Along the way, you’ll learn several ways to execute Swift code and you’ll build two fully featured apps from scratch.

If you’re new to macOS and Swift, or to programming in general, learning how to write an app can seem incredibly overwhelming.

That’s why you need a guide that:

Shows you how to write an app step-by-step. Uses tons of illustrations and screenshots to make everything clear. Guides you in a fun and easy-going manner.

You’ll start at the very beginning. The first section assumes you have little to no knowledge of programming in Swift. It walks you through installing Xcode and then teaches you the basics of the Swift programming language. Along the way, you’ll explore several different ways to run Swift code, taking advantage of the fact that you’re developing natively on macOS.

macOS Apprentice doesn’t cover every single feature of macOS; it focuses on the absolutely essential ones. Instead of just covering a list of features, macOS Apprentice does something much more important: It explains how all the building blocks fit together and what is involved in building real apps. You’re not going to create quick example programs that demonstrate how to accomplish a single feature. Instead, you’ll develop complete, fully-formed apps, while exploring many of the complexities and joys of programming macOS.

Combine: Asynchronous Programming With Swift

Learn all about declarative asynchronous programming with Swift using the Combine framework!

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 really have to be this hard? Not anymore!

With Apple’s introduction of the Combine framework in WWDC 2019, declarative and reactive programming in Swift have become a meaningful aspect of the language and a game-changer in how developers perform and compose pieces of asynchronous work, making it a must-have tool at your disposal.

The introduction of Combine as a built-in framework in Apple’s ecosystem is promising news to developers who were interested in frameworks such as RxSwift or ReactiveSwift, but didn’t want the overhead of a third-party dependency. And while experience with either of the above is useful, it’s not a prerequisite for this book. You’ll learn everything from the ground up to become a true Combine master.

What Is Combine?

Combine is 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.

What are these asynchronous events, you might ask? Anything that happens over time in your application can be represented by what is known as a Combine Publisher — network requests, user input, notifications, KVO, and much more. And since Combine unifies all of these different mechanisms under a single interface, this opens the door to interesting and powerful ways of composing logic and work in a declarative and universal way.

SwiftUI by Tutorials

Build fluid and engaging declarative UI for your apps — using less code — with SwiftUI!

SwiftUI by Tutorials is designed to help you learn how to transition from the “old way” of building your app UI with UIKit, to the “new way” of building responsive UI with modern declarative syntax with SwiftUI. This book is for readers who are comfortable building Swift apps, and want to make the exciting leap into building their app UI with modern, declarative code.

What is SwiftUI?

SwiftUI lets you build better apps, faster, and with less code. It’s a developer’s dream come true! With SwiftUI, you can design your user interfaces in a declarative way; instead of developing app interfaces in an imperative way, by coding all of the application state logic before time, you can instead define what your app’s UI should do in a particular state and let the underlying OS figure out how to do it. What’s more is that SwiftUI lets you build modern, responsive UI and animations for all Apple devices — not just iOS. So whether you’re building apps for iOS, watchOS, tvOS or any other Apple platform, you can use the same concise, natural language to describe your UI and have it look stunning — no matter where your code runs. In addition, SwiftUI’s built-in automatic support for things such as dark mode, localization and accessibility, along with Xcode 11 support for drag-and-drop design and instant preview makes it easier to build apps than ever before.

How is this book different than SwiftUI Apprentice?

Our other book on getting started with SwiftUI, SwiftUI Apprentice, is designed to teach new developers how to build iOS apps, using a SwiftUI-first approach. The goal of that book is to teach you fundamental development practices as you build out some fully-functional and great-looking apps!

Modern Concurrency in Swift

Master Swift’s modern 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?

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

SwiftUI Animations by Tutorials

Drive SwiftUI into Motion using Animations!

SwiftUI has absolutely changed our lives when it comes to developer experience and developer productivity. We can make beautiful apps extremely quickly, get instant feedback from SwiftUI previews, and iterate. SwiftUI also enables developers to easily leverage most common animations using simple SwiftUI modifiers, which makes it a pleasure to use. But it also begs the question: “How do I make my app stand out if everyone is using the same standard animations?”

Luckily, SwiftUI Animations by Tutorials is here to help you learn how to create detailed and delightful animations, starting from the basics and up to the most complex and customizable ones.

Push Notifications by Tutorials

Get Started with Push Notifications on iOS!

Push notifications may seem simple and straightforward at first since almost everyone is familiar with them; however, knowing how and when to use them in practice can prove challenging.

With advancements in the latest iOS releases bringing advanced features, such as rich media notifications, notification actions, grouped notifications and more, you will quickly realize that you need a book to help you out. Well, here’s that book!

You’ll learn everything you need in order to create, send and receive push notifications, meaning notifications that come from an external service, as opposed to locally from the device. You’ll also cover how to handle local notifications because, sometimes you don’t need all the overhead of a remote notification; rather, it’s enough to simply schedule a notification to appear at a specific point in the future or when you enter a specific location.

Since push notifications is such a focused subject, this book is direct and to-the point; instead of wading through 300 pages of theory before getting down to business, the book gets the job done in just over 150 pages. It’s just the information you need, just when you need it.

By the end of this book, you’ll be a master of push notifications and well on your way to implementing them inside your own apps!

Catalyst by Tutorials

Metal by Tutorials

Build your own low-level game engine in Metal!

Metal is a unified application programming interface (API) for the graphics processing unit, or GPU. It’s unified because it applies to both 3D graphics and data-parallel computation paradigms. Metal is a low-level API because it provides programmers near-direct access to the GPU. Finally, Metal is a low-overhead API because it reduces the central processing unit (CPU) cost by multi-threading and pre-compiling of resources.

But beyond the technical definition, Metal is the most appropriate way to use the GPU’s parallel processing power to visualize data or solve numerical challenges. It’s also tailored to be used for machine learning, image/video processing or, as this book describes, graphics rendering.

This book will introduce you to low-level graphics programming in Metal — Apple’s framework for programming on the graphics processing unit (GPU). As you progress through this book, you’ll learn many of the fundamentals that go into making a game engine and gradually put together your own engine. Once your game engine is complete, you’ll be able to put together 3D scenes and program your own simple 3D games. Because you’ll have built your 3D game engine from scratch, you’ll be able to customize every aspect of what you see on your screen.

Kotlin Coroutines by Tutorials

The importance of concurrency is discovered quite early on by people who start with Android development. Android is inherently asynchronous and event-driven, with strict requirements as to on which thread certain things can happen.

Add to this the often-cumbersome Java callback interfaces, and you will be trapped in spaghetti code pretty quickly (aptly termed as “Callback Hell”). No matter how many coding patterns you use to avoid that, you will have to encounter the state change across multiple threads in one way or the other.

The only way to create a responsive app is by leaving the UI thread as free as possible, letting all the hard work be done asynchronously by background threads.

Kotlin Coroutines by Tutorials will teach you the techniques you need to solve common programming problems using asynchronous programming.

Functional Programming in Kotlin by Tutorials

Functional programming is a powerful paradigm for building your applications. This book will teach you the fundamentals of functional programming in a practical, hands-on way, while showing you how you can safely handle errors and state changes in your programs.
