iOS Swift Collections and Control Flow Introduction to Collections Working With Arrays


What am I doing wrong here? Thanks

// Enter your code below

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


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:
