Getting Started with CombineUIs we used them with. But you might wonder how Combine really works and what goes on under the hood of SwiftUI’s reactive state management system. In this chapter, we’re going to dive into Combine, and you will learn about the underlying principles and why it works so well in combination with SwiftUI.
