Isn't that right??

For the last task, remove the 6th item from the array and assign the result to a constant named discardedValue.

array.swift 
// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]
arrayOfInts.append(7)
arrayOfInts + [8]
arrayOfInts[4] = (44)
let value = 44
arrayOfInts.remove(at: 6)
let discardedValue = 7

You have to assign the values of appending and removing the arrays to the constants. Right now you're removing the item and manually assigning the value that was removed to the constant.

Instead of manually assigning 7 to the discardedValue constant, try assigning the remove(at:) method instead.
