My mistake - indeed ObservableObject is part of Combine, it's only ObservedObject that's part of SwiftUI.

However, this is still two ways to use Combine to observe a class with multiple properties. Either way you need @Published on the properties. But you can then either

(a) use @ObservableObject to get notified when any property on the object will change, then re-read all the properties in a callback; or

(b) subscribe directly to the property Publishers.

@comex I'm very curious what you're doing with said properties, while what you're describing is of course true, neither sounds like a very common pattern

@kylebshr Well, the first one is, I believe, effectively what happens when you use ObservedObject in a SwiftUI View.

But it's deprecated, I know.
