So the other thing which came to my mind was similar to what you have
suggested:
a. Declare Displayable protocol with func display()
b. Let each Model implement this protocol
c. Within forEach on children I can just bind and typecast to the protocol
and invoke display method on it
However this looks like an ugly solution to me as Model is now serving 2
responsibilities - i. Handle/ Store data, ii. Handle how the data is
displayed. The 2nd responsibility looks to me like more reasonable for a
controller or presenter class to implement rather than the model class,
hence I want to avoid that path.
