Appending value of Switch in a loop to an Array ?

I need someone to give me a hint for this Im kind of stuck . So this asks me to create a loop for a switch which would iterate through the values and append the ones for the respective continent ? I just need a hint and I'll go ahead and finish off the rest .

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: worlds {
case "BEL","LTE","BGR": europeanCapitals.append
    // Enter your code below

    // End code

You need to append the value of the key. The for loop is for the key and the value.

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