Change to @Published var in @EnvironmentObject not reflected immediately

Question

In this specific case, when I try to change an @EnvironmentObject\'s @Published var, I find that the view is not invalidated and updated immediatel

Answer 1

Changing

final class UserData: NSObject, ObservableObject  {

to

final class UserData: ObservableObject  {

does fix the issue in Xcode11 Beta6. SwiftUI does seem to not handle NSObject subclasses implementing ObservableObject correctly (at least it doesn't not call it's internal willSet blocks it seems).
