Liquid Glass - Claude Code Skill

A Claude Code skill for building and migrating Apple platform apps with SwiftUI's Liquid Glass design system (iOS 26+, macOS 26+, iPadOS 26+).

What This Skill Does

When installed, Claude Code gains deep knowledge of Apple's Liquid Glass design system introduced at WWDC 2025. It can:

• Migrate existing apps to Liquid Glass with a structured 5-phase workflow
• Build new apps from scratch using glass-native patterns
• Apply all glass APIs correctly: .glassEffect(), .backgroundExtensionEffect(), .buttonStyle(.glass), GlassEffectContainer, morphing transitions, and more
• Handle platform differences across iOS, iPadOS, macOS, watchOS, tvOS, and visionOS
• Avoid common pitfalls with tested solutions for known issues

The skill auto-activates when you discuss SwiftUI glass design, or invoke it manually with /liquid-glass:liquid-glass.

Install

Step 1: Add the marketplace

/plugin marketplace add haider-nawaz/liquid-glass-skill

Step 2: Install the plugin

/plugin install liquid-glass@liquid-glass-skills

Step 3: Use it

Ask Claude Code to work with Liquid Glass — it will automatically apply the skill. Or invoke directly:

/liquid-glass:liquid-glass
