Passing Data between Views in SwiftUI using @State and @Binding
By the end of this tutorial, you will be able to pass data using @State and @Binding from a primary to a secondary view using a hierarchical navigation in SwiftUI.
When you have multiple views in your SwiftUI App, you often need to share data from one view to the next one. If you've been programming for iOS/iPadOS for a while now, you know that this is something we used to do using a prepareForSegue. However, if you're a newbie, you won't have any problem following this tutorial. There is no need for any previous knowledge of UIKit to pass data between Views using SwiftUI.
This tutorial is the second of a series that explores 4 different solutions for passing data between views:
- Passing Data between Views using a property
- Passing Data between Views using @State and @Binding
- Passing data via the view’s environment
