In the editor we have a dictionary that contains a three letter country code as a key and that country's capital city as

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

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

@walterfernandez What you need to do here is use a switch statement. I would suggest going back to this video if you have any trouble. The correct code is below:

// The for in loop, goes through all items in the dictionary.
// The switch statement finds the matching case and appends the value to the correct array
for (key, value) in world {
    // Enter your code below
    switch key {
    case "BEL", "LIE", "BGR": europeanCapitals.append(value)
    case "IND", "VNM": asianCapitals.append(value)
    default: otherCapitals.append(value)
    }
    // End code
}
