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.

Authenticating the player's Game Center account

As soon as our app starts, we will check whether the player is already logged in to their Game Center account. If not, we will give them a chance to log in. Later, when we want to submit high scores or achievements, we can use the authentication information we gathered when the app launched, instead of interrupting their gaming session to collect their Game Center information.

Follow these steps to authenticate the player's Game Center account when the app starts:

  1. First, we will turn on Game Center for your project in Xcode. Open the Capabilities tab of your project settings and make sure Game Center is flipped to ON, as shown in the following screenshot:

  2. We will now be working in the GameViewController class, so open GameViewController.swift in Xcode.
  3. Add a new import statement at the top of the file so we can use the GameKit framework:
            import GameKit
  4. In the GameViewController class, add a new function called authenticateLocalPlayer...
