Another badly worded question.

I understand arrays but this challenge is really badly put. I don't understand why it keeps telling me that this wrong. // Enter your code below var arrayOfInts: [Int] = [1,2,3,4,55,78]

arrayOfInts.append(44)

arrayOfInts += [55]

let seventyEight = arrayOfInts[5]

arrays.swift 
// Enter your code below
var arrayOfInts: [Int] = [1,2,3,4,55,78]

arrayOfInts.append(44)

arrayOfInts += [55]

let seventyEight = arrayOfInts[5]

Correct Code

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

arrayOfInts.append(44)

arrayOfInts += [7]

let value = arrayOfInts[4]

let discardedValue = arrayOfInts.removeAtIndex(5)

I don't get why you need to assign "value" and "discardedValue" wouldn't arrayOfInts.removeAtIndex(5) be all that you need to do type?

It does nothing really, just that's how the code challenge wants you to do
