Liquid Glass Design Overview

​

What is Liquid Glass?

• Blurs content behind it
• Reflects color and light from surroundings
• Reacts to touch and pointer interactions
• Morphs between shapes during transitions

​

Platform Availability

​

Core Concepts

​

Glass Variants

• Regular: Standard glass effect
• Prominent: Enhanced visibility with tint
• Interactive: Responds to user input

​

Container Optimization

• AppKit: NSGlassEffectContainerView
• SwiftUI: GlassEffectContainer

​

Key Properties

• cornerRadius / shape: Visual appearance
• tintColor / .tint(): Color overlay
• spacing: Merge distance threshold

​

Quick Start

​

SwiftUI

Text("Hello").glassEffect()
Button("Click").buttonStyle(.glass)

​

AppKit

let glass = NSGlassEffectView()
glass.cornerRadius = 12.0
glass.contentView = myView

​

Performance Guidelines

1. Use containers for multiple glass views
2. Limit total glass effects on screen
3. Consider GPU impact on older devices
4. Batch similar effects together
