Error in test

When I type this code in Xcode it work as intended removing the 6th item that has an index of 5 in the array.

But in the treehouse exam it gives me the following error: Bummer Make sure you are removing the 6th item with index 5.

What is wrong?

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

var arrayOfInts: [Int] = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts = arrayOfInts + [8]
let value = arrayOfInts[4]
let discardedValue = arrayOfInts.remove(at: 5)

Close!

arrayOfInts.remove(at: 5) // This returns a value which is what is expected to be assigned to discardedValue
