Use sort for multidimensional array (array in array) in Swift?

Question

I want to know that how can we use sort or sorted function for multidimensional array in Swift?

For example theirs an array:

Answer 1

I think you should use an array of tuples, then you won't have any problems with type casts:

let array : [(Int, String)] = [
    (5, "test123"),
    (2, "test443"),
    (3, "test663"),
    (1, "test123")
]

let sortedArray = array.sorted { $0.0 < $1.0 }

Swift is all about type safety

(Change sorted to sort if you're using Swift 2.0)
