iOS Swift Collections and Control Flow Dictionaries in Swift Working With Dictionaries

Hi can anyone help me out ?

The question : 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.

dictionary.swift
// Enter your code below
// Task 1 
var iceCream  = ["CC" : "Chocolate Chip" , "AP" : "Apple Pie" , "PB" : "Peanut Butter" ]
// Task 2 
iceCream.updateValue("Rocky Road", forKey: "RR")
//Task 3
let applePie = airportCodes["AP"] = nil

Hi there! I feel like you were doing fine and then stopped to look at an example possibly? You're trying to set the value of the key "AP" to nil. This was not asked for by the challenge. But above and beyond that, you are trying to access a dictionary that doesn't exist. The dictionary airportCodes does not exist inside this challenge. Our only dictionary is iceCream.

Step 3 wants you to get the value stored at the key "AP" from the iceCream dictionary and store it into the constant applePie. This is what the line looked like for Step 3:

let applePie = iceCream["AP"]

Hope this helps! :sparkles:
