SwiftUI is radically different from UIKit. In this short book, we will help you build a mental model of how SwiftUI works. We explain the most important concepts in detail, and follow them up with exercises to get hands-on experience.
SwiftUI is still a very young framework, and as such, we don’t believe it’s appropriate to write a complete reference. Instead, this book focuses on transitioning from the object-oriented style of UIKit to the declarative style of SwiftUI.
Thinking in SwiftUI is targeted at readers who are familiar with Swift and have experience building apps in frameworks like UIKit.
