How can I sort multiple arrays based on the sorted order of another array

Question

I have multiple arrays, and I want to sort all of them based on the sorted order of one of them, like so:

var myArr = [\"b\", \"a\", \"c\"]
var myArr2 = [\"l         


        

Answer 1

From what I understand, you want to order your array alphabetically. If so, you can use one of the example below :

Example 1

var anArray1 = ["b","a","d","e","c"]

func alphabeticallyOrder(lt : String, rt: String) -> Bool {
    return lt < rt
}

anArray1 = sorted(anArray1, alphabeticallyOrder)

println(anArray1) // [a, b, c, d, e]

Example 2

var anArray2 = ["b","a","d","e","c"]

anArray2 = sorted(anArray2, {$0 < $1})

println(anArray2) // [a, b, c, d, e]

Example 3

var anArray3 = ["b","a","d","e","c"]

anArray3 = sorted (anArray3 , <)

println(anArray3) // [a, b, c, d, e]

Edit : My bad, you also want to change the other arrays indexes in the process. I'll edit later if required.
