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 Use

• 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
• Migrating existing blur/material effects to the new Liquid Glass API

Core Pattern — SwiftUI

Basic Glass Effect

The simplest way to add Liquid Glass to any view:

Text("Hello, World!")
    .font(.title)
    .padding()
    .glassEffect()  // Default: regular variant, capsule shape

Customizing Shape and Tint

Text("Hello, World!")
    .font(.title)
    .padding()
    .glassEffect(.regular.tint(.orange).interactive(), in: .rect(cornerRadius: 16.0))

Key customization options:

• .regular — standard glass effect
• .tint(Color) — add color tint for prominence
• .interactive() — react to touch and pointer interactions
• Shape: .capsule (default), .rect(cornerRadius:), .circle

Glass Button Styles

Button("Click Me") { /* action */ }
    .buttonStyle(.glass)

Button("Important") { /* action */ }
    .buttonStyle(.glassProminent)

GlassEffectContainer for Multiple Elements

Always wrap multiple glass views in a container for performance and morphing:

GlassEffectContainer(spacing: 40.0) {
    HStack(spacing: 40.0) {
        Image(systemName: "scribble.variable")
            .frame(width: 80.0, height: 80.0)
            .font(.system(size: 36))
            .glassEffect()

        Image(systemName: "eraser.fill")
            .frame(width: 80.0, height: 80.0)
            .font(.system(size: 36))
            .glassEffect()
    }
}

The spacing parameter controls merge distance — closer elements blend their glass shapes together.
