Modern Concurrency in Swift (First Edition) Introducing AsyncAwait, Task Groups Actors (Tutorial Team, raywenderlich, Todorov etc.)（Z-Library）

Author： Tutorial Team, raywenderlich, Todorov, Marin

Master Swift’s new concurrency model! For years, writing powerful and safe concurrent apps with Swift could easily turn into a daunting task, full of race conditions and unexplained crashes hidden in a massive nesting of callback closures. In Swift 5.5, Apple introduced a new concurrency model featuring the async/await syntax, to let you write asynchronous code that reads like synchronous code. But like any new feature, here be dragons! So how will you achieve the much-desired mastery of Modern Swift Concurrency? Master Swift’s new concurrency model! For years, writing powerful and safe concurrent apps with Swift could easily turn into a daunting task, full of race conditions and unexplained crashes hidden in a massive nesting of callback closures. In Swift 5.5, Apple introduced a new concurrency model featuring the async/await syntax, to let you write asynchronous code that reads like synchronous code. But like any new feature, here be dragons! So how will you achieve the much-desired mastery of Modern Swift Concurrency? The new concurrency model provides everything you need to write safe and performant programs in Swift, including: • A new, native syntax for running asynchronous operations in a structured way. • A bundle of standard APIs to design asynchronous and concurrent code. • Low-level changes in the libdispatch framework, which make all the high-level changes integrate directly into the operating system. • A new level of compiler support for creating safe, concurrent code. Swift 5.5 introduces the new language syntax and APIs to support these features. In your apps, besides using a recent Swift version, you also need to target certain platform versions: • If you’re using Xcode 13.2 or newer, it will bundle the new concurrency runtime with your app so you can target iOS 13 and macOS 10.15 (for native apps). • In case you’re on Xcode 13 but earlier version than 13.2, you’ll be able to target only iOS 15 or macOS 12 (or newer).
