Changing the order of an array to be the same as another array SWIFT

I've seen this has been done before but can't seem to find it in swift. So I have two arrays, arrayA and arrayB. I want arrayB to sort itself into the same order a arrayA. So for example her is the arrays:

var arrayA = [1,2,3,4,5]
var arrayB = [5,4,3,2,1]

Thanks
