iOS Swift Collections and Control Flow Control Flow With Conditional Statements Working With Switch Statements

Not sure what I'm missing here. trying to append the values.

I think it's right, tried different combinations...

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", "LIE", "BGR": europeanCapitals.append(value)
    case "USA", "MEX", "BRA": otherCapitals.append(value)
    case "IND", "VNM": asianCapitals.append(value)
    default: print("Out of this world!")
    // End code
}

the challenge tells you to switch on the key, but you are switching on the collection. the switch is what the various cases are matched against to determine what to do. also it doesn't ask you to print anything but that the default be appending to other capitals, so those shouldn't be their own case. you also seem to be missing a closing } curly brace.
