Swift Concurrency (async/await, structured concurrency, actors) is Apple's modern approach to handling concurrent code safely. Used by iOS developers, macOS developers, and Swift backend engineers. Time to learn: 8–12 weeks. Sits between Swift fundamentals and advanced concurrent systems.

什么是 Swift Concurrency Async

Swift Concurrency is Apple's modern concurrency framework introduced in Swift 5.5 (iOS 15+). It includes async/await (for writing asynchronous code that reads sequentially), structured concurrency (tasks, task groups, cancellation), and actors (for safe mutable state in concurrent code). Unlike callbacks or Combine, async/await makes concurrent code read like synchronous code. Threads are managed automatically; developers focus on what to do, not how to manage threads.

❓ 常见问题

What's the difference between async/await and Combine?

async/await is simpler, sequential code that looks like synchronous code. Combine is reactive, functional, and more powerful for complex event streams. Use async/await for simple async calls; use Combine for reactive pipelines.

Are actors a replacement for thread safety?

Actors ensure thread-safe access to mutable state. They don't eliminate threading; they make it safe. Always access actor's state through await.

Can you mix async/await with Combine?

Yes, you can wrap Combine publishers in async/await, and vice versa. But mixing is often unnecessary. Choose one paradigm per feature.

How do you handle errors in async code?

Use do-catch blocks in async functions. Throw errors like synchronous code. async/await makes error handling cleaner than callbacks or Combine.

What's the performance impact of async/await?

Minimal, async/await is compiled away. Performance is comparable to callbacks but with much cleaner code. No overhead vs. Combine for simple cases.
