Improve current or new projects with top notch testability and maintainability. Writing tests improves the design of your apps, as it pushes you to have a more modularized design. This in turn improves the maintainability and sustainability of your apps. This book is for iOS developers who already know the basics of iOS and Swift development but want to learn all the testing pro features in iOS. You'll start by reviewing the TDD Cycle and how to implement these concepts on a legacy project or a new one. You'll then walk through TDD step-by-step on a blank project, including setting up test targets, assertions, and expectations. You'll follow that with all levels of testing such as unit tests, integration tests, and end-to-end tests, and also tackle fairly complex, yet badly written legacy code. The book will take you through the journey of modularizing a legacy app using TDD. Throughout this journey, you will be introduced to multiple testing concepts and techniques, like writing tests for network and core data layers. You will write tests to ensure the thread safety of your app. And you'll add a new feature while you are in the middle of refactoring, which is an important skill so you can keep adding features while you are fixing your technical debt. By the end of this book, you will have all the tools needed to become a testing master. What You'll Learn Use mocking and dependency injection to make components more testable Write tests for asynchronous code like network code Add new features to existing legacy apps using TDD Who This Book Is For Experienced iOS developers who care about software quality and meeting customer expectations.

The Cocoa frameworks are some of the most powerful for creating native OS X apps available today. However, for a first-time Mac developer, just firing up Xcode 4 and starting to browse the documentation can be a daunting and frustrating task. The Objective-C class reference documentation alone would fill thousands of printed pages, not to mention all the other tutorials and guides included with Xcode. Where do you start? Which classes are you going to need to use? How do you use Xcode and the rest of the tools? Learn Cocoa for the Mac, Second Edition, completely revised for OS X Mountain Lion and XCode 4, answers these questions and more, helping you find your way through the jungle of classes, tools, and new concepts so that you can get started on the next great OS X app today. Jack Nutting and Peter Clark are your guides through this forest; Jack and Peter have lived here for years, and will show you which boulder to push, which vine to chop, and which stream to float across in order to make it through. You will learn not only how to use the components of this rich framework, but also which of them fit together, and why. Jack Nutting's approach, combining pragmatic problem-solving with a deep respect for the underlying design philosophies contained within Cocoa, stems from years of experience using these frameworks. Peter Clark will show you which parts of your app require you to jump in and code a solution, and which parts are best served by letting Cocoa take you where it wants you to go. The path over what looks like a mountain of components and APIs has never been more thoroughly prepared for your travels. In each chapter, you'll build an app that explores one or more areas of the Cocoa landscape. With Jack's and Peter's guidance, the steep learning curve becomes a pleasurable adventure. There is still much work for the uninitiated, but by the time you're done, you will be well on your way to becoming a Cocoa master.
