When I run my code in Xcode it works fine, but treehouse is saying I need to append the values to their proper arrays

When I run my code in Xcode it works fine, but treehouse is saying I need to append the values to their proper arrays

operators.swift 
var europeanCapitals: [String] = ["BEL" , "LIE" , "BGR"]
var asianCapitals: [String] = ["IND" , "VNW" , ]
var otherCapitals: [String] = ["USA" , "MEX" , "BRA"]

let world = [
  "BEL": "Brussels",
  "LIE": "Vaduz",
  "BGR": "Sofia",
  "USA": "Washington D.C.",
  "MEX": "Mexico City",
  "BRA": "Brasilia",
  "IND": "New Delhi",
  "VNM": "Hanoi"]

for (city, value) in world {
    switch city {
    case "BEL": print("Brussels")
    case "LIE": print("Vaduz")
    case "BGR": print("Sofia")
    case "USA": print("Washington D.C.")
    case "MEX": print("Mexico City")
    case "BRA": print("Brasilia")
    case "IND": print("New Delhi")
    case "VNM": print("Hanoi")

    default: print("Bitch, I think we're lost")

In general for challenges you shouldn't modify existing code unless asked to do so. For example the variable declarations at the top should stay as provided. The instructions want you to append values to the appropriate array based on the key and give an example:

For cases where the key is a European country, append the value (not the key!) to the europeanCapitals array

So instead of a print statement like this

case "BEL": print("Brussels")

you would have

case "BEL": europeanCapitals.append(value)

The instructions also state what to do with the default case

for the default case, append the values to otherCapitals
