The Curious Case of the Async Cafe »

Swift’s new async/await family is a language level solution for asynchronous and concurrent code. This book introduces the new keywords and additions to the Swift Standard Library, digs into how and when you should use them, and tells you what pitfalls to avoid. You'll learn to replace traditional approaches to working with callbacks and concurrency with simpler code that is easier to read and reason about.

The Curious Case of the Async Cafe: An Introduction to Modern Concurrency in Swift

Swift's solution to asynchronous and concurrent code is now part of the language itself. The new syntax, which in the past was complicated, fragmented, or deeply nested, is easier to read and follows a logical flow. With async/await you'll focus on tasks instead of threads or even queues.

The Curious Case of the Async Cafe is a quirky, fast-paced tour of the components of modern concurrency in Swift: async; await; Tasks; using continuations to replace and wrap delegates and closure-based APIs; AsyncSequences and AsyncStreams; structured concurrency using async let and Task Groups; and, of course, actors.
