Array

I can't get this work. Thanks.

arrays.swift 
// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]
arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts[4]
discardedValue = arrayOfInts.removeAtIndex(5)

Hey Mahmoud,

you almost got it right! You just forgot to declare the constant discardedValue with the let keyword.

It should work if you write

let discardedValue = arrayOfInts.removeAtIndex(5)

Good luck!
