# Liquid Glass Design Implement Apple's Liquid Glass design language across all Apple UI frameworks. Covers SwiftUI (`.glassEffect()`), AppKit (`NSGlassEffectView`), UIKit (`UIGlassEffect` + `UIVisualEffectView`), and WidgetKit (rendering modes, accented content, glass elements in widgets). ## When This Skill Activates - User wants glass/blur effects on views - User asks about Liquid Glass or modern Apple design - User needs transparent, interactive UI elements - User wants morphing transitions between views - User is implementing glass effects in UIKit with `UIVisualEffectView` - User needs `UIGlassEffect` or `UIGlassContainerEffect` - User asks about scroll view edge effects in UIKit - User wants Liquid Glass in widgets (WidgetKit) - User needs to support accented rendering mode in widgets - User asks about widget textures or mounting styles on visionOS ## Design Rules (WWDC25) Liquid Glass is the material of the **navigation layer** — bars, toolbars, floating controls — never the content layer (tables, lists, rows in a scroll view). | Rule | Detail | |------|--------| | **Never glass on glass** | Don't stack glass. Elements sitting ON glass don't get the material again — style them with fills and vibrancy. | | **Two variants — never mix them** | **Regular** (default): works at any size, over anything, with adaptive legibility. **Clear**: only when ALL three hold — media-rich content underneath, a dimming layer is acceptable, and bold bright content sits above.
