What problem does it solve? Adopting Apple's iOS 26 Liquid Glass design language requires learning new APIs for glass materials, morphing transitions, and widget rendering modes, and this Skill provides the exact patterns needed to implement them correctly. ## Core Features & Use Cases - SwiftUI Glass Effects: Apply .glassEffect() with tint, shape, and interactive modifiers, plus GlassEffectContainer for merging and morphing multiple glass elements. - UIKit Integration: Use UIGlassEffect and UIGlassContainerEffect with UIVisualEffectView, scroll edge effects, and toolbar glass customization. - WidgetKit Support: Handle accented rendering modes, accent groups, and container backgrounds so widgets match tinted Home Screen appearances. - Use Case: When migrating an app's card-based UI to iOS 26, use this Skill to wrap cards in a GlassEffectContainer, add morphing transitions with @Namespace and glassEffectID, and avoid performance pitfalls from ungrouped glass views. ## Quick Start Use the liquid-glass-design skill to add a glass effect with a morphing transition to my SwiftUI toolbar buttons.
