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.

You’ll then write tests to verify networking endpoints and the ability to mock the returned results, followed by writing tests that run against authentication endpoints. Continue trouble-shooting your apps by understanding common legacy problems, as well as breaking dependencies into modules. And, finally, refactor large classes into smaller, more manageable classes and objects.

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.

Advanced Git

Master 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.

Advanced Git 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.

Take a deep dive into:

How Git actually works: After using Git for a while it’s good to discover the whys behind all of the things. Rebasing: Rebasing and squashing doesn’t have to be scary; it’s quite a useful and advanced way of merging code to support your collaborative workflow. Undoing what you’ve done: Most frustration with Git comes from not being able to undo something that you’ve screwed up. But Git has lots of ways you can go back and recover from a weird merge or commit state. Workflows in Git: Working with Git requires some rules to make sure things go smoothly across development teams. Learn the most common workflows and how to decide which one to use. 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!

Combine: Asynchronous Programming with Swift

Master 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, it is clear that Apple aims to position declarative and reactive programming in Swift as a long-term investment 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 could be useful, it is 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.

Combine is also tightly integrated throughout Apple’s SDKs. For example, the UI framework SwiftUI uses Combine to ensure your app’s views stay up to date, which makes Combine a must-have for your skillset.

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!

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.
