I don't know what I have done wrong

I think I might have nearly got it right but I don't know what I am doing wrong?

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", 
  "VNM": "Hanoi"]

for (key, value) in world {
    // Enter your code below
    switch key { "BEL", "LIE", "BGR": europeanCapitals.append(value)
     "USA","MEX","BRA": otherCapitals.append(value)
     "IND", "VNM": asianCapitals.append(value)
     default. otherCapitals



    // End code
}

It is the values in your cases that are incorrect also you only need 2 cases the other one can be the default

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",
    "VNM": "Hanoi"]

for (key, value) in world {
    switch key {
    case "BEL","BGR","LIE":
        europeanCapitals.append(value)
    case "IND" :
        asianCapitals.append(value)
    default:
        otherCapitals.append(value)
    }
}
