Liquid Glass Design System (iOS 26)

Patterns for implementing Apple's Liquid Glass — a dynamic material that blurs content behind it, reflects color and light from surrounding content, and reacts to touch and pointer interactions. Covers SwiftUI, UIKit, and WidgetKit integration.

When to Activate

• Building or updating apps for iOS 26+ with the new design language
• Implementing glass-style buttons, cards, toolbars, or containers
• Creating morphing transitions between glass elements
• Applying Liquid Glass effects to widgets

• .regular — standard glass effect

• .interactive() — react to touch and pointer intera…
