Liquid Glass Design for iOS

Implementation patterns for Apple's Liquid Glass design system in iOS 26+ and iPadOS 26+, covering SwiftUI glassEffect APIs and UIKit NSGlassEffectView integration.

Overview

Liquid Glass is Apple's next-generation frosted glass design pattern for iOS 26 and iPadOS 26+. It provides visual hierarchy, depth, and interactive feedback through translucent glass layers with tint and blur effects. Use glassEffect to create adaptive, accessible glass overlays that enhance UI without sacrificing readability.

Rules

See rules index for detailed patterns covering:

• Glass effect usage and proper layer placement
• Accessibility with glass effects (contrast, readability, reduced transparency)
• Fallback patterns for pre-iOS 26 versions
• Performance optimization for glass rendering
• Color and tint management
