Overview of this book

Swift is the perfect choice for game development. Developers are intrigued by Swift 3.0 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. This book starts by introducing SpriteKit and Swift's new features that can be used for game development. After setting up your first Swift project, you will build your first custom class, learn how to draw and animate your game, and add physics simulations. Then, you will add the player character, NPCs, and powerups. To make your game more fun and engaging, you will learn how to set up scenes and backgrounds, build fun menus, and integrate with Apple Game Center to add leaderboards and achievements. You will then make your game stand out by adding animations when game objects collide, and incorporate proven techniques such as the advanced particle system and graphics. Finally, you will explore the various options available to start down the path towards monetization and publish your finished games to the App Store. By the end of this book, you will be able to create your own iOS games using Swift and SpriteKit.

Preface

Cleaning up


I hope that you have absorbed some Swift syntax and gained an overview of Swift and SpriteKit. It is time to make room for our own game; let's clear all of that demo code out! We want to keep a little bit of the boilerplate, but we can delete most of what is inside the functions. To be clear, I do not expect you to understand this code yet. This is simply a necessary step towards the start of our journey.

Firstly, we will remove the Hello, World text from the demo. Open the file GameScene.sks from the project navigator in Xcode. You will see a gray layout view with Hello, World written in the middle. Simply click anywhere on the Hello, World text and press your delete key to remove it. Make sure you save your file before moving on.

Secondly, please replace all of the code from your GameScene.swift with the following code:

import SpriteKit 
 
class GameScene: SKScene { 
    override func didMove(to view: SKView) { 
    } 
} 

Once your GameScene.swift looks like the preceding code, you are ready to move on to Chapter 2, Sprites, Camera, Actions! The real fun begins now!
