Is this an instance where I use the append method and if so am I just using it incorrectly?

I honestly have no clue on what to do, sometimes these tasks are too hard. I would love some help.

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

Hi Charles,

You are so close with that! You've done the hard bit.

You want to append the value after switching on the key. And you need a colon after each case:

    for (key, value) in world {
    // Enter your code below
    switch key {
      case "LIE", "BEL", "BGR": europeanCapitals.append(value)
      case "IND", "VNM":  asianCapitals.append(value)
      case "BRA", "MEX", "USA": otherCapitals.append(value)
      default: break
    }
 }

That should work for you.

Steve.
