How do I add a tuple to a Swift Array?

Question

I\'m trying to add a tuple (e.g., 2-item tuple) to an array.

var myStringArray: (String,Int)[]? = nil
myStringArray += (\"One\", 1)

Thanks to comments:

import UIKit

@assignment func += (inout left: Array<(String, Int)>?, right: (String, Int)) {
    if !left {
        left = []
    }
    if left {
        var array = left!
        array.append(right.0, right.1)
        left = array
    }
}

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        let interestingNumbers = [
            "Prime": [2, 3, 5, 7, 11, 13],
            "Fibonacci": [1, 1, 2, 3, 5, 8],
            "Square": [1, 4, 9, 16, 25],
        ]

        println("interestingNumbers: \(interestingNumbers)\n")
        var largest = 0

        var myStringArray: (String,Int)[]? = nil

        myStringArray += ("One", 1)

        var x = 0

        for (kind, numbers) in interestingNumbers {
            println(kind)
            for number in numbers {
                if number > largest {
                    largest = number
                }
                x++
                println("\(x)) Number: \(number)")
                myStringArray += (kind,number)
            } // end Number
        } // end Kind
        println("myStringArray: \(myStringArray)")
    }
}

The Output:

interestingNumbers: [Square: [1, 4, 9, 16, 25], Prime: [2, 3, 5, 7, 11, 13], Fibonacci: [1, 1, 2, 3, 5, 8]]

Square
1) Number: 1
2) Number: 4
3) Number: 9
4) Number: 16
5) Number: 25
Prime
6) Number: 2
7) Number: 3
8) Number: 5
9) Number: 7
10) Number: 11
11) Number: 13
Fibonacci
12) Number: 1
13) Number: 1
14) Number: 2
15) Number: 3
16) Number: 5
17) Number: 8

Array of tupules:

myStringArray: [(One, 1), (Square, 1), (Square, 4), (Square, 9), (Square, 16), (Square, 25), (Prime, 2), (Prime, 3), (Prime, 5), (Prime, 7), (Prime, 11), (Prime, 13), (Fibonacci, 1), (Fibonacci, 1), (Fibonacci, 2), (Fibonacci, 3), (Fibonacci, 5), (Fibonacci, 8)]
