sort a string array by first two characters in swift [duplicate]

Question

I have a string array as strList = ["12abc", "23bcd", "12shsh", "23xyz"] Is there any way to sort the array according to just first two characters of each string?

How do you expect this sort by prefix to differ from plain .sort() or .sorted() results? — Gereon

How to do in code? This is very easy and very basic stuff. Please read the linked documentation and the Swift Language Guide about closures. There are examples how to use sort(ed) by closure. — vadian

just try this

var strList = ["12abc", "23bcd", "12shsh", "23xyz","13das","21dadsd"]
var sortArray = strList.sorted()
debugPrint(strList)
print(sortArray)

the console result will show in below

["12abc", "23bcd", "12shsh", "23xyz", "13das", "21dadsd"]
["12abc", "12shsh", "13das", "21dadsd", "23bcd", "23xyz"]

but if, strList = ["12shsh", "23bcd", "12abc", "23xyz","13das","21dadsd"] then the output will be 12shsh, 12abc..... So i need to sort by first 2 digit

Note that you cannot rely on the order of same-sorted elements, since Swift's sort algorithm does not guarantee a stable sort.
