I can't undertand how to use @Binding in combination with ForEach in SwiftUI. When the child view updates the binding, the parent’s state automatically updates too — and SwiftUI re-renders the UI accordingly. SwiftUI’s @State property wrapper lets us modify our view structs freely, which means as our program changes we can update our view properties to match. It is an important core concept for creating an In the world of SwiftUI, data binding is a core concept that facilitates the seamless flow of data between your app’s user interface and its underlying data models. You can manually construct bindings using Binding(get:set:), This tutorial no longer demonstrates current SwiftUI or Xcode practices.
