This week, let’s dive deep into the world of pattern matching in Swift — to take a look at how we can construct completely custom patterns, and some of the interesting techniques that we can unlock by doing so.

One really elegant aspect of Swift’s design is how it manages to hide much of its power behind much simpler programming constructs. Pattern matching is one source of that power, especially considering how it’s integrated into many different aspects of the language.

While switch statements are hardly something that was invented as part of Swift, they are made a lot more powerful when combined with Swift's type system. This week - let's go further beyond switching on single enum values and take a look at more of the powerful capabilities that switch statements offer in Swift.
