what is wrong there??

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["Brussels","Vaduz","Sofia"] case "IND", "VNM" : asianCapitals.append["New Delhi","Hanoi"] default: otherCapitals.append["Washington D.C.","Mexico City","Brasilia"] } // End code }

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 key{
    case "BEL", "LIE", "BGR" : europeanCapitals.append["Brussels","Vaduz","Sofia"]
    case "IND", "VNM" : asianCapitals.append["New Delhi","Hanoi"]
    default: otherCapitals.append["Washington D.C.","Mexico City","Brasilia"]
    }
    // End code
}

Hi there, the argument to Array.append should be the value keyword, not an entirely new Array.

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
}

This should fix the code's problem. Hope it helps.
