How do I append the vlaues

I am confident i have everything else right i just always get stuck at appending things.

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 world {
    case "BEL", "BRA", "LIE", "BGR": europeanCapitals.append[]
    case "BGR", "IND", "VNM": asianCapitals.append[]
    default: otherCapitals.append[]
    }
    // End code
}

Hi Tyler,

In your example, you switched on the array, but you just had to switch on the key itself. That's the main reason why you had an error. Next you need to use the function append(value) on every array.

Here is the code:

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
}
