I hope I'm pretty close? countries

Hey guys,

I hope I'm pretty close to solving this one:

I'm not sure what to call the switch? I just put 'world'.

Also not sure what goes inside of the parentheses for the appending to array?`

any help would be very appreciated, thank you

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" : europeanCapitals.append(value)
    case "VNM", "IND" : asianCapitals.append(value)
    default: otherCapitals.append(value)
    }
        // End code
}

Hey Matt,

You're more than close, you've pretty much got it except for what you are switching on. Your for loop is cycling through the 'keys' and 'values' --> The key is what your are checking in the case statements --> so... you just need to change "world" to "key" for the switch.

Your are appending correctly to the new arrays. Once the "key" is found it will append the "value"

Good Job and Keep Coding! :)

switch key {

Thank you so much :)
