Swift Internals

This book is designed for Swift developers who want to go beyond writing working code and understand how the language truly works under the hood.

It explains the mechanics of Swift’s type system, compiler behavior, memory model, and performance characteristics. Readers will also learn advanced topics like unsafe memory operations, metaprogramming, modular architecture, and linking strategies.

The goal is to help developers reason about Swift at the language, compiler, and system levels. It is ideal for Swift engineers who want to write faster, safer, and more scalable apps.

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!

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.
