Sadly i have no idea what to do!

Give me clues on how to complete this code challenge, i would also like you to make the instructions simpler for me : )

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

    // End code
}

Ok so in the dictionary there are set of Country codes that refer to different Capitals. What the code challenge is essentially asking you to do, is to go through all the country codes and append their capitals to each of the listed arrays. There are 3 different arrays so I will give you an example of how to do one:

for (key, value) in world { switch key{ case "BEL","LIE","BGR": europeanCapitals.append(world[key]!) //add the rest } }

Hope this helps!
