dictionary.swift 
var iceCream = ["CC" : "Chocolate Chip", "AP" : "Apple Pie", "PB" : "Peanut Butter"] 
iceCream.updateValue("Rocky Road", forKey: "RR") 
iceCream["AP"]

Code looks ok except the challenge wasn't expecting the iceCream["AP"] line:

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")

Let's pretend a customer has ordered an ice cream. Retrieve the value for apple pie using the correct key and assign it to a constant named applePie.
var iceCream = ["CC" : "Chocolate Chip", "AP" : "Apple Pie", "PB" : "Peanut Butter"] iceCream.updateValue("Rocky Road", forKey: "RR") iceCream["AP"] let applePie = iceCream["AP"]

It's not taking my code. I don't understand what I'm doing wrong Matt

Pay closer attention to my answer. Your answer has an extra line that is throwing off what the challenge is expecting. When I try your code the challenge hangs and makes me refresh the page. Your code isn't "wrong".

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

iceCream.updateValue("Rocky Road", forKey: "RR")
let applePie = iceCream["AP"]
