I've been on the challenge for the past one hour. Please help

I am sure I did it right. What could possibly be the problem here.

array.swift 
// Enter your code below
var arrayOfInts = [11, 9, 7, 3, 10, 4]
arrayOfInts.append(6)
arrayOfInts += [5]
let arrayOfIntsResult = arrayOfInts[4]

Hey John,

What is the problem? The result of arrayOfIntsResult will be 10.

Edit: Just checked the challenge your arrayOfIntsResult constant should be named "value" :-)

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

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