Swift Game Development - Third Edition

By: Siddharth Shekar, Stephen Haney

Overview of this book

Swift is the perfect choice for game development. Developers are intrigued by Swift and want to make use of new features to develop their best games yet. Packed with best practices and easy-to-use examples, this book leads you step by step through the development of your first Swift game. The book starts by introducing Swift's best features – including its new ones for game development. Using SpriteKit, you will learn how to animate sprites and textures. Along the way, you will master physics, animations, and collision effects and how to build the UI aspects of a game. You will then work on creating a 3D game using the SceneKit framework. Further, we will look at how to add monetization and integrate Game Center. With iOS 12, we see the introduction of ARKit 2.0. This new version allows us to integrate shared experiences such as multiplayer augmented reality and persistent AR that is tied to a specific location so that the same information can be replicated on all connected devices. In the next section, we will dive into creating Augmented Reality games using SpriteKit and SceneKit. Then, finally, we will see how to create a Multipeer AR project to connect two devices, and send and receive data back and forth between those devices in real time. By the end of this book, you will be able to create your own iOS games using Swift and publish them on the iOS App Store.

Designing levels with the SpriteKit scene editor


The Scene editor is a valuable addition to SpriteKit. Previously, developers would be forced to hard-code positional values or rely on third-party tools or custom solutions for level design. Now, we can lay out our levels directly within Xcode by dragging and dropping sprites. We can create nodes, attach physics bodies and constraints, create physics fields, and edit properties directly from the interface.

Here is a simple example scene you might build by simply clicking and dragging:

In this example, I simply dragged and positioned sprites in the scene. If you are making an unsophisticated game, you can start in the scene editor rather than creating custom classes. By editing physics bodies in the editor, you can even create entire physics-based games in the editor, adding only a few lines of code for the controls.

Complex games require custom logic and texture animation for every object, so we will implement a system in our penguin game that...
