How do you retrieve any item and then assign to a constant?

I don't the syntax for retrieving a piece of the array and then assigning it to the variable

arrays.swift 
// Enter your code below
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(2)
arrayOfInts = arrayOfInts + [9]
let r = arrayOfInts.removeAtIndex(2)

Good work so far.

You are going to want to use something like this:

let value = arrayOfInts[5]

What we are doing here is making a constent called value (that's what the let does) and giving it the value of what is stored at index 5 from your array (which will be the Integer 6 because your index counts from 0).

Keep up the great work. :)
