A quick FizzBuzz I wrote to show pattern matching in Swift’s switch statement.

FizzBuzz.swift

let result = (1 ... 100).map { i -> String in
    switch (i % 3 == 0, i % 5 == 0) {
    case (true, true):
        return "FizzBuzz"
    case (true, false):
        return "Fizz"
    case (false, true):
        return "Buzz"
    default:
        return "\(i)"
    }
}
