Overview of this book

The iOS development environment has significantly matured, and with Apple users spending more money in the App Store, there are plenty of development opportunities for professional iOS developers. However, the journey to mastering iOS development and the new features of iOS 12 is not straightforward. This book will help you make that transition smoothly and easily. With the help of Swift 4.2, you’ll not only learn how to program for iOS 12, but also how to write efficient, readable, and maintainable Swift code that maintains industry best practices. Mastering iOS 12 Programming will help you build real-world applications and reflect the real-world development flow. You will also find a mix of thorough background information and practical examples, teaching you how to start implementing your newly gained knowledge. By the end of this book, you will have got to grips with building iOS applications that harness advanced techniques and make best use of the latest and greatest features available in iOS 12.

Understanding and controlling animation progress


One of the best features of UIViewPropertyAnimator is that you can use it to create animations that can be interrupted, reversed, or interacted with. Many of the animations you see in iOS are interactive animations. For instance, swiping on a page to go back to the previous page is an interactive transition. Swiping between pages on the home screen, opening the control center, or pulling down the notification center are all examples of animations that you manipulate by interacting with them.

While the concept of interactive animations might sound complicated, UIViewPropertyAnimator makes it quite simple to implement them. As an example, you'll see how to implement a drawer on the contact detail page in the Hello-Contacts app. First, you'll prepare the view, so the drawer is partially visible in the app. Once the view is all set up, you will write the code to perform an interactive show-and-hide animation for the drawer.
