Help with airport switch

Say's That my case for europeaCapitals is incorrect. Any suggestions?

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{ case "LIE", "BEL", "BGR": europeanCapitals.append("Vaduz, Brussels, Sofia") case "VNM", "IND": asianCapitals.append("Hanoi, New Delhi") default: otherCapitals.append("Washington D.C. , Mexico City, Brasilia") } // End code }

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{
    case "LIE", "BEL", "BGR": europeanCapitals.append("Vaduz, Brussels, Sofia")
    case "VNM", "IND": asianCapitals.append("Hanoi, New Delhi")
    default: otherCapitals.append("Washington D.C. , Mexico City, Brasilia")
    }
    // End code
}

In your switch statement you want to append the "value" of the key-value pair to the various arrays (e.g. europeancapitals).

So change this statement (and the others) to something like this:

case "LIE", "BEL", "BGR": europeanCapitals.append(value)
