WWDC26 Platforms State of the Union Recap
Five-minute WWDC26 recap covering Apple Intelligence updates, Liquid Glass design, SwiftUI improvements, Spatial Preview, Xcode 27, Device Hub, and agentic coding.
TL;DR
- Apple Intelligence is rebuilt with new Apple Foundation Models, expanded Foundation Models framework capabilities, Core AI for on-device models, App Intents, and View Annotations.
- Platform updates include Liquid Glass design refinements, sharper app icon rendering, resizable iOS apps on larger displays, and better Simulator and preview resizing workflows.
- SwiftUI gains broader drag-to-reorder and swipe actions, faster nested layouts, automatic async image caching, improved toolbar control, and Spatial Preview for Apple Vision Pro workflows.
- Xcode 27 focuses on daily productivity and agentic coding: faster and smaller Apple Silicon-only Xcode, iCloud settings sync, Device Hub, faster Xcode Cloud, and extensible coding agents.
Intelligence across apps and the system
Apple Intelligence is described as rebuilt from the ground up, with Apple working with Google and technologies behind the Gemini family of models to create the latest Apple Foundation Models for integrated Apple Intelligence experiences.
The Foundation Models framework expands beyond prior capabilities with image input and support for cloud models. For complex tasks that need more advanced frontier models, apps can integrate with a cloud model provider selected by the developer.
Dynamic profiles are positioned as a way to build AI agents and skills with less code by changing tools and instructions at runtime.
- Core AI is a new framework for running on-device models in apps, built into the OS and optimized for Apple Silicon.
- App Intents connect app actions and user content to Apple Intelligence and Siri natural-language interactions.
- The new View Annotations API lets users act on visible on-screen content by asking.
Design and platform refinements
The recap highlights a new design language with Liquid Glass, emphasizing consistency, personalization, and readability across the platforms.
On macOS, windows share a tighter corner radius. App icons receive sharper rendering automatically, and Icon Composer can add new refraction effects.
- iOS apps are now resizable, helping users make better use of larger displays when running iOS apps on iPad or on Mac using iPhone Mirroring.
- Resizable iOS Simulator and previews make size-class and layout testing easier across multiple dimensions.
- Icon Composer and app icon rendering updates are part of the design workflow changes.
SwiftUI and spatial development updates
SwiftUI receives performance and interaction improvements aimed at making common app layouts and controls more flexible.
- Drag to reorder and swipe actions now work in any container.
- Nested layouts resize up to twice as fast.
- Async image caching happens automatically.
- Toolbars provide finer control over which items remain visible as available space shrinks.
- For Apple Vision Pro, the Spatial Preview framework streams 3D models from a Mac into the surrounding space.
Xcode 27 daily development improvements
Xcode 27 is presented around two themes: the daily development experience and agentic coding. It is Apple Silicon-only and 30% smaller, with faster project loading.
Developer environment improvements include iCloud settings sync, a fully customizable toolbar, and app-wide color themes such as Emerald, Neon Noir, and Coral Reef.
- Xcode Cloud setup is easier, builds can be up to twice as fast, and support is added for Apple Vision Pro and apps using Metal on Apple Silicon.
- Device Hub replaces Simulator and brings virtual and physical devices into one place.
- Device Hub supports workflows such as pinch to zoom, live resizing, and controlling real hardware from the Mac.
Agentic coding in Xcode
Xcode expands AI coding assistance by integrating agents from leading model providers, including Anthropic, OpenAI, and Google. Agent conversations behave like files that can be opened, split, stacked, and managed in the Navigator.
Agents can plan before writing code so developers can review the approach first. They can also run tests, use playgrounds, customize previews, and drive a running app by tapping, scrolling, swiping, and typing for end-to-end validation.
- Xcode 27 includes built-in specialists based on Apple engineering and design expertise for SwiftUI, accessibility, sizing, testing, and performance.
- Plugins can add skills, MCP tools, and agents through the agent-client protocol.
- Figma and GitHub provide plugins with one-click setup.
