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.

Chapter 17. Multipeer Augmented Reality

In this chapter, we will see how to create a multi-peer augmented reality app. Until now, we have only made applications that run on a single device and we didn't have to worry about how to connect with an another device and also share data with the other device.

Apple already has a framework to connect with other devices and manage data transfer between the devices. This framework for connecting between devices, called Multipeer Connectivity, has been around since iOS 7. In iOS 12, Apple has extended the functionality of the framework for developers to create Multipeer applications.

In this chapter, we will cover the following topics:

  • Multipeer connectivity framework overview

  • Creating a multipeer session class

  • Creating a UI for the app

  • Setting outlets and adding variables

  • Initializing the view

  • Updating session and tracking

  • Hosting and joining the session

  • Sending and receiving data

  • Initializing a multipeer session

  • Testing the application
