Swiftui Liquid Glass

Implement, review, or improve SwiftUI features using the iOS 26+ Liquid Glass API. Use when asked to adopt Liquid Glass in new SwiftUI UI, refactor an existing feature to Liquid Glass, or review Liquid Glass usage for correctness, performance, and design alignment.

Security Scan

This is an instruction-only SwiftUI guidance skill about iOS 26+ Liquid Glass that is internally consistent: it needs no credentials, installs, or system access and its instructions stay on-topic.

Purpose & Capability

The name/description (SwiftUI Liquid Glass) match the content: all required functionality is SwiftUI UI guidance and code snippets. There are no unrelated required binaries, env vars, or config paths.

Instruction Scope

SKILL.md and the reference file only contain SwiftUI code examples, API usage patterns, checklists, and links to Apple docs. There are no commands, file reads/writes, or network endpoints (other than benign Apple doc URLs) and nothing that instructs the agent to collect or transmit user data.

Install Mechanism

No install spec and no code files that execute — the skill is instruction-only, so it doesn't download or write code to the host. This is the lowest-risk install profile.

Credentials

The skill declares no environment variables, credentials, or config paths. That is proportionate for a documentation-and-snippets skill.

Persistence & Privilege

always:false and default model-invocation behavior are set. The skill does not request permanent presence or elevated system privileges and does not modify other skills or system-wide settings.

Assessment

This skill is coherent and low-risk: it only provides SwiftUI guidance and snippets for Apple’s Liquid Glass APIs and requires no installs or secrets. Before installing, consider provenance — the source/homepage is unknown and content is attributed as copied from a third party, so confirm licensing and trustworthiness if you will rely on it in production. Also: treat code snippets like any external sample code — review, test, and adapt them for your app (including availability guards for iOS versions) before copying into your codebase. If you prefer to prevent autonomous invocation by agents, adjust your agent/skill policy settings (this skill’s default allows autonomous invocation, which is normal but can be changed).

Overview

Use this skill to build or review SwiftUI features that fully align with the iOS 26+ Liquid Glass API. Prioritize native APIs (glassEffect, GlassEffectContainer, glass button styles) and Apple design guidance. Keep usage consistent, interactive where needed, and performance aware.

Workflow Decision Tree

Choose the path that matches the request:

1) Review an existing feature

• Inspect where Liquid Glass should be used and where it should not.
• Verify correct modifier order, shape usage, and container placement.
• Check for iOS 26+ availability handling and sensible fallbacks.

2) Improve a feature using Liquid Glass

• Identify target components for glass treatment (surfaces, chips, buttons, cards).
• Refactor to use GlassEffectContainer where multiple glass elements appear.
• Introduce interactive glass only for tappable or focusable elements.

3) Implement a new feature using Liquid Glass

• Design the glass surfaces and interactions first (shape, prominence, grouping).
• Add glass modifiers after layout/appearance modifiers.
• Add morphing transitions only when the view hierarchy changes with animation.

Core Guidelines

• Prefer native Liquid Glass APIs over custom blurs.
• Use GlassEffectContainer when multiple glass elements coexist.
• Apply .glassEffect(...) after layout and visual modifiers.
• Use .interactive() for elements that respond to touch/pointer.
• Keep shapes consistent across related elements for a cohesive look.
• Gate with #available(iOS 26, *) and provide a non-glass fallback.

Review Checklist

• Availability: #available(iOS 26, *) present with fallback UI.
• Composition: Multiple glass views wrapped in GlassEffectContainer.
• Modifier order: glassEffect applied after layout/appearance modifiers.
• Interactivity: interactive() only where user interaction exists.
• Transitions: glassEffectID used with @Namespace for morphing.
• Consistency: Shapes, tinting, and spacing align across the feature.

Implementation Checklist

• Define target elements and desired glass prominence.
• Wrap grouped glass elements in GlassEffectContainer and tune spacing.
• Use .glassEffect(.regular.tint(...).interactive(), in: .rect(cornerRadius: ...)) as needed.
• Use .buttonStyle(.glass) / .buttonStyle(.glassProminent) for actions.
• Add morphing transitions with glassEffectID when hierarchy changes.
• Provide fallback materials and visuals for earlier iOS versions.

Quick Snippets

Use these patterns directly and tailor shapes/tints/spacing.

if #available(iOS 26, *) {
    Text("Hello")
        .padding()
        .glassEffect(.regular.interactive(), in: .rect(cornerRadius: 16))
} else {
    Text("Hello")
        .padding()
        .background(.ultraThinMaterial, in: RoundedRectangle(cornerRadius: 16))
}

GlassEffectContainer(spacing: 24) {
    HStack(spacing: 24) {
        Image(systemName: "scribble.variable")
            .frame(width: 72, height: 72)
            .font(.system(size: 32))
            .glassEffect()
        Image(systemName: "eraser.fill")
            .frame(width: 72, height: 72)
            .font(.system(size: 32))
            .glassEffect()
    }
}

Button("Confirm") { }
    .buttonStyle(.glassProminent)
