Using tuples as lightweight types in Swift

One really interesting feature of Swift is the ability to create lightweight value containers using tuples. The concept is quite simple - tuples let you easily group together any number of objects or values without having to create a new type. But even though it's a simple concept, it opens up some really cool opportunities, both in terms of API design and when structuring code. This week, let's take a look at how we can use tuples in our code, and some of the techniques that they enable us to use.
