Assign value to a constant

So I'm on task 3 out of 4 and it tells me to assign a value from an array to a constant. For some reason it works in Xcode, but not in the treehouse compiler.

dictionary.swift 
// Enter your code below
var iceCream = [ "CC" : "Chocolate Chip", "AP" : "Apple Pie", "PB" : "Peanut Butter" ]
iceCream["RR"] = "Rocky Road"

iceCream["AP"]

let applePie = iceCream["AP"]

Hi Osama,

Try it without the:

iceCream["AP"]

I think it does not work with the treehouse complier because it is programmed to only recognize the correct way to specifically solve these challenges. You can add something totally random, like identify a variable in Xcode, and it would work. But if you do it in the treehouse complier, it would not work because it is set to recognize if you did what the instructions asked you to do.

var iceCream = ["CC": "Chocolate Chip", "AP": "Apple Pie", "PB": "Peanut Butter"]
//iceCream["RR"] = "Rocky Road"
iceCream.updateValue("Rocky Road", forKey: "RR")
iceCream.removeValue(forKey: "AP")
iceCream["AP"] = "Apple Pie"
let applePie = iceCream["AP"]

//Hope that helps
