Who This Book is For

 Aspiring iOS app developers familiar with the Apple Swift programming language and/or the iOS SDK, but ready to move to the next level.

 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, which lets 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?

 Modern Concurrency in Swift comes to the rescue, showcasing what you need to know about async/await, tasks, actors and everything in between!

Who This Book Is For

 This book is for intermediate Swift developers who are familiar with writing asynchronous applications and who want to leverage the concurrency features Apple introduced in Swift 5.5 and its evolution throughout the years, to write safer and more predictable asynchronous apps.

 Topics Covered in Modern Concurrency in Swift

• Using async/await: Learn how to use the new async/await keywords to define and run asynchronous work.
• Actors: Find out how to use the actor model to easily protect shared mutable state in a synchronized container.
• Tasks: You'll dive deeper into the Task type, which powers all asynchronous tasks in Swift's modern concurrency model.
• Task Groups: Use a Task Group to group multiple tasks together and run them concurrently, while using a familiar Array-like syntax to iterate over the results.
• Custom Asynchronous Sequences: Leverage the power of async/await in your own asynchronous work, by learning how to create custom AsyncStreams.
• Testing Asynchronous Code: Asynchronous code can be a challenging beast to test. You'll learn everything you need to tackle this challenge.

 One thing you can count on: After reading this book, you’ll be prepared to leverage Swift's new concurrency features in your app to write safe, performant and predictable asynchronous code.

What will you learn from this book?

 Swift is best known as Apple's programming language of choice for developing apps on iOS, iPadOS, macOS, watchOS, and tvOS. But it's far more versatile than that. Open source Swift is also gaining ground as a language for systems programming and server-side code, and it runs on Linux and Windows. So where do you start? With Head First Swift, you'll explore from the ground up: from collecting and controlling data to reusing code, producing custom data types, and structuring programs and user interfaces with SwiftUI by building safe, protocol-driven code. With Swift under your belt, you'll be ready to build everything from mobile and web apps to games, frameworks, command-line tools, and beyond.

What's so special about this book?

 If you've read a Head First book, you know what to expect--a visually rich format designed for the way your brain works. If you haven't, you're in for a treat. With this book, you'll learn Swift through a multisensory experience that engages your mind rather than a text-heavy approach that puts you to sleep.

 Develop well-structured applications using tested techniques and patterns. When you start to develop an application, you not only have to think about the idea of the finished application, but also about how it will evolve as it is built. This book shows you how to plan for changes, scope creep, and for the possibility of other developers joining in. 

 Start by learning what architecture patterns for an application are. You’ll find out why it’s important for your applications to be based on these patterns and which ones are the most common. Then you’ll look at the MVC as one of the best known and used patterns. You’ll see how and when it can be implemented in your applications, as well as its advantages and disadvantages. 

 From there, you’ll discover the first evolution of the MVC model: the MVP, which introduces a new layer (Presenter) to better manage views. The next evolution after that is the MVVM, which introduces the ViewModel layer and its connection with the views through Data Binding. With those prominent patterns covered, you’ll read about VIPER and VIP, Architecture Patterns that seeks to make applications easily maintainable, modularized, and highly scalable. All of which are hallmarks of Clean Architecture.  

 Architecture patterns have developed and evolved to give your applications solid foundations. Understanding these patterns, you will reduce the problems that may arise when modifying existing functions, adding new ones, or correcting errors that may arise in the development process.

What You'll Learn

• Code cleanly with solid foundations
• Start your project ready to adapt and evolve as features and other developers are added 
• Find and apply the right patterns for the best results  

 Who This Book Is ForDevelopers with some programming knowledge who want to learn different architecture patterns, those who already have more experience and are looking for a starting point on complex patterns such as VIPER or VIP, and beginner programmers.

Writing asynchronous code can be challenging, with a variety of possible interfaces to represent, perform, and consume asynchronous work — delegates, notification center, KVO, closures, etc. Juggling all of these different mechanisms can be somewhat overwhelming. Does it have to be this hard? Not anymore!

In this book, you'll learn about Combine — Apple’s framework to work with asynchronous events in a unified and reactive way that ensures your app is always up to date based on the latest state of its data.

Who This Book Is For

This book is for intermediate iOS developers who already know the basics of iOS and Swift development but are interested in learning declarative/reactive programming and take their app and state management to the next level.

You'll also find this book interesting if you're interested in SwiftUI — as many of the reactive capabilities keeping your SwiftUI views up-to-date are built on top of Combine.

Topics Covered in Combine: Asynchronous Programming with Swift

• What & Why: Learn what is Combine and reactive programming and the problems they solve, and how you can unify all of your asynchronous piece of work.
• Operators: Learn how to compose, transform, filter and otherwise manipulate different pieces of asynchronous work using operators.
• In Practice: You'll gain knowledge on various topics and techniques you'll leverage when writing your own real-life apps, as well as practice these techniques with actual hands-on apps and projects.
• SwiftUI: You'll learn about how Combine is deeply rooted within SwiftUI and provides it with the ability to reactively update its views based on the state of your app.
• Advanced Combine: Once you've got a handle on the basics, you'll dive into advanced Combine topics such as Error Handling, Schedulers, and Custom Publishers.

By the end of this book, you'll be a pro in building full-fledged applications using Combine's various abilities.

 This book is for iOS developers who already feel comfortable with iOS and Swift, and want to dive deep into development with RxSwift.

 If you’re a complete beginner to iOS, we suggest you first read through the latest edition of the iOS Apprentice. That will give you a solid foundation of building iOS apps with Swift from the ground up but you might still need to learn more about intermediate level iOS development before you can work through all chapters in this book.

 If you know the basics of iOS development but are new to Swift, we suggest you read through Swift Apprentice first, which goes through the features of Swift using playgrounds to teach the language.

 This book is for intermediate or advanced iOS developers who already know the basics of iOS and Swift development but want to learn about the new APIs, frameworks, and changes in Xcode 9 and iOS 11.

•  If you are a complete beginner to iOS development, we recommend you read through The iOS Apprentice, Fifth Edition first. Otherwise this book may be a bit too advanced for you.
• If you are a beginner to Swift, we recommend you read through either The iOS Apprentice, Fifth Edition (if you are a complete beginner to programming), or The Swift Apprentice, Second Edition (if you already have some programming experience) first.

 This book assumes you may have never programmed before. The book is also written for someone who may have never programmed before using object-oriented programming (OOP) languages. There are many Swift books out there, but all of these books assume you have programmed before and know OOP and computer logic. We wanted to write a book that takes readers from knowing little or nothing about computer programming and logic to being able to program in Swift. After all, Swift is a native programming language for the iPhone, iPad, and Mac.

 Over the last eight years, we have taught thousands of students at xcelMe.com to be iOS (iPhone/iPad) developers. Many of our students have developed some of the most successful iOS apps in their category in the App Store. We have incorporated what we have learned in our first two courses, Introduction to Object-Oriented Programming and Logic and Swift for iPhone/iPad Developers, into this book.
