As you can see, environment objects are a really nice SwiftUI feature, for keeping the code that connects views as simple as possible.

  @EnvironmentObject var library: Library
  @Environment

  var body: some View {
@Environment(\.dismiss)
@Environment(\.dimiss) var dismiss
            library.addNewBook(book, image: image)
            dismiss()
          }
            presentationMode.wrappedValue.dismiss()
          }
          .disabled(

          )
        }
          .disabled(
            [book.title, book.author]
          )
[book.title, book.author].contains(where: \.isEmpty)
