Use test-driven approach to develop highly-functional iOS apps with Swift 4 and Xcode 9 About This Book A practical guide to writing effective, organized, and clean code that works well Learn test-driven principles to help you build better-designed apps with fewer bugs A comprehensive overview of the techniques available for TDD in Swift Who This Book Is For To get the most out of this book, you will need some prior experience with Swift application development. You may have already heard about Test-Driven Development (TDD) but you don't need any prior experience of applying it to Swift applications. What You Will Learn Implement TDD in Swift application development Find bugs before you enter code using the TDD approach Use TDD to build models, view controllers, and views Test network code with asynchronous tests and stubs Write code that is a joy to read and maintain Develop functional tests to ensure the app works as planned In Detail Test-driven development (TDD) is a proven way to find software bugs early. Writing tests before you code improves the structure and maintainability of your apps. Using TDD, in combination with Swift 4's improved syntax, means there is no longer any excuse for writing bad code. This book will help you understand the process of TDD and how to apply it to your apps written in Swift. Through practical, real-world examples, you'll learn how to implement TDD in context. You will begin with an overview of the TDD workflow and then delve into unit-testing concepts and code cycles. You will also plan and structure your test-driven iOS app, and write tests to drive the development of view controllers and helper classes. Next, you'll learn how to write tests for network code and explore how the test-driven approach—in combination with stubs—helps you write network code even before the backend component is finished. Finally, the book will guide you through the next steps to becoming a testing expert by discussing integration tests, Behavior Driven Development (BDD), open source testing frameworks, and UI Tests (introduced in Xcode 9). Style and approach Using a step-by-step approach, you will develop an entire iOS app using TDD. During the course of the book, you will explore different strategies for writing tests for models, View Controllers, and networking code.

As iOS apps become increasingly complex and business-critical, iOS developers must ensure consistently superior code quality. This means adopting best practices for creating and testing iOS apps. Test-Driven Development (TDD) is one of the most powerful of these best practices. Test-Driven iOS Development is the first book 100% focused on helping you successfully implement TDD and unit testing in an iOS environment. Long-time iOS/Mac developer Graham Lee helps you rapidly integrate TDD into your existing processes using Apple’s Xcode 4 and the OCUnit unit testing framework. He guides you through constructing an entire Objective-C iOS app in a test-driven manner, from initial specification to functional product. Lee also introduces powerful patterns for applying TDD in iOS development, and previews powerful automated testing capabilities that will soon arrive on the iOS platform. Coverage includes Understanding the purpose, benefits, and costs of unit testing in iOS environments Mastering the principles of TDD, and applying them in areas from app design to refactoring Writing usable, readable, and repeatable iOS unit tests Using OCUnit to set up your Xcode project for TDD Using domain analysis to identify the classes and interactions your app needs, and designing it accordingly Considering third-party tools for iOS unit testing Building networking code in a test-driven manner Automating testing of view controller code that interacts with users Designing to interfaces, not implementations Testing concurrent code that typically runs in the background Applying TDD to existing apps Preparing for Behavior Driven Development (BDD) The only iOS-specific guide to TDD and unit testing, Test-Driven iOS Development covers both essential concepts and practical implementation.

Put into motion practical examples to master Test-Driven Development (TDD) and acceptance testing in Swift. This book uses a pragmatic approach to writing well-tested code and provides techniques that can be used to retrofit tests to legacy code bases. You'll be introduced to basic principles of TDD, such as Test First, Red-Green-Refactor, Remove Duplicate code, Dependency Injection, and Single Responsibility. Approaches covered include TDD, behavior-driven development (BDD), UI, and acceptance testing with common standard/open source frameworks. iOS Code Testing offers helpful instruction to teach iOS developers to retrospectively fit tests to legacy code, refactor legacy code so as to make the code more testable, install and configure a popular Swift BDD framework, practice BDD with Xcode, and create automated UI tests with Xcode. Additionally, many projects have legacy code bases. Legacy code is often seen as a blocker when it comes to implementing any kind of testing. What You Will Learn Fit test to legacy code retrospectively Install and configure popular Swift BDD frameworks Practice BDD with Xcode Who This Book Is For Software practitioners, such as Swift developers and mobile app testers.

Make your Swift apps agile and sound with this short step by step guide. You'll learn about unit testing, mocking and continuous integration and how to get these key ingredients running in your Swift projects. This book also looks at how to write your Swift apps using test driven development (TDD). Agile practices have made major inroads in iOS development, however it’s very unusual to see something as basic as unit testing on a Swift application. Done correctly, Agile development results in a significant increase in development efficiency and a reduction in the number of defects. Apple has released unit testing and code coverage frameworks for Swift development in XCode. Up until now getting unit testing up and running in Swift was not for the faint-hearted. Thankfully now, there is no excuse other than a lack of information on where to get started. iOS developers are faced with their own set of problems such as tightly coupled code, fragmentation, immature testing tools all of which can be solved using existing Agile tools and techniques. Swift Programming Using Agile Tools and Techniques is your solution to handling these tasks. What You Will Learn Write unit tests in Swift Write an application using test driven development Examine GUI testing, refactoring, and mocking frameworks Set up and configure a continuous integration server Measure code coverage Who This Book Is For Swift developers and would be mobile app testers will benefit from the guidance in this book.

This book and online video package is a self-paced guide to Swift programming. Easy-to-follow lessons, reinforced by step-by-step instructions, screencasts, and supplemental exercises, allow readers of all learning styles to master Swift programming quickly and painlessly. The book starts at the very beginning, assuming you have little or no programming experience. The book is divided into lessons that teach a specific concept or technique, and then invites you to "Try It", by performing a programming exercise to solidify the lesson's ideas. The Try It has several subsections: Goals describes the exercise so you know what should happen. Hints give pointers about possible confusing aspects of the problem if they are needed. Step-by-Step provides a numbered series of steps that show how to solve the problem. The book covers the fundamentals of using Swift to create iPhone and iPad apps. The first section introduces you to iOS development with Swift. You will learn how to set up a development environment, and learn fundamental Swift programming concepts like variables, statements, expressions, operators, functions, and closures. Next, you will learn how to accomplish common tasks with Swift, like alert views, table views, and collection views. More lessons tackle network programming and local data storage. Topic introduced here will be XML parsing, JSON parsing, Core Data, and consuming web services with NSURLConnection. You will also learn slightly more advanced concepts, including Tab bars, Web views, the Accelerometer, Camera and photo library, Google maps, and Core Location. Finally, you will learn how to: obtain a device UDID. test your applications on an actual device. distribute your applications outside the Appstore to clients for testing. distribute your app from the Appstore and also lists common reasons why applications are rejected.
