How do I create an array of tuples?

Question

I\'m trying to create an array of tuples in Swift, but having great difficulty:

var fun: (num1: Int, num2: Int)[] = (num1: Int, num2: Int)[]()

Answer 1

This also works:

var fun:Array<(Int,Int)> = []
fun += (1,2)
fun += (3,4)

Oddly though, append wants just one set of parens:

fun.append(5,6)

If you want the labels for the tuple parts:

var fun:Array<(num1: Int, num2: Int)> = []
fun += (1,2)                  // This still works
fun.append(3,4)               // This does not work
fun.append(num1: 3, num2: 4)  // but this does work
