Apple has published a five-minute recap video summarizing the key announcements from its WWDC26 Platforms State of the Union, covering rebuilt intelligence frameworks, platform design changes, and major developer tools updates.
Apple said its Foundation Models have been rebuilt from the ground up in collaboration with Google, leveraging technology from the Gemini family of models. The Foundation Models framework now supports image input and cloud model integration, allowing developers to connect to any cloud model provider for more complex tasks.
New dynamic profiles are also included to simplify building AI agents and skills by swapping tools in and out and updating instructions on the fly. Core AI, an entirely new framework for running on-device models, is built into the OS and designed to take full advantage of Apple Silicon.
App Intents have been updated to connect apps to Apple Intelligence, making content discoverable and actions available through Siri via natural language, with a new View Annotations API allowing users to act on what's on screen just by asking.
The refined Liquid Glass design system features prominently in the recap. Apple said the design is more consistent and personalizable, with better readability. On macOS, every window now shares a tighter corner radius. App icons receive sharper rendering automatically, with new refraction effects available through Icon Composer.
iOS apps are now resizable, allowing users to take advantage of larger displays when running them on iPads or Macs via iPhone mirroring, with a new resizable iOS Simulator to make testing across sizes easier.
SwiftUI received a range of updates, including drag-to-reorder and swipe actions in any container, nested layouts that resize up to twice as fast, and automatic async image caching. Toolbars now offer finer control over visibility as space shrinks, and a new Spatial Preview Framework for the Apple Vision Pro lets developers stream 3D models from a Mac into physical space.
In Xcode 27, projects load faster and the app is 30% smaller as it moves to Apple Silicon-only. Settings now sync via iCloud, the toolbar is fully customizable, and themes including Emerald, Neon Noir, and Coral Reef bring color throughout the app.
Xcode Cloud is easier to set up with builds up to twice as fast. A new Device Hub replaces Simulator, bringing virtual and physical devices together in one place with live resizing and full hardware control from the Mac.
Apple said it is working with Anthropic, OpenAI, and Google to bring their agents into Xcode. Agent conversations now behave like files and can be opened, split, and stacked in the Navigator. Agents can run tests, use Playgrounds, customize previews across light and dark mode and other configurations, and drive a running app end-to-end. Developers can extend Xcode further through plugins that bring skills, MCP tools, and agents via the agent-client protocol, with Figma and GitHub shipping their own plugins at launch.
