Hi Suraz,

You are really close!

Keep in mind the updateValue method is used to not only add a new key value pair, but is also used to update existing key value pairs.

ultimately it will look something like this:

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

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

let applePie = iceCream["AP"]

iceCream.updateValue("Chocolate Chip Cookie Dough", forKey: "CC")

I hope this helps!
