You don’t need to import the Observation framework as it comes with SwiftUI

And I have a question: If I want to fully adopt the new Observation framework by embracing State, Bindable and Environment wrappers and discard all other property wrappers (like Binding, although I can still use them as they’re not deprecated yet), how do I migrate the following view to the Observation framework in order to be able to do changes on an array of Bindable objects:

“`
struct MyView: View {
@Binding var books: [Book]

var body: some View {
Button(“Add Book”) {
books.append(Book())
}
}
}
“`
I couldn’t find a way to add a book to the array without @Binding property wrapper.

Thanks for the cool article, however, I believe that you don’t need to mark the Library model with @Observable as long as its properties are @Observable.
