One of the strengths of Swift is its extensibility, that means that you can build up the language from small components that can be composed together easily. Functions such as sort can be both simple to use – but very powerful when needed. This talk will show how functions that take other functions, and treating functions as data, can be used to improve readability, as well as replicate the dynamic functionality of selectors in Objective-C.
