How do I append the values from each case statement to the correct array?

Code please!

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","LIE","BGR": 
}
    // End code
}

switch "key" not "world" to check the keys then append the values into the appropriate array.

Hi Josu,

The format to append a value to an array looks like this.

arrayName.append(value)

Here is what this looks like in the code 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
}

I hope that helps.

Mike
