Design and develop sophisticated 2D games that are as much fun to make as they are to play. From particle effects and pathfinding to social integration and monetization, this complete tour of Apple’s powerful suite of game technologies covers it all. Familiar with Swift but new to game development? No problem. Start with the basics and then layer in the complexity as you work your way through three exciting – and fully playable – games. In the end, you’ll know everything you need to go off and create your own video game masterpiece for any Apple platform.

Discover the power of Apple Game Frameworks, Xcode, and Swift by building three exciting games: Gloop Drop – a new twist on a classic arcade game, Val’s Revenge – a roguelike dungeon crawler, and Hog – a social player vs. player mobile dice game. With Apple Game Frameworks, you can create high-performance, power-efficient games that work across all Apple platforms, including iOS, macOS, tvOS, and watchOS.

In this book, you’ll discover how to…

Design and develop rich 2D gaming experiences using Apple’s built-in game frameworks. Harness the power of SpriteKit using Xcode and Swift to create engaging player experiences. Use the visual Scene Editor to build complete scenes. Unleash the power of the Particle Editor to create amazing effects. Use GameplayKit to add advanced features to your games like pathfinding, artificial intelligence, and complex rule systems. Build larger, more complex worlds with tile maps and Xcode’s visual Tile Map editor. Bring people together using GameKit and Game Center, Apple’s social gaming network. Increase revenue with third-party banner ads and rewarded ads using Google AdMob (TM). Monetize your games with StoreKit and in-app purchases.

So, grab your gear and get your game on – it’s time to level up your skills.

Fearlessly change the design of your iOS code with solid unit tests. Use Xcode’s built-in test framework XCTest and Swift to get rapid feedback on all your code – including legacy code. Learn the tricks and techniques of testing all iOS code, especially view controllers (UIViewControllers), which are critical to iOS apps. Learn to isolate and replace dependencies in legacy code written without tests. Practice safe refactoring that makes these tests possible, and watch all your changes get verified quickly and automatically. Make even the boldest code changes with complete confidence.

Manual code and UI testing get slower the deeper your navigation hierarchy goes. It can take several taps just to reach a particular screen, never mind the actual workflow tests. Automatic unit testing offers such rapid feedback that it can change the rules of development. Bring testing to iOS development, even for legacy code. Use XCTest to write unit tests in Swift for all your code.

iOS developers typically reserve unit tests for their model classes alone. But that approach skips most of the code common to iOS apps, especially with UIViewControllers. Learn how to unit test these view controllers to expand your unit testing possibilities. Since good unit tests form the bedrock for safe refactoring, you’re empowered to make bold changes. Learn how to avoid the most common mistakes Swift programmers make with the XCTest framework. Use code coverage to find holes in your test suites. Learn how to identify hard dependencies.

Reshape the design of your code quickly, with less risk and less fear.
