Change

var fifth = arrayOfInts[4]

to

let value = arrayOfInts[4]

This is the exercise description:

We also learned about reading values from an array. Retrieve the 5th item (remember array indexes start at 0) and assign the result to a constant named value.

The name of the final variable is supposed to be "value" and not "fifth." Other than that I think thats it. 

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