A couple of things to consider:
1) The starter code in the challenge gives you a for loop that uses (key, value), so you will want to use that rather than create a new variable called "capitals"
2) Switch statement will switch off the key and then use the value to append to the proper array.
Here is the corrected code:
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(value)
case "IND", "VNM": asianCapitals.append(value)
default: otherCapitals.append(value)
}
// End code
}
