iOS Development Guidelines

iOS开发指南

Swift and SwiftUI Fundamentals

Swift与SwiftUI基础

  • Use Swift 5.9+ with modern language features
  • Prefer SwiftUI for new UI components
  • Use property wrappers (@State, @Binding, @ObservedObject, @StateObject) appropriately
  • Leverage async/await for asynchronous operations
  • Use Swift concurrency actors for thread-safe code
  • Follow Swift API design guidelines
  • 使用Swift 5.9+及现代语言特性
  • 优先为新UI组件使用SwiftUI
  • 合理使用属性包装器（@State、@Binding、@ObservedObject、@StateObject）
  • 利用async/await处理异步操作
  • 使用Swift并发actor实现线程安全代码
  • 遵循Swift API设计指南

UIKit and AppKit Patterns

UIKit与AppKit模式

  • Maintain compatibility with UIKit where needed
  • Use view controllers with proper lifecycle management
  • Implement Auto Layout constraints correctly
  • Use delegation and notification patterns appropriately
  • Handle memory management with ARC best practices
  • Use storyboards and XIBs sparingly; prefer programmatic UI
  • 在需要时保持与UIKit的兼容性
  • 使用具备正确生命周期管理的视图控制器
  • 正确实现Auto Layout约束
  • 合理使用委托与通知模式
  • 遵循ARC最佳实践处理内存管理
  • 尽量少用故事板（storyboards）和XIB；优先采用程序化UI

iOS Architecture Patterns

iOS架构模式

  • MVVM: Use for SwiftUI-based applications
  • MVC: Use for UIKit-based applications
  • Coordinator: Use for complex navigation flows
  • Implement dependency injection for testability
  • Separate business logic from UI code
  • Use protocols for abstraction and testing
  • MVVM：用于基于SwiftUI的应用
  • MVC：用于基于UIKit的应用
  • Coordinator：用于复杂导航流程
  • 实现依赖注入以提升可测试性
  • 将业务逻辑与UI代码分离
  • 使用协议进行抽象与测试

Core Data and Persistence

Core Data与持久化

  • Use Core Data for complex data models
  • Consider SwiftData for SwiftUI applications
  • Use UserDefaults for simple key-value storage
  • Implement proper data migration strategies
  • Use background contexts for heavy operations
  • Follow Core Data best practices for performance
  • 为复杂数据模型使用Core Data
  • 对于SwiftUI应用可考虑使用SwiftData
  • 为简单键值存储使用UserDefaults
  • 实现合理的数据迁移策略
  • 为重型操作使用后台上下文
  • 遵循Core Data性能最佳实践

iOS Frameworks

iOS框架

  • Combine: Use for reactive programming
