The goal of this book is to teach the skills necessary to create iOS applications using the iOS 8 SDK, Xcode 6 and the Swift programming language.
How you make use of this book will depend to a large extent on whether you are new to iOS development, or have worked with iOS 7 and need to get up to speed on the features of iOS 8 and the Swift programming language. Rest assured, however, that the book is intended to address both category of reader.
For New iOS Developers
If you are entirely new to iOS development then the entire contents of the book will be relevant to you.
Beginning with the basics, this book provides an outline of the steps necessary to set up an iOS development environment. An introduction to the architecture of iOS 8 and programming in Swift is provided, followed by an in-depth look at the design of iOS applications and user interfaces. More advanced topics such as file handling, database management, in-app purchases, graphics drawing and animation are also covered, as are touch screen handling, gesture recognition, multitasking, iAds integration, location management, local notifications, camera access and video and audio playback support. Other features are also covered including Auto Layout, Twitter and Facebook integration, App Store hosted in-app purchase content, collection views, Sprite Kit-based game development, local map search and user interface animation using UIKit dynamics.
The key new features of the iOS 8 SDK and Xcode 6 are also covered, including Swift playgrounds, universal user interface design using size classes, app extensions, Interface Builder Live Views, embedded frameworks, CloudKit data storage and TouchID authentication.
The aim of this book, therefore, is to teach you the skills necessary to build your own apps for iOS 8. Assuming you are ready to download the iOS 8 SDK and Xcode, have an Intel-based Mac and ideas for some apps to develop, you are ready to get started. <google>BUY_IOS8</google>
