Views don't update with @Published data on subclasses of ObservableObject class for iOS 14

@Published var value: String = ""

Views don't update with @Published data on subclasses of ObservableObject class for iOS 14 while it works for iOS 15. I try following code as workaround:

   var value: String = "" {     willSet { objectWillChange.send() }   }

This works, but does anyone have any better suggestions?
