Compiler error in Treehouse but not Xcode

So this code seemed to be following directions but it keeps saying compiler error no matter what... I put it into Xcode to see if the compiler error showed up there, but it did not. What might I do here besides skip the challenge?

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

Interesting that you don't get an error in Xcode. You are close though. The challenge is looking for you to assign the value in the array at the 5th index to a constant named value.

You clearly know how to create a constant named value and assign something to it:

let value = 5

And you correctly grabbed the 5th item in the array

arrayOfInts[4]

Now, just assign the arrayOfInts[4] to the constant let value = and get ride of the number 5

let value = arrayOfInts[4]

Hi Parker I looked at the code you provided if it was for the third part of this challenge you need to assign the constant value to the call of the 5th item in the arrayOfInts 

let example = testArray[3]
