Liquid Glass Design System for Apple Platforms

Build and migrate SwiftUI apps using Apple's Liquid Glass design language introduced at WWDC 2025. This skill covers iOS 26, iPadOS 26, macOS 26 (Tahoe), watchOS 26, tvOS 26, and visionOS 26.

Important: Use Latest Documentation

Always fetch the latest Apple developer documentation when implementing Liquid Glass features. The APIs may evolve between OS betas. Key documentation URLs to reference:

Core Concept

Liquid Glass is a translucent, dynamic material exclusively for the navigation layer (toolbars, tab bars, buttons, controls) that floats above app content. It bends and refracts light in real-time, responds to device motion with specular highlights, and adapts continuously to background content.

Never apply glass to content itself (lists, tables, media, text blocks). Glass is for controls and navigation only.
