Hi Benjamin,

This switch case statement will switch between the cases and grab the values of the keys defined into their arrays.

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":
        europeanCapitals.append(value)

    case "IND","VNM":
        asianCapitals.append(value)

    default:
        otherCapitals.append(value)
    }

    // End code

}

Hope this helps!
