Hi Javier!

you have to use switch with key (because of for (key, value) in world) , curly brackets aren't used after case: and default: stands for itself.

It should look like this:

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