The zip() function joins two sequences

Available from Swift 1.2

If you have two sequences that you'd like to join together, the zip() function will do just that and return an array of tuples. For example:

let names = ["Sophie", "Charlotte", "John"]
let scores = [90, 92, 95]
let zipped = zip(names, scores)

That will output an array of the tuples ("Sophie", 90), ("Charlotte", 92), and ("John", 95).
