Book excerpt: Make beautiful apps with beautiful code: use the elegant and concise Ruby programming language with RubyMotion to write truly native iOS apps with less code while having more fun. You'll learn the essentials of creating great apps, and by the end of this book, you'll have built a fully functional API-driven app. Whether you're a newcomer looking for an alternative to Objective-C or a hardened Rails veteran, RubyMotion allows you to create gorgeous apps with no compromise in performance or developer happiness. Developers interested in native iOS app development have been restricted to the limits of Objective-C and Xcode--until RubyMotion came along. RubyMotion enables you do full iOS development using Ruby. You have access to familiar tools such as Rake and RubyGems and can compile Ruby code into native applications. RubyMotion even comes with a Ruby console useful for live coding and interactive debugging. And since RubyMotion is built on top of the Objective-C runtime, you can use all of Apple's libraries and most third-party code alongside Ruby classes. This book takes you from zero knowledge of iOS development to building an app that displays information about colors using a web service API. You'll work through each topic with a small example app that covers just enough to get you familiar with the techniques you need to get real work done. You'll start with just drawing boxes on the screen, but you'll quickly add animations, a navigation stack, and high-performance table views. You'll peek into less visible components, such as using Ruby metaprogramming to create JSON-based models. You'll use some incredibly useful common Ruby techniques that are only possible in RubyMotion, such as writing automated unit tests with an RSpec-like framework. Using both Apple's existing libraries and fresh, community-driven RubyMotion projects, you'll be well on your way to writing real-world apps. What You Need: A Macintosh running OS X 10.7 or later is required to install RubyMotion. RubyMotion is a commercial product and currently requires a purchased license. Experience with the Ruby language and Ruby tools like RubyGems and Rake are suggested.

Book excerpt: Discover how to use React Native in the real world, from scratch. This book shows you what React Native has to offer, where it came from, and where it’s going. You'll begin with a solid foundation of practical knowledge, and then build on it immediately by constructing three different apps. You'll learn how to use each feature of React Native by working on two full projects and one full game. These aren’t just simple React Native Hello World examples (although you’ll naturally start there!) but are apps that you can, if you so choose, install on your mobile devices and use for real. Throughout this book, you'll gain real-world familiarity with React Native as well as supporting components from Expo, NativeBase, React Navigation and the Redux and Lodash libraries. You'll also build server-side code for a mobile React Native app to talk to using the popular Node.js and Socket.io library, providing you a holistic view of things even beyond React Native. And, you'll see many helpful tips, tricks and gotchas to watch out for along the way! Practical React Native offers practical exercises that will give you a solid grasp of building apps with React Native, allowing you to springboard into creating more advanced apps on your own.Creating a game with React Native will allow you to see a whole other perspective on what React Native can do. What You'll Learn Master the basics of React Native Create a logically structured project Review interface elements, such as widgets, controls, and extensions Build layouts Work with Expo, an open source toolchain Who This book Is For The primary audience is mobile developers and anyone looking to build for multiple mobile platforms and trying to do so with a codebase that is largely the same across all. Readers will need a decent foundation, but not necessarily be experts in, HTML, CSS, and JavaScript, but I'll assume little beyond that.
