Can anyone help me with this exercise?

Im confused on what to write after switch

switch.swift 
var europeanCapitals: [String] = ["Brussels", "Vaduz", "Sofia"]
var asianCapitals: [String] = ["New Delhi", "Hanoi"]
var otherCapitals: [String] = ["Washington D.C.", "Mexico City", "Brasilia"]

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

for key in world {
    // Enter your code below
    switch key 
    case "BEL", "LIE", "BGR"
    case "IND", "VNM"
    default "USA", "MEX", "BRA"
    // End code
}

Almost. You just didn't finish the case statements:

for (key, value) in world {
    // Enter your code below
    switch key {
    case "BEL","LIE","BGR": europeanCapitals += [value]
    case "IND", "VNM": asianCapitals.append(value)
    default: otherCapitals.append(value)
    }
}

Note that you can add a value to the arrays using .append() or += [value]. Both ways work, and the editor will accept either or both.
