For in loops with switch statements

Question

Hello Please does anyone know what I am doing wrong here. I am trying to print just the values of they keys into their prospective continent regions 
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" : var europeanCapitals.append(value);
    case "VNM", "IND" : var asianCapitals.append(value);
   default: var otherCapitals.append(value);
    }
    // End code
}
```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" : var europeanCapitals.append(value);
    case "VNM", "IND" : var asianCapitals.append(value);
   default: var otherCapitals.append(value);
    }
    // End code
}
```

Hi there, there are three things that are not letting you pass the challenge. The first is you need to switch on the dictionary key not the dictionaries name world. the second thing would be after the case you don't need to declare a variable you just need to append the values to the right arrays. Lastly you don't need a ; after each case in a switch statement, most of Swift lets you write code with ought the need for constant semicolon's. 
```swift 
for (key, value) in world {
    switch key {
    case "BEL", "LIE", "BGR" : europeanCapitals.append(value)
    case "VNM", "IND" : asianCapitals.append(value)
   default: otherCapitals.append(value)
    }
}
```
hope this helps
