swift-concurrency

Swift 并发编程的最佳实践与模式，涵盖 async/await、actor、task 以及 Sendable 协议的实现。适用于以下场景：(1) 编写 async/await 代码；(2) 实现 actor 或隔离域；(3) 使用结构化并发或任务组；(4) 确保 Sendable 协议的合规性与数据竞争的安全性；(5) 迁移到严格的并发检查机制；(6) 调试或测试异步代码；(7) 在异步上下文中管理内存。

description: "Swift Concurrency best practices and patterns for async/await, actors, tasks, and Sendable conformance. Use when: (1) writing async/await code, (2) implementing actors or isolation domains, (3) working with structured concurrency or task groups, (4) ensuring Sendable conformance and data race safety, (5) migrating to strict concurrency checking, (6) debugging or testing async code, (7) managing memory in async contexts."

Swift Concurrency Patterns

Expert guidance on Swift Concurrency best practices covering async/await, actors, tasks, Sendable, threading, memory management, testing, and migration strategies.
