Data Flow in a SwiftUI App

In this lesson I want to review with you how data both plays a part in your view and also how it flows through your app across multiple views.

We’ll start with the simplest scenario and work our way to more complex scenarios.

You’ll see examples using state properties, bindings, observable objects, environment objects as well as other data related SwiftUI keywords such as @Published, @ObservedObject and more.

By the end, you’ll know how to pass data around in your SwiftUI app!
