What problem does it solve? Adopting Apple's iOS 26 Liquid Glass design language requires learning new APIs across SwiftUI, UIKit, and WidgetKit, and developers often misapply glass effects in ways that hurt performance or break tinted widget appearances. ## Core Features & Use Cases - SwiftUI Glass Patterns: Apply .glassEffect() with tint, shape, and interactive modifiers, plus GlassEffectContainer for merging and morphing multiple glass elements. - UIKit Integration: Use UIGlassEffect, UIGlassContainerEffect, scroll edge effects, and toolbar glass configuration for UIKit-based views. - WidgetKit Support: Handle accented rendering modes, accent groups, and container backgrounds so widgets match tinted Home Screen appearances. - Use Case: When building an iOS 26 app toolbar with morphing glass buttons, use the provided GlassEffectContainer and glassEffectID patterns to animate elements smoothly as they appear and disappear. ## Quick Start Ask the assistant to add a Liquid Glass effect to a SwiftUI button group with morphing transitions using the iOS 26 glassEffect APIs.
