When This Skill Activates

技能触发场景

Use this skill when the user:
  • Asks about Swift concurrency (async/await, actors, Sendable, TaskGroup)
  • Needs help with Swift 6 strict concurrency migration
  • Has data race or actor isolation errors
  • Asks about InlineArray, Span, or low-level memory performance
  • Wants to eliminate heap allocations or replace unsafe pointers
  • Asks about modern Swift patterns independent of any specific platform
当用户出现以下需求时，启用本技能：
  • 询问Swift并发相关内容（async/await、actors、Sendable、TaskGroup）
  • 需要Swift 6严格并发迁移的帮助
  • 遇到数据竞争或actor隔离错误
  • 询问InlineArray、Span或底层内存性能相关问题
  • 希望消除堆分配或替换不安全指针
  • 询问独立于特定平台的现代Swift编程模式

memory/

memory/

Swift 6.2 InlineArray and Span for low-level memory performance.
  • InlineArray: fixed-size, stack-allocated collections with zero heap overhead
  • Span family: safe, non-escapable access to contiguous memory
  • Lifetime dependencies and non-escapable type constraints
  • Performance guidance: when to use InlineArray/Span vs Array/UnsafePointer
用于底层内存性能优化的Swift 6.2 InlineArray与Span。
  • InlineArray：固定大小、栈分配的集合，无堆内存开销
  • Span系列：对连续内存的安全、非逃逸访问
  • 生命周期依赖与非逃逸类型约束
  • 性能指导：何时使用InlineArray/Span而非Array/UnsafePointer

How to Use

使用方法

  1. Identify user's need from their question
  2. Read relevant module files from subdirectories
  3. Apply the guidance to their specific context
  4. Cross-reference with platform-specific skills (ios/, macos/) as needed
  1. 从用户问题中识别其需求
  2. 读取子目录中的相关模块文件
  3. 将指导内容应用到用户的具体场景中
  4. 必要时结合特定平台技能（ios/、macos/）进行交叉参考
