Asynchronous Swift (iOS/macOS): The Complete Guide

Asynchronous programming is one of the most complex topics in iOS and macOS development. Mistakes in thread management lead to interface freezes, memory leaks, and hard-to-find bugs. The book "Asynchronous Swift (iOS/macOS): The Complete Guide" fills all the gaps — from basic principles to advanced patterns available in Swift 5.9 and later.

The author of the book is Alexey Voronov, a senior iOS developer with 10 years of experience and a contributor to Apple open-source projects. The book contains no fluff: only practice, real-world cases, and clear explanations.

What you will learn:

• Swift Concurrency Basics: async/await, structured concurrency, Task and TaskGroup.
• Actors: how to protect data from races without locks, isolation and reentrancy.
• Combine vs AsyncSequence: when to choose the reactive approach and when to use asynchronous sequences.
• Working with the UI: how to properly update the interface from background threads, @MainActor and Sendable.
• Network Requests and Databases: URLSession with async/await, Core Data and SwiftData in an asynchronous context.
• Testing Asynchronous Code: XCTestExpectation, async tests, mocks and stubs.
• Advanced Patterns: actor-based architecture, async let, unstructured tasks and operation cancellation.

Who this book is for:

• iOS/macOS developers who want to transition from GCD (Grand Central Dispatch) to modern Swift Concurrency.
• Juniors and mid-level developers facing multithreading issues in real projects.
• Tech leads and architects looking for reliable ways to organize asynchronous code in large applications.
• Anyone using SwiftUI or UIKit who wants to write fast and safe code without interface freezes.

Why you should buy it:

• Up-to-date: the book is written for Swift 5.9+ and Xcode 15, all examples work out of the box.
• Practical focus: 200+ pages of code, ready-made projects, and checklists for refactoring legacy code.
• Accessibility: even if you have never worked with asynchrony, the first chapters will smoothly introduce you to the topic.
• Support: the book comes with a repository of examples and answers to readers' questions.

After reading, you will be able to confidently design asynchronous systems in Swift, avoiding deadlocks, race conditions, and unnecessary complexity. The book will become your go-to reference for concurrency in the Apple ecosystem.
