Switch Object Question

I can't solve this problem. Probably I didn't understand this problem and switch statement. What is the answet to the question?

Note: My English is very bad. So If you write corret code directly, I'm glad.

switch.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 "BEL", "LIE", "BGR" : europeanCapitals.append("Brussels", "Vaduz", "Sofia")
    }
    // End code
}

Hey Anıl Emre Günay,

You're close. You just need to append the value inside your append method and make more case statements for the other possible keys. I posted the code below as you've asked. Maybe try and translate this with Google translate!

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 "BEL", "LIE", "BGR" : europeanCapitals.append(value)
    case "IND", "VNM": asianCapitals.append(value)
    default: otherCapitals.append(value)
    }
    // End code
}

Good Luck
