To disable textfield for edit mode on iOS13

[LukaszDziwosz]

As we can't use .onChange on iOS 13 here is solution with .onReceive: .

onReceive(Just(editMode?.wrappedValue)) { newValue in
                        if (newValue != nil) && (newValue!.isEditing) {
                            disableTextField = false // Edit button tapped
                            } else {
                            disableTextField = true // Done button tapped
                            }
                    }

You just have to import Combine, works the same
