This book aims to teach the skills necessary to create i OS apps using the i OS 17 SDK, UIKit, Xcode 15 Storyboards, and the Swift programming language.

Beginning with the basics, this book outlines the steps necessary to set up an i OS development environment. Next, an introduction to the architecture of i OS 17 and programming in Swift is provided, followed by an in-depth look at the design of i OS apps and user interfaces. More advanced topics such as file handling, database management, graphics drawing, and animation are also covered, as are touch screen handling, gesture recognition, multitasking, location management, local notifications, camera access, and video playback support. Other features include Auto Layout, local map search, user interface animation using UIKit dynamics, i Message app development, and biometric authentication.

Additional features of i OS development using Xcode are also covered, including Swift playgrounds, universal user interface design using size classes, app extensions, Interface Builder Live Views, embedded frameworks, collection and stack layouts, Cloud Kit data storage, and the document browser.

Other features of i OS 17 and Xcode 15 are also covered in detail, including i OS machine learning features.

The aim of this book, therefore, is to teach you the skills necessary to build your own apps for i OS 17. Assuming you are ready to download the i OS 17 SDK and Xcode 15, have a Mac, and some ideas for some apps to develop, you are ready to get started.
