I am really stuck in this challenge . I think I am not getting the syntax right.
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
}

You have a loop that's iterating through the array of key/value pairs. At each iteration, the key & value are held in two local variable inside the for loop, called key and value, predictably!
You want to switch on the key. For the European City keys, which are BEL, LIE and BGR, you want to append the corresponding value into the europeanCapitals array. You can do this all in one line, rather than having a case for every key. You then do the same for the the other keys; be careful about the required default case.
The first line could look like:
switch key{
case "BEL", "LIE", "BGR":
europeanCapitals.append(value)
// others go here
}
I hope that helps - let me know how you get on.
Steve.
