"A view is a (visual) representation of its model. It would ordinarily highlight certain attributes of the model and suppress others. It is thus acting as a presentation filter."

View and model are related, but neither is procedurally dominated by the other. The view is not a subroutine of the model, or vice versa.

They are related entities that communicate in order for the view to function as a representation of its model to the user, and for the model to be manipulated by the user.

To get the details I really recommend the Chatty paper. It is a bit hard to read, but delivers the goods.

Declarative–reactive. Like SwiftUI.
