Swift Combine: Unknown attribute 'ObservedObject' error

Question

I have the following implementation:

final class Article: NSManagedObject {
    @NSManaged var title: String!
    @NSManaged var summary: String!
}

class someOtherClass {
    @ObservedObject var article: Article?
}

But I'm getting this error:

Unknown attribute 'ObservedObject'

My question is how can I fix this error? or any of you knows a work around.

It's unclear what you are going to accomplish. And never declare `@NSManaged` properties as IUO. — vadian, Oct 19 '21 at 20:15
@vadian I want to observe and react with any changes in my core data stack — user2924482, Oct 19 '21 at 20:16

If you want to access a class in another class you have to create a reference of it. You would only use observedobject, environmentobject, etc. in your view.
