It seems as if everyone is writing applications for Apple's iPhone and iPad, but how do they all do it? It's best to learn Objective-C, the native language of both the iOS and Mac OS X, but where to begin? Right here, even if you've never programmed before

Objective-C for Absolute Beginners will teach you how to write software for your Mac, iPhone, or iPad using Objective-C, an elegant and powerful language with a rich set of developer tools. Using a hands-on approach, you'll learn to think in programming terms, how to use Objective-C to build program logic, and how to write your own applications and apps.

With over 50 collective years in software development and based on an approach pioneered at Carnegie Mellon University, the authors have developed a remarkably effective approach to learning Objective-C. Since the introduction of Apple's iPhone, the authors have taught hundreds of absolute beginners how to develop Mac, iPhone, and iPad apps, including many that became popular apps in the iTunes App Store. What you'll learn The fundamentals of computer programming: how to understand variables, design data structures, and work with file systems The logic of object-oriented programming: how to use Classes, Objects, and Methods The flexibility of Apple's developer tools: how to install Xcode and write programs in Objective-C The power of Cocoa and Cocoa touch: how to make Mac OS X applications or iOS apps that do cool stuff Who this book is for

Design is a challenge for most developers. Without a background or training in user interface skills, it's hard to navigate what choices make the best sense for the end user. This book shows you how to migrate from Storyboards to SwiftUI to design dynamic and engaging UIs for iOS apps. SwiftUI is new in iOS 13 but you may want to support past versions as well. To satisfy this, you'll start by reviewing nib/xib files and Storyboards and then move into SwiftUI and explore how to design apps in both UI toolkits. Gaining a firm base in technologies old and new will allow you to future proof your UI during this period of transition. Developers generally want to stay in code, but UI development tends to be a visual effort. This book takes a very structured and code-like approach to UI design to take the fear away. You'll grasp Storyboards and Auto-Layout/Constraints, while also learning to move past them with the easier options in SwiftUI. A clear understanding of both technologies is key to keeping your most functional coding and also making things look right. With UI Design for iOS App Development, you'll learn SwiftUI easily and get back into your code quickly. What You'll Learn Build iOS app UIs both in current and new paradigms Work with Storyboards and Auto-Layout/Constraints Design UIs in a coder friendly way Who This Book Is For iOS developers building a strong foundation in UI design to fill in the gaps from their training. For veteran developers, it's vital to be able to match your coding skills with equal UI/UX abilities.
