How can I retrieve the value of a dictionary from the key?

I'm sure it's something small that I am missing here. The error that I am receiving when I check my work is, "Make sure you're retrieving a value and not a string directly".

// Enter your code below
var iceCream = ["CC": "Chocolate Chip", "AP": "Apple Pie", "PB": "Peanut Butter"]

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

let applePie = iceCream("AP")

All you need to do is change the parentheses around the apple pie key to brackets.

so: let applePie = iceCream("AP")

should be: let applePie = iceCream["AP"]

Your mistake was really small here, you probably have figured it out by now. Keep up the good work!
