Notes from "Protocol-Oriented Programming in Swift"

PS: If you liked this talk or like this concept, let's chat about iOS development at Stitch Fix! #shamelessplug

Protocol-Oriented Programming in Swift

Speaker: David Abrahams. (Tech lead for Swift standard library)

  • "Crusty" is an old-school programmer who doesn't trust IDE's, debuggers, programming fads. He's cynical, grumpy.

  • OOP has been around since the 1970's. It's not actually new.

  • Classes are Awesome

    • Encapsulation
    • Access control
