What have I done wrong in this code?

I don't understand how to append the values to the right array

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 key {
    case "BEL", "LIE", "BGR" : var europeanCapitals.append(value)
    case "IND", "VNM": var asianCapitals.append(value)
    default "USA", "MEX", "BRA" : var otherCapitals.append(value)
    }
    // End code
}

There's several problems with your code. First one, remove the var before the arrays, because you would be initialising them again by calling the keyword var. Then, remove the empty space before the colon in the case lines. Also, the last line, you put default and then possible cases ("USA", "MEX"), which is wrong. A switch will apply the default case when none of the other checks where true, so you can just remove "USA", "MEX", "BRA" and just leave default:.

Hopefully this will help!
