Jump into the app development world with confidence!
iOS Swift 24-Hour Trainer combines book and video lessons in Apple's Swift programming language to prepare you to build iPhone and iPad apps--and distribute them through the Appstore. First, this approachable text covers the fundamentals of Swift by introducing you to iOS development in this language, and presenting best practices for setting up a development environment and using variables, statements, expressions, operators, functions, and closures. Next, you explore common tasks, such as alert views, table views, and collection views. You then deepen your knowledge of Swift by considering network programming and local data storage. Finally, this engaging resource dives into slightly more advanced concepts, such as tab bars, web views, the accelerometer, camera, photo library, Google maps, and core location.
Swift was designed by Apple to incorporate modern scripting features while offering simpler, cleaner syntax than Objective-C to maintain a minimal and easy to read style. This more expressive code offers numerous key features, such as closures unified with function pointers, tuples and multiple value returns, generics, and functional programming patterns.
Learn how to obtain a device UDID
Test your applications on an actual device, so you can see your work in action
Distribute your applications outside of the App store, allowing you to test your work with real users
Review common reasons why apps are rejected by Apple to strengthen your case when submitting your apps for distribution
iOS Swift 24-Hour Trainer is an essential guide to Apple's Swift programming language for beginning programmers.
