Hi Srinivas Sri Perumbuduru !

Looks good - you just used a third case for "USA", "MEX","BRA" instead of default like this:

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 "LIE", "BGR", "BEL":
    europeanCapitals.append(value)
case "IND", "VNM":
    asianCapitals.append(value)
default:
    otherCapitals.append(value)
}
    // End code
}

...I just saw that you changed for (key, value) in world { to for cities in world { ...your solution might work in Xcode but the Code Challenge won't accept your answer...

...and you only need to append one value at a time to the array
