The following will get you an array from the return value of Zip2: var myZip = Zip2([1, 2, 3], ["a", "b", "c"]).generate() var myZipArray: Array<(Int, String)> = [] while let elem = { myZipArray += elem } println(myZipArray) // [(1, a), (2, b), (3, c)] -- UPDATE: EVEN BETTER! -- let myZip = Zip2([1, 2, 3], ["a", "b", "c"]) let myZipArray = Array(myZip) println(myZipArray) // [(1, a), (2, b), (3, c)] -- now for fun -- I'm going to guess that we can init a new Array with anything that responds to generate() ? println(Array("abcde")) // [a, b, c, d, e]
