Hello, I tried to complete the challenge, but I dont know whats wrong, It seems everything good to me

let applePie = iceCream.removeValueForKey("AP")

It seems like it's everything like according to lectures

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

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

let applePie = iceCream.removeValueForKey("AP")

Hi,

The correct code would be:

// 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"]
