Swift Concurrency: A Practical Guide from GCD to Actors

Swift Concurrency is Apple’s modern concurrency model introduced to make asynchronous and concurrent programming safer, clearer, and easier to reason about. This article walks through Swift Concurrency from a practical perspective, comparing it with Grand Central Dispatch (GCD) and covering async/await, parallelism, asynchronous sequences, tasks, task groups, cancellation,
