switch.swift 
var europeanCapitals: [String] = []
var asianCapitals: [String] = []
var otherCapitals: [String] = []

let world = [
  "BEL": "Brussels", 
  "LIE": "Vaduz",

  "USA": "Washington D.C.", 
  "MEX": "Mexico City", 
  "BRA": "Brasilia",

  "VNM": "Hanoi"]

for (key, value) in world {
    // Enter your code below
    switch key { 
    case "Brussels", "Vaduz", "Sofia": europeanCapitals.append
    case "Hanoi", "New Delhi": asianCapitals.append

Hi Isaac,

Looks like all you have to do is be more specific about what you want to append, which is the value to the appropriate array. E.g. instead of

europeanCapitals.append

try

europeanCapitals.append(value)

Hope this helps,

Ajay
