![]() SwiftUI lets you build better apps, faster, and with less code. This book is for readers who are comfortable building Swift apps, and want to make the exciting leap into building their app UI with modern, declarative code. SwiftUI by Tutorials is designed to help you learn how to transition from the “old way” of building your app UI with UIKit, to the “new way” of building responsive UI with modern declarative syntax with SwiftUI. And since Combine unifies all of these different mechanisms under a single interface, this opens the door to interesting and powerful ways of composing logic and work in a declarative and universal way.Ĭombine: Asynchronous Programming With Swiftīuild fluid and engaging declarative UI for your apps - using less code - with SwiftUI! What are these asynchronous events, you might ask? Anything that happens over time in your application can be represented by what is known as a Combine Publisher - network requests, user input, notifications, KVO, and much more. You’ll learn everything from the ground up to become a true Combine master.Ĭombine is Apple’s framework to work with asynchronous events in a unified and reactive way that ensures your app is always up to date based on the latest state of its data. And while experience with either of the above is useful, it’s not a prerequisite for this book. The introduction of Combine as a built-in framework in Apple’s ecosystem is promising news to developers who were interested in frameworks such as RxSwift or ReactiveSwift, but didn’t want the overhead of a third-party dependency. With Apple’s introduction of the Combine framework in WWDC 2019, declarative and reactive programming in Swift have become a meaningful aspect of the language and a game-changer in how developers perform and compose pieces of asynchronous work, making it a must-have tool at your disposal. Does it really have to be this hard? Not anymore! ![]() Juggling all of these different mechanisms can be somewhat overwhelming. Writing asynchronous code can be challenging, with a variety of possible interfaces to represent, perform, and consume asynchronous work - delegates, notification center, KVO, closures, etc. ![]() Learn all about declarative asynchronous programming with Swift using the Combine framework!
