Need assistance with swift statement challenge. It's driving me crazy!

I can't see what else I need to add to this code in order for it to pass the challenge. Any help would be much appreciated

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 (capitalCity) in world {
    // Enter your code below
    switch capitalCity {
      case "BEL", "LIE", "BGR": europeanCapitals.append(not the key!)
      case "IND", "VNM": asianCapitals.append()
      default: otherCaptials.append()
    }
}

You were quite close. Consider the changes to your code below.

for cityCode, cityName in world {  // This is a dictionary so uses key, value pairs.
    switch cityCode {
      case "BEL", "LIE", "BGR": europeanCapitals.append(cityName)
      case "IND", "VNM": asianCapitals.append(cityName)
      default: otherCaptials.append(cityName)
    }
}

Righto. So let's simplify what you need to input, and understand it. :)

You already have all the code there in a fresh challenge screen. Be sure to reload it in your browser so that it is fresh.

Just like this:

// Enter your code below

    switch key {
        case "BEL", "LIE", "BGR": europeanCapitals.append(value)
        case "IND", "VNM": asianCapitals(value)
        default: otherCapitals.append(value)
    }

// Enter your code above
