I can't get past this code challenge. I think the last line is wrong.

How do I assign the result to discardedValue?

arrays.swift 
// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]

arrayOfInts.append(7)

arrayOfInts += [8]

let value = arrayOfInts[4]

arrayOfInts.removeAtIndex(index: Int 5)

let discardedValue = [5]

Hey Joni,

You're really close. Just a couple of things.

  • First, you don't need 2 lines of code for the final task. You just need to sort of combine them.

  • Second, when you are using removeAtIndex(), you just pass in the index number. You don't need "index" or "int"

The final line of code will then read:

let discardedValue = arrayOfInts.removeAtIndex(5)

Keep Coding! :)
