Why the code that I wrote is wrong?

I don't think it is wrong

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 world{
      case "BEL","Vaduz","Sofia", "Brasilia": europeanCapials.append[value]
      case "Washington D.C.", "Mexico City": otherCapitals.append[value]
      case "New Delhi", "Hanoi": asianCapitals.append[value]
    }

    // End code
}

  1. You need to switch on key
  2. You need to use the key for the case
  3. You need to append the values to the specific capital
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 key {
    case "BEL","BGR","LIE":
        europeanCapitals.append(value)
    case "IND" :
        asianCapitals.append(value)
    default:
        otherCapitals.append(value)
    }
}
