I tried this exact code in playground and it worked. What am I missing?

Any ideas?

arrays.swift 
// Enter your code below

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

arrayOfInts.append(7)

arrayOfInts += [8]

arrayOfInts.removeAtIndex(5)

let value = arrayOfInts

Hey Stephanie,

The code is correct and will work in the playground, but it is not what the final part of the challenge asks for. It wants the removed value assigned to a constant named discardedValue. You just removed the value and didn't assign it to the constant.

let discardedValue = arrayOfInts.removeAtIndex(5)

Keep Coding!
