I am not sure what it means to retrieve the correct key for the content apple pie?

Does it mean to remove apple pie from the dictionary or to simply assign it as a constant? Also, I am not sure what the syntax of this looks like.

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

Hi Kishan!

It means to get the value of apple pie by using the appropriate key.

Example:

var stringsAsInts: [String:Int] = [ "zero" : 0, "one" : 1, "two" : 2, "three" : 3, "four" : 4, "five" : 5, "six" : 6, ]

If you want to retrieve the value of 0, then we have to use

stringsAsInts["zero"]

Hope this helps!

they want you to assign it as a constant. Here is what that looks like.

let applePie = iceCream["AP"]
