it keep saying that i have to " Make sure you're removing the 6th item from the array at index 5!"

I cant see what is wrong

array.swift 
// Enter your code below

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

arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts [4]
arrayOfInts.remove(at: 5)
let discardedValue = arrayOfInts

Hi Ahmad,

remove(at:) returns the item that was removed from the array. It is this item that you need to store in the variable:

let discardedValue = arrayOfInts.remove(at: 5)
