Types

A type is a collection of possible values. An integer can have values 0, 1, 2, 3, etc.; a boolean can have values true and false. We can imagine any type we like: for example, a HighFive type that allows the values "hi" or 5, but nothing else. It's not a string and it's not an integer; it's its own, separate type.

Statically typed languages constrain variables' types: the programming language might know, for example, that x is an Integer. In that case, the programmer isn't allowed to say x = true; that would be an invalid program. The compiler will refuse to compile it, so we can't even run it.

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
