Whether you are an expert Objective-C programmer or are new to this platform, you'll quickly grasp the code of real world apps, and discover how to use Swift effectively. Prior experience in development for Apple devices would be helpful, but is not mandatory. What You Will Learn Create a server in Swift to deliver JSON data to an iOS app Take advantage of Cocoapods to use third-party libraries Use a clean and effective architecture to decrease complexity and speed up development Take advantage of the most useful parts of the iOS SDK Build games with SpriteKit and SceneKit Develop an app running on the cloud to act as an API server for your client's apps In Detail Swift is no longer the unripe language it was when launched by Apple at WWDC14, now it's a powerful and ready-for-production programming language that has empowered most new released apps. Swift is a user-friendly language with a smooth learning curve; it is safe, robust, and really flexible. Swift 2 is more powerful than ever; it introduces new ways to solve old problems, more robust error handling, and a new programming paradigm that favours composition over inheritance. Swift 2 by Example is a fast-paced, practical guide to help you learn how to develop iOS apps using Swift. Through the development of seven different iOS apps and one server app, you'll find out how to use either the right feature of the language or the right tool to solve a given problem. We begin by introducing you to the latest features of Swift 2, further kick-starting your app development journey by building a guessing game app, followed by a memory game. It doesn't end there, with a few more apps in store for you: a to-do list, a beautiful weather app, two games: Flappy Swift and Cube Runner, and finally an ecommerce app to top everything off. By the end of the book, you'll be able to build well-designed apps, effectively use AutoLayout, develop videogames, and build server apps. Style and approach These easy-to-follow tutorials show you how to build real-world apps. The difficulty and complexity level increases chapter by chapter. Each chapter is dedicated to build a new app, beginning from a basic and unstyled app through to a full 3D game. The last two chapters show you how to build a complete client-server ecommerce app right from scratch.

When Apple announced Swift at the WWDC, the iOS developer community became excited about the opportunities to improve the way in which they build iOS apps. Swift is a user-friendly language with a smooth learning curve; it is safe, robust, and flexible, and it introduces new ways to solve old problems. Swift by Example is a fast-paced, practical guide that shows you how to develop iOS apps using Swift. Through the development of six different apps, you'll learn how to use either the right feature of the language or the right tool to solve a given problem. By the end of the book you will be able to build well-designed apps, effectively use AutoLayout, and develop a video game.

Build robust and scalable iOS and Mac OS X game applications About This Book Learn to use and implement the 23 Gang of Four design patterns using Swift 2 Design and architect your code for Swift application development Understand the role, generic UML design, and participants in the class diagram of the pattern by implementing them in a step-by-step approach Who This Book Is For This book is intended for competent Swift developers who want to apply enduring design patterns with Swift to structure and scale their application code. What You Will Learn Choose the appropriate pattern depending on the problem to be solved Understand the generic class diagram of each of the 23 GoF patterns and how each object participates in the pattern Use Swift to implement these patterns even though the language doesn't provide all of the object-oriented programming concepts such as abstract class, interface, and so on Architect your software to avoid the overuse of memory, time spent on calculations, or high network traffic Find the best way to organize your code to make it more secure from the outside world Prepare your code to make it more flexible when the consumer changes or the third-party component hidden code changes Structure your code to change the algorithm to apply at runtime Deliver Flyweight responsibility to your objects In Detail Swift is a multi-paradigm language. It has expressive features familiar to those used to work with modern functional languages, while also keeping the object-oriented features of Objective-C. It remains compatible with Apple's legacy codes and frameworks. A design pattern systematically names, motivates, and explains a general design that addresses a recurring design problem in object-oriented systems. It describes the problem, the solution, when to apply the solution, and its consequences. It also gives implementation hints and examples. Knowledge about design patterns is also one of the best ways to make you different compared to other low-level developers. This book shows you how to use Swift 2 to learn about 23 Gang of Four (GoF) design patterns, and is organized into three categories. The book will present you the five creational patterns, followed by the seven structural patterns, and finishing with the 11 behavioral patterns as defined by the GoF. Each chapter will introduce the pattern by defining its role, which common problems the pattern should be used for, its generic UML representation, how each objects presented in the class diagram participate in the pattern, and what the role of each of these objects is. The book then presents you with a concrete case as an illustration that will be used to implement the pattern using Swift. Style and approach A step-by-step tutorial completed with screenshots and code highlights wherever necessary. Each chapter discusses one or more patterns with its definitions and a simple-to-follow illustration case using a playground or XCText project to implement it with Swift.

Dive into Combine! Writing asynchronous code can be challenging, with a variety of possible interfaces to represent, perform, and consume asynchronous work - delegates, notification center, KVO, closures, etc. Juggling all of these different mechanisms can be somewhat overwhelming. Does it have to be this hard? Not anymore! In this book, you'll learn about Combine - Apple's framework to work with asynchronous events in a unified and reactive way that ensures your app is always up to date based on the latest state of its data. Who This Book Is For This book is for intermediate iOS developers who already know the basics of iOS and Swift development but are interested in learning declarative/reactive programming and take their app and state management to the next level. You'll also find this book interesting if you're interested in SwiftUI - as many of the reactive capabilities keeping your SwiftUI views up-to-date are built on top of Combine. Topics Covered in Combine: Asynchronous Programming with Swift What & Why: Learn what is Combine and reactive programming and the problems they solve, and how you can unify all of your asynchronous piece of work. Operators: Learn how to compose, transform, filter and otherwise manipulate different pieces of asynchronous work using operators. In Practice: You'll gain knowledge on various topics and techniques you'll leverage when writing your own real-life apps, as well as practice these techniques with actual hands-on apps and projects. SwiftUI: You'll learn about how Combine is deeply rooted within SwiftUI and provides it with the ability to reactively update its views based on the state of your app. Advanced Combine: Once you've got a handle on the basics, you'll dive into advanced Combine topics such as Error Handling, Schedulers, and Custom Publishers. By the end of this book, you'll be a pro in building full-fledged applications using Combine's various abilities.
