Swift 2.0 dictionary iceCream challenge won't pass.

Code won't pass on challenge but works in Xcode attached is the code:

var iceCream = ["CC": "Chocolate Chip",
                "AP": "Apple Pie",
                "PB": "Peanut Butter"]

iceCream.updateValue("Rocky Road", forKey: "RR")

iceCream["AP"]
let applePie = iceCream["AP"]

it is asking me to create a constant withe the value applePie with the result iceCream["AP"] but it says: "expression resolves to an unused l-valueiceCream["AP"]"

Your code should pass perfectly if you delete the extra iceCream["AP"] that comes before your constant assignment.

Ex.

var iceCream = ["CC": "Chocolate Chip",
               "AP": "Apple Pie",
               "PB": "Peanut Butter"]
iceCream["RR"] = "Rocky Road"
let applePie = iceCream["AP"]

Also, this link can help with formatting code posted in the forums.

Hope this helps!
