Alex, I'm a bit puzzled by your question. You know you're not doing it all right if you don't pass the last task. So I guess that was a bit of tongue in cheek!

The challenge wanted you to remove an item and assign the removed item to a constant. So replace your last two lines with this one:

let discardedValue = arrayOfInts.removeAtIndex(5)

Here you remove the 4th item from arrayOfInts, and assign it, after the removal, to discardedValue.
