Does it support the latest SwiftUI features?

Yes, it includes specific checks for iOS 17+ property wrappers like @Observable and @Bindable, as well as modern .task modifiers.

When should I use the references provided in the skill?

References should be loaded when Claude identifies complex view bodies, incorrect property wrapper usage, or identity issues in Lists.

What specifically does this skill check for in SwiftUI?

It audits view composition, modifier order, state management patterns, scrolling performance, and accessibility compliance.

Can it catch accessibility issues?

Yes, it verifies that images have labels, custom controls have the correct traits, and that the UI supports Dynamic Type without fixed font sizes.

How does it help with app performance?

It identifies performance bottlenecks like AnyView usage, inefficient list rendering, and suggests LazyStacks for large datasets.

Mobile Development

Analyzes SwiftUI source code to ensure optimal view composition, efficient state management, and high accessibility standards.

About

This skill provides an automated, expert-level review framework for Apple's SwiftUI framework, focusing on production readiness and best practices. It evaluates view hierarchies to prevent over-complexity, validates property wrapper usage for state management (including modern @Observable patterns), optimizes performance via lazy stacks and identity management, and ensures inclusivity through VoiceOver and Dynamic Type checks. It is an essential tool for developers aiming to maintain high-quality iOS, macOS, and watchOS codebases using Claude Code.

Key Features

Performance Optimization (LazyStack usage and stable ForEach ID identification)
Modern Async Workflow Verification (proper usage of .task over onAppear + Task)
View Composition Analysis (complexity, modifier ordering, and subview extraction)
State Management Validation (@State, @Binding, @Observable, and @Bindable patterns)
14 GitHub stars
Accessibility Auditing (VoiceOver labels, traits, and Dynamic Type support)

Use Cases

Ensuring mobile applications meet accessibility standards and provide high-quality VoiceOver support.
Refactoring legacy SwiftUI code to utilize modern iOS 17+ observation patterns.
Automated pull request reviews for mobile teams to maintain consistent code standards.
