Associated Types - Advanced Swift - Protocol Oriented Programming

Have used too complex example for a simple solutions

Excellent explanation, keep up the good work

It's not too hard of an example... But Thanks for the excellent explanation-

Why? Why do we need such rocket science example for explaining associated type? stop making things complex, make it simple.

The problem with this tutorial is that the issue of associatedTypes gets lost in the details of a fairly complex example. Since this isn't a math class perhaps a simpler example might help drive home the lesson better?
