By this statement I mean that they tell us that with POP we should begin our design with the protocol rather than with the superclass as we did with OOP however the protocol design tends to mirror the superclass design of OOP. They also tell us that we should use extensions to add common functionality to types that conform to a protocol as we did with superclasses in OOP. While protocols and protocol extensions are arguably two of the most important concepts of POP these tutorials seem to be missing some other very important concepts. </div><div style="margin:0px;line-height:normal;color:rgb(69,69,69);min-height:14px" class=""><br class=""></div><div style="margin:0px;line-height:normal;color:rgb(69,69,69)" class="">In this post I would like to compare Protocol-Oriented design to Object-Oriented design to highlight some of the conceptual differences.
