7. Swift is just not a syntax migration from Objective-C…
8. Swift is not objective-c styled language…
9. C ~> C++ Objective-C ~> Swift { imperative } { object oriented } { object oriented } { protocol oriented }
10. Entity (class, struct - UI or Model) vs Behaviour (protocol)
11. Entity is collection of behaviours…

25. thinking in protocol..
26. protocol ->
27. protocol -> protocol extension ->
28. protocol -> protocol extension -> protocol 
 constrained extension ->
29. playground demos..
30. protocol is not a silver bullet.. http://chris.eidhof.nl/post/protocol-oriented-programming/
31. ..computed variables, extensions, values types, immutability, functional programming, generics, enums, associative types/ values..
