Functional programing at its finest

Swift has been around for a few years and many developers are now accustomed with the basic operations of functional programing, such as
Still, most of the more advanced concepts have yet to reach a large audience, which is a real shame given the power they can bring to a code base.
This talks aims at introducing three of those advanced techniques :
flatMap()operator and its many fields of application, such as building asynchronous streams, keeping a log of all the operations applied on a value or chaining together failable computations. (Yep, we're talking about Monads here)
Partial application of functions (also known as currying), which enables developers to manipulate the signature of a function, allowing them to easily write code that bridges different frameworks together or specialize existing functions in order to tailor them to their exact needs
Property-based testing, a sort of fuzzing-on-steroids approach in which developers use functions to write properties that describe the behavior of their program, and feed those properties to a testing engine that will then try to find counter-example for which the properties do not hold
