Need help on Working with switch statements.

Here is my code:

////////////// Code Challenge Working with switch statements //////////////////

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": europeanCapitals.append("Brussels") case "VNM", "IND": default "USA", "BRA", "MEX": } // End code }

Hi Blake, You need to build a switch statement as following: you pick the "key" and switch on it , then based on the case you will append the "value" to the right array. I hope this helps. '''

switch key { case "BEL","LIE","BGR": europeanCapitals.append(value) case "VNM", "IND": asianCapitals.append(value) default : otherCapitals.append(value) }
