Switch Statement Challenge

What did I do wrong in this switch challenge?

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
    let europeanCapitals = ["Brussels", "Vaduz", "Sofia"]
    let asianCapitals = ["New Delhi", "Hanoi"]
    let otherCapitals = ["Washington D.C.", "Mexico City", "Brasilia"]

    switch world {
        case "europeanCapitals": print(europeanCapitals.append())
        case "asianCapitals": print(asianCapitals.append())
        defualt: print(otherCapitals.append())
    }
    // End code
}

You've may be overthinking it a bit. There is no need to create new constants with the same names as their previously declared variables. This is an answer to pass the challenge. 

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
}
