Arrays

What am I doing wrong here? Thanks

array.swift 
// Enter your code below

var arrayOfInts = [1, 2, 3, 4, 5, 6]

arrayOfInts.append(7)


arrayOfInts = arrayOfInts + [8]

let value = arrayOfInts[6]

Hi there, Chris! You clearly remembered that Swift doesn't count array items like humans... it starts with 0. So you've tried to adjust the index by 1. The problem here is that you adjusted the wrong way. You're now retrieving the seventh item instead of the fifth. The fifth item will have an index of four.

Hope this helps! :sparkles:
