I don't know what i have to do here. Tried the following code but it is not working.
for (key, value) in world { // Enter your code below switch key { case "BEL","LIE","BGR": europeanCapitals.append(world[key]) case "USA","MEX","BRA": europeanCapitals.append(world[key]) default: otherCapitals.append(world[key]) // End 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(world[key])
case "USA","MEX","BRA": europeanCapitals.append(world[key])
default: otherCapitals.append(world[key])
// End code
}
}

Treehouse TeacherHi there! You're pretty close, so I'm going to give some pointers here.
- You should be appending the
value - Your code only appends to
europeanCapitalsandotherCapitals - Currently Washington, D.C., Mexico City, and Brasilia are being appended to the
europeanCapitals - You lack any code that appends to the
asianCapitals
Give it another shot with these hints in mind!

You are close on this one. You definitely want to do the switch on the key like you are already doing, but you haven't used the value variable yet. Instead of append(world[key]), you just want to append(value), as we don't want our arrays filled with the keys. Also, it looks like you are using the europeanCapitals twice. If you change your second case to otherCapitals.append(value) and change the default to asianCapitals.append(value), your code should pass. Hope this helps!
