Copy and paste the swift code below into a playground to experiment.

This is a very close emulation of Functor and Monad typeclasses in swift. However, it is very fragile (i.e. easy to crash the compiler).

For example, instance methods of fmap will run fine, but attempting to use a globally defined fmap that acts on Functor types will cause a crash. Similarly for bind. Unfortunately this means we cannot define the nice infix operator versions of these functions.

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

val square : Int => Int = x => x * x

Purpose of this list is to gather a source of information on how many people are working on iOS application.
I often wonder how many people are behind Facebook's app or Twitter's. If you're as curious as me, please share and please add apps 😉.
