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

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."

A packaged set of Apple-authored AdditionalDocumentation shipped inside Xcode, plus prompts that enforce Apple-native patterns and reduce hallucinations.

Modern SwiftUI patterns for iOS 26+ with MV architecture, state management, and view composition. \n \n Covers @Observable ownership rules, @State / @Bindable / @Environment wiring, and view decomposition best practices for clean, performant UIs \n Includes async data loading with .task , custom ViewModifier styling, environment value patterns, and granular state tracking that only re-renders affected views \n Provides iOS 26+ API updates (scroll edge effects, background extensions, @Animatable
