direction: on-device inference first, Private Cloud Compute second, and third-party models only when the user opts in.
Siri Gets Personal Context
Context-aware Siri fuses on-device foundation models (~3B parameters, ~30 tokens/second) with Private Cloud Compute for heavier tasks. Developers integrate via the App Intents framework — no phrase definitions needed. The new View Annotations API lets you map on-screen UI elements to your app’s entities, so Siri can reference what the user sees conversationally.
Describe a Shortcut
The Shortcuts app now assembles multi-step automations from natural language. Users say “When I leave work, text my wife and start my driving playlist” and Shortcuts builds the workflow. Your app becomes a composable building block: well-structured App Intents with clear input/output schemas are all it takes to be discovered.
Camera Visual Intelligence
The Camera app runs on-device foundation model inference for real-time object recognition, text translation, and scene understanding. If your app uses the camera, you can tap the same pipeline via the Foundation Models framework, which supports multimodal prompts and any model provider conforming to the Language Model protocol.
Spotlight AI Goes Semantic
macOS and iOS Spotlight now uses Apple’s server-side foundation model for semantic search. Queries like “Show me the marketing deck from last quarter” work out of the box. Contribute your app’s content to the semantic index through App Intents entity schemas, and users find it without knowing exact filenames.
Google Gemini Joins the Party
Following last year’s ChatGPT integration, Apple now offers Google Gemini as a third-party model provider in Siri. Users choose ChatGPT, Gemini, or Apple’s own server models. Siri always asks permission before sending data, and the opt-in flow is identical across providers — no provider-specific consent logic needed from developers.
Private Cloud Compute
Underpinning it all is PCC: custom Apple silicon servers with Secure Enclave, stateless request handling, end-to-end encryption, and no admin shells. Every production build’s software images are published for independent verification. For developers, PCC is invisible — Apple handles all of it transparently.
The bottom line: Adopt App Intents now. Add View Annotations. Structure your Shortcuts intents. Apple is betting that on-device AI with privacy-first cloud fallback is the mobile future — and your app needs to be on the other end of that Siri request.
