Build and review SwiftUI features using the iOS 26+ Liquid Glass API with native modifiers and Apple design guidance. \n \n Supports three workflows: reviewing existing features for correct Liquid Glass usage, improving features by refactoring to glass components, and implementing new glass-based UI from scratch \n Provides native API patterns including glassEffect() , GlassEffectContainer for grouped elements, and .buttonStyle(.glass) / .buttonStyle(.glassProminent) for actions \n Includes avai

Use this skill to build, review, or improve SwiftUI features with correct state management, optimal view composition, and iOS 26+ Liquid Glass styling. Prioritize native APIs, Apple design guidance, and performance-conscious patterns. This skill focuses on facts and best practices without enforcing specific architectural patterns.

Diagnose and fix SwiftUI performance issues through code review and Instruments profiling guidance. \n \n Classifies symptoms (slow rendering, janky scrolling, CPU spikes, memory growth, hangs, excessive view updates) and performs code-first review against common anti-patterns like invalidation storms, unstable list identity, and layout thrash. \n Guides users through Instruments profiling when code review alone is inconclusive, with structured intake checklists and trace analysis. \n Provides r

Comprehensive guide to SwiftUI's animation system, from foundational concepts to advanced techniques. This skill covers the Animatable protocol, the iOS 26 @Animatable macro, animation types, and the Transaction system.

SwiftUI debugging falls into three categories, each with a different diagnostic approach:

This skill encodes design principles derived from comparing polished, production-quality SwiftUI apps against poorly-built ones. The patterns here represent what separates an app that feels "right" from one where the margins, spacing, and text sizes just look "off."

SwiftUI Liquid Glass effects for iOS 26+ with interactive glass containers, morphing transitions, and button styles. \n \n Provides .glassEffect() modifier for applying translucent Liquid Glass material to custom views, with support for tinting, interactivity, and custom shapes \n Includes GlassEffectContainer for grouping and blending multiple glass elements, plus glassEffectID and glassEffectUnion for morphing animations during view hierarchy changes \n Offers pre-built button styles ( .glass

Advanced SwiftUI animations, transitions, matched geometry effects, and Metal shader integration for iOS and macOS. \n \n Covers animation curves, springs, keyframe animators, and phase animators for orchestrated multi-step sequences \n Includes built-in transitions (fade, slide, scale, move) and asymmetric transitions for directional entry/exit effects \n Provides matched geometry effect patterns for hero animations and smooth view transitions \n Supports GPU-accelerated Metal shader effects in
