Working with Switch Statements, IOS, challenge

I am not sure what i am doing wrong in this 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
    switch countryCodes {

    case "BEL", "LIE", "BGR": ("europeanCapitals")
    case "USA", "MEX": ("otherCapitals") 
    case "BRA", "IND", "VNM": ("asianCapitals") 


    }
    // End code
}

Follow the errors given.

When I run your code, it tells me to append the value to the country array. You are currently just typing in a string of the country array.

array.append(value)

The next error tells us it will not compile. Let's check the preview.

The preview tells us your switch is broken. Maybe because you are using a variable in switch that does not exist? Try using 'key'.

Finally, you are missing a default statement for your switch.
