SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides best practices and modern patterns for Swift and iOS development, ensuring code is efficient, maintainable, and up-to-date with the latest Apple technologies.

Core Features & Use Cases

  • Modern Concurrency: Leverages Swift 6+ concurrency features like async/await and actors.
  • SwiftUI Best Practices: Guides on state management (@Observable), layout, and modern modifiers.
  • Code Organization: Recommends extension-based grouping and feature-centric file structures.
  • Use Case: When building a new iOS app feature, use this Skill to ensure your SwiftUI views are structured correctly, state is managed efficiently with @Observable, and all asynchronous operations are handled safely with modern concurrency.

Quick Start

Apply modern Swift concurrency patterns to the provided asynchronous function.

FAQPage Schema
How do I manage state in SwiftUI using the @Observable macro?

To manage SwiftUI state with @Observable, apply the macro to your model classes instead of using ObservableObject. This modern approach streamlines state management, ensuring your views update efficiently while adhering to Apple Human Interface Guidelines.

What is the best way to handle asynchronous operations in Swift 6?

The best way to handle asynchronous operations in Swift 6 is leveraging modern concurrency features like async/await and actors. This approach enforces safe concurrent execution, preventing data races and simplifying complex asynchronous code structures.

Can I use UIKit while following modern iOS development patterns?

No, you should avoid UIKit when following modern iOS development patterns. This approach enforces SwiftUI for user interfaces and avoids third-party frameworks unless explicitly approved, prioritizing native Apple technologies for maintainable code.

How do I organize Swift files for a new iOS app feature?

Organize Swift files for iOS features using extension-based grouping and feature-centric file structures. This method optimizes code organization by grouping related functionality together, improving maintainability and readability across your application.

Does modern Swift development require third-party frameworks?

Modern Swift development does not require third-party frameworks, as the approach avoids them unless explicitly approved. It leverages native Apple technologies like SwiftData and SwiftUI to ensure code remains efficient, maintainable, and up-to-date.
