So you have a great game idea for iPhone or iPad, but Objective-C just seems a bit daunting. What are your alternatives? The App Store is very picky about languages, but there is hope: Lua is a versatile, lightweight, fast, and easy to learn language that you can use to build your iOS games and get them accepted into the App Store. Learn Lua for iOS Game Development walks you through the Lua basics, then shows you how to create games using the top Lua frameworks like Corona SDK, Gideros, Moai, and even how to create games on the iPad (not just for the iPad) with Codea. You aren't tied to Xcode and Objective-C -- you can create all sorts of amazing games with Lua. But if you already have an existing iOS game, you'll also learn how to integrate Lua to extend the game. If you're an aspiring or current iOS developer, you need to know Lua, and Learn Lua for iOS Game Development will give you just what you need to do that.

Dive into the world of developing for all of Apple platforms with SwiftUI, Apple’s new framework that makes writing applications faster and easier with fewer lines of code. This book teaches the basics of SwiftUI to help you write amazing native applications using XCode.For developers already familiar with ReactNative, this book reviews the declarative, state-based DSL that manages the UI and updates it automatically will feel just like what they’re used to. You'll see how SwiftUI reduces the number of lines of code required to achieve the same effects by over 60% and provides a much better experience. Like the announcement of Swift in 2014, SwiftUI is expected to fundamentally change the way developing programmers approach coding iPhone and iPad applications. This book examines how SwiftUI lowers the entry barrier for developers to write amazing cross-platform applications for iOS and iPadOS as well as WatchOS, Mac OS, and TVOS. What You'll LearnWrite code in the new SwiftUI syntaxCombine views to arrange them for an applicationAdd gestures and controls to an applicationWho This Book Is ForAnyone who wants to learn to develop apps for the Mac, iPhone, iPad, and Apple Watch using the Swift programming language. No previous programming experience is necessary.

Learn how to effectively utilize the Bash shell in your programming. This refreshed and expanded third edition has been updated to Bash 5.2, and many scripts have been rewritten to make them more idiomatically Bash, taking better advantage of features specific to Bash. It is easy to read, understand, and will teach you how to get to grips with Bash programming without drowning you in pages and pages of syntax.Using this book you will be able to use the shell efficiently, make scripts run faster using expansion and external commands, and understand how to overcome many common mistakes that cause scripts to fail. This book is perfect for all beginning Linux and Unix system administrators who want to be in full control of their systems, and really get to grips with Bash programming.The Bash shell is a complete programming language, not merely a glue to combine external Linux commands. By taking full advantage of Shell internals, Shell programs can perform as snappily as utilities written in C or other compiled languages. And you will see how, without assuming UNIX lore, you can write professional Bash programs through standard programming techniques.What You'll Learn Use the Bash shell to write utilities and accomplish most programming tasksReplace many external commands with shell parameter expansion making scripts very fastAvoid many common mistakes that cause scripts to failSee how Bash’s read line and history libraries can save typing when getting user inputBuild shell scripts that get information from the WebWho This Book Is ForDevelopers, programmers, and open source enthusiasts who want to write scripts using Bash on multiple platforms
