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.
