SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Streamlines SwiftUI development by enforcing up-to-date state-management, clean view composition, performance-conscious patterns, and iOS 26 Liquid Glass readiness.

Core Features & Use Cases

Establishes a consistent approach to using @Observable for state and modern API replacements.
Guides in extracting complex views, optimizing diffing, and applying stable identities in lists.
Provides explicit guidance for adopting Liquid Glass patterns and availability fallbacks.
Useful for building new SwiftUI features, refactoring existing views, or reviewing code quality.

Quick Start

Scan a sample SwiftUI view to identify opportunities for improvement and apply concrete recommendations for state management, view structure, and iOS 26 Liquid Glass adoption.

FAQPage Schema

How do I migrate SwiftUI state management to use @Observable?▼

Migrating SwiftUI state management to @Observable involves replacing ObservableObject conformances with the @Observable macro, which establishes modern state tracking and reduces unnecessary view updates during feature development and refactoring.

What is the best way to optimize SwiftUI view diffing and list performance?▼

The best way to optimize SwiftUI view diffing and list performance is by applying stable identities in lists and systematically extracting complex views into smaller components, which streamlines the diffing process and enforces performance-conscious patterns.

How do I prepare my SwiftUI app for iOS 26 Liquid Glass?▼

To prepare your SwiftUI app for iOS 26 Liquid Glass, adopt specific Liquid Glass patterns and implement explicit availability gating with fallbacks, ensuring your views maintain visual stability across older operating system versions.

Can I use this approach for SwiftUI code reviews?▼

Yes, you can use this approach for SwiftUI code reviews to systematically evaluate state management, view structure, and performance, applying concrete recommendations to ensure modern API usage and stable view identities.

When should I use explicit availability gating in SwiftUI?▼

Use explicit availability gating in SwiftUI when adopting modern API replacements and iOS 26 Liquid Glass readiness, providing fallbacks to ensure consistent behavior across different operating system versions.
