iOS & Swift Books

Git Apprentice

Learn Git!

Chances are if you’re involved with software development you’ve heard of and have used Git at some point in your life. Version control systems are critical for any successful collaborative software project. Git is both simple to start using and accommodating for the most complex tasks with version control. Even seasoned Git users hit roadblocks on how to handle common situations.

Git Apprentice is here to help! This book is the easiest and fastest way to get hands-on experience with using Git for version control of your projects.

Who This Book Is For

This book is for anyone who would like to leverage the power of version control with Git in their software development process. The book starts with a gentle introduction to Git. It then moves on to walk you through creating a new repository, cloning an existing one, merging in changes, and all of the bits in between.

Topics Covered in Git Apprentice A Crash Course in Git: Learn how to get started with Git, the differences between platforms, and a quick overview of the typical Git workflow. Cloning a Repo: Discover how to clone a remote repo to your local machine, and what constitutes “forking” a repository. Git Log & History: You’ll discover the versatility of the git log command—displaying branches, graphs and even filtering the history. Creating a Repository: If you are starting a new project, and want to use Git for source control, you first need to create a new repository. And more!

One thing you can count on: after reading this book, you’ll be well-prepared to use Git in your own software development workflow!

SwiftUI Apprentice

SwiftUI Apprentice is a series of epic-length tutorials where you’ll learn to build three complete apps from scratch, using Apple’s new user interface technology: SwiftUI! Each app is more advanced than the one before, and together, they cover everything to make your own apps using SwiftUI. By the end of the book, you’ll be experienced enough to turn your ideas into real apps you can sell on the App Store. These tutorials have easy to follow step-by-step instructions and consist of more than pages and illustrations! You also get full source code, image files, and other resources you can re-use for your own projects.

If you’re new to iOS 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 for iOS but still shows you how to build an entire fitness app from scratch using SwiftUI. SwiftUI Apprentice doesn’t cover every single feature of iOS; it focuses on the absolutely essential ones. Instead of just covering a list of features, SwiftUI 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, with beautiful, professionally-designed user interfaces, that are good enough to submit to the App Store!

How is this book different than SwiftUI by Tutorials?

Our other book on building apps with SwiftUI, SwiftUI by Tutorials, is designed for developers who have a solid background in iOS development and are looking to make the leap from building apps with UIKit, to building apps with SwiftUI.

This book, SwiftUI Apprentice, is designed to teach new developers how to build iOS apps, using a SwiftUI-first approach. Its goal is to teach you fundamental development practices as you build out some fully-functional and great-looking apps!

Swift Apprentice: Beyond the Basics

Swift Apprentice: Beyond the Basics is the sequel to Swift Apprentice: Fundamentals and explores additional Swift programming concepts. These topics include such things as access control, code organization, testing, property wrappers, result builders, concurrency, value semantics, and memory management, presenting them using interactive playgrounds that the reader can follow along with.

Swift Apprentice: Fundamentals

This is a book for complete beginners to Apple’s modern programming language — Swift.

All the code in the book works inside of Xcode’s easy-to-use playgrounds. That means you can focus on core Swift language concepts, such as classes, protocols, and generics without getting bogged down by extraneous details.

This is a companion book to the SwiftUI Apprentice; the SwiftUI Apprentice focuses on building apps, while Swift Apprentice focuses on the Swift language itself.

Living by the Code

Living by the Code brings the experiences and insights of over 40 of today’s top developers, leaders and innovators in tech together in one single book, to help you grow your career in today’s ever-changing technical landscape. It’s like having dozens of tech’s best mentors — right at your fingertips.

Data Structures & Algorithms in Swift

Understanding how data structures and algorithms work in code is crucial for creating efficient and scalable apps and acing job interviews. Swift’s standard library and, more recently, the Swift Collections and Algorithms packages contain a robust set of general-purpose collection types and algorithms, yet they don’t cover every case!

In Data Structures and Algorithms in Swift, you’ll learn how to implement the most popular and useful data structures and when and why you should use one particular data structure or algorithm over another. This set of basic data structures and algorithms will serve as an excellent foundation for building more complex and special-purpose constructs. The high-level expressiveness of Swift makes it an ideal choice for learning these core concepts without sacrificing performance.

You’ll start with the fundamental structures of linked lists, queues and stacks, and see how to implement them in a highly Swift-like way. Move on to working with various types of trees, including general purpose trees, binary trees, AVL trees, binary search trees, and tries. Go beyond bubble and insertion sort with better-performing algorithms, including mergesort, radix sort, heap sort, and quicksort. Learn how to construct directed, non-directed and weighted graphs to represent many real-world models. Traverse those graphs and trees efficiently with breadth-first, depth-first, Dijkstra’s and Prim’s algorithms to solve problems such as finding the shortest path or lowest cost in a network.

By the end of this book, you’ll have hands-on experience solving common issues with data structures and algorithms — and you’ll be well on your way to developing your own efficient and useful implementations!

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.

This book is for intermediate Swift developers interested in learning 3D graphics or gaining a deeper understanding of how game engines work.

Kotlin Multiplatform by Tutorials

The best book to teach you how to share code across platforms using Kotlin Multiplatform. You’ll gain the foundation of creating user interfaces using native UI toolkits and then writing common code for serialization, networking and persistence. You’ll also learn how dependency injection, testing and different architectures fit in with Kotlin Multiplatform so that you build maintainable and scalable apps for the real world.

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! This book, SwiftUI by Tutorials, is designed for developers who have a solid background in iOS development, and are looking to make the leap from building apps with UIKit, to building apps with SwiftUI.

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

Run iOS apps Natively on macOS With Catalyst!

Catalyst by Tutorials shows you how to take all of those great apps you’ve built on iOS and run them right on macOS. But like everything else with Apple, it’s not always as straightforward as you’d like it to be. This book will show you how to design your apps to work well on macOS, what you can and can’t port between the two platforms, and any other “gotchas” to keep an eye out for when building apps under Catalyst.

This book is for developers who have a good handle on building iOS apps and want to learn how to port those apps to run on macOS as well.

What is Catalyst?

Formerly known as Marzipan to Apple insiders, Catalyst lets you extend your iPad apps to macOS. Under Catalina and Xcode 11, developers can start building their iPad apps with macOS as a target.
