### Daniel H Steinberg

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 in to how and when you should use them and 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.

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.

_This work was written and produced entirely by the author. We are proud to be distributing it._
