Tell me the main updates this year

This year at WWDC, Apple introduced a range of updates and new features across its platforms. Here are some of the main highlights:

Xcode and SwiftUI Enhancements: Xcode Previews now have a dynamic linking architecture, improving workflow efficiency. SwiftUI has received numerous updates, including custom hover effects for visionOS, new options for window behavior and styling in macOS, and a new text renderer API for enhanced visual effects (Platforms State of the Union).
SwiftUI Performance and Features: SwiftUI has seen significant performance improvements, with incremental changes like inserting new items up to 16 times faster. New features include powerful web APIs, rich text editing, 3D charts, and better control over drag and drop (Platforms State of the Union).
Design Updates: A major design update, referred to as Liquid Glass, has been introduced, marking a new era in Apple's software design. This update scales beautifully across Apple's apps and platforms, offering developers an opportunity to refresh and modernize their app designs (Platforms State of the Union).
Apple Intelligence and Foundation Models: New Apple Intelligence features enhance iPhone, Apple Watch, Apple Vision Pro, Mac, and iPad. The Foundation Models framework allows developers to use Apple's models for responses in plain text or structured Swift Data (Keynote).
VisionOS and Spatial Computing: VisionOS 26 introduces new volumetric APIs, advanced sharing capabilities, immersive media tools, and enterprise features, making it easier to build compelling volumetric experiences (Platforms State of the Union).
Device Management: Updates to Apple Business Manager and Apple School Manager, along with management updates to Apple platforms, aim to make it easier for IT administrators to deploy and manage Apple devices (What’s new in device management).
Wallet and Apple Pay: Enhancements include the ability to use Apple Pay on any non-Safari browser by scanning a code with an iPhone, and improvements to the ticketing experience (What’s new in Wallet and Apple Pay).
