Cant spot my error

It says that I'm not appending the correct key to the correct array.

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 world {
        case "BEL": europeanCapitals.append(world["BEL"])
        case "LIE": europeanCapitals.append(world["LIE"])
        case "BGR": europeanCapitals.append(world["BGR"])
        case "USA": otherCapitals.append(world["USA"])
        case "MEX": otherCapitals.append(world["MEX"])
        case "BRA": otherCapitals.append(world["BRA"])
        case "IND": asianCapitals.append(world["IND"]) 
        case "VNM": asianCapitals.append(world["VNM"])
        default: print("I dont know what to do")
    // End code
}
}

First, theres a much easier way to use the switch statement, you can combine case by separating them with a comma so you can get all the european capitals and so on in one line. Next, the way i did this challenge was to switch on the key then append the value to the array. This is how I did it. Hope this helps

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