Is this limited to iOS development?

No, the guidelines cover all Apple platforms, including macOS, iPadOS, watchOS, tvOS, and visionOS.

Can it help with app performance issues?

Absolutely. It identifies anti-patterns like heavy View bodies and unnecessary re-renders, providing solutions like Lazy stacks and proper View identity management.

Does this skill support the latest SwiftUI features?

Yes, it includes patterns for modern APIs like NavigationStack (iOS 16+), @Observable (iOS 17+), and ContentUnavailableView (iOS 17+).

How does it handle state management?

It provides best practices for property wrappers like @State, @Binding, and @StateObject, emphasizing the Single Source of Truth (SSOT) principle and minimizing derived state.

Mobile Development

Provides comprehensive patterns and best practices for building high-performance, maintainable Apple platform apps using SwiftUI and Swift.

About

This skill acts as a specialized knowledge base for SwiftUI development, offering structured guidance on state management, navigation, and UI patterns across iOS, macOS, watchOS, and visionOS. It helps developers avoid common pitfalls like performance-draining AnyView usage or unstable View identities while enforcing architectural principles such as Single Source of Truth (SSOT) and the separation of concerns between logic and UI. Whether you are bootstrapping a new feature, implementing complex navigation flows, or optimizing view performance, this skill provides the implementation patterns and anti-patterns necessary for production-grade Apple development.

Key Features

Performance optimization strategies including Lazy stacks and Equatable views
Standardized patterns for UI features like infinite scroll and pull-to-refresh
Detailed anti-pattern identification to prevent common SwiftUI bugs
3 GitHub stars
Comprehensive implementation patterns for lists, forms, and navigation
Guidance on modern state management using @Observable and property wrappers

Use Cases

Designing complex navigation flows using NavigationStack and type-safe routing
Optimizing app performance by replacing AnyView and fixing unstable View identities
Implementing standardized form validation and search functionality with debouncing
