How does the Working with Switch Statements CC work? I tried some code, but it caused a bunch of errors (it got deleted when I accidentally clicked on a link). The instructions are rather long, so I suggest looking a the challenge. I don't have a remote idea of how to do the challenge.
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
}

Treehouse TeacherActually Jacob Dobson is correct here. "BRA" returns "Brasilia" which is the capital city of Brazil. There was a bug in the challenge editor which allowed you to pass the question with the above answer.
The correct answer means no BRA in europeanCapitals and you need to include New Delhi in Asia.
Sorry for the confusion everyone!

In this challenge, I think what Pasan Premaratne wants us to do is practice using switch statements. Here's how I went about it.
for (key, value) in world {
switch key {
case "BEL", "BGR", "BRA": europeanCapitals.append(value)
case "VNM": asianCapitals.append(value)
default: otherCapitals.append(value)
}
}

The reason why I do not use the rest of the values in the dictionary is because they are satisfied in the default case. To answer your second question, he provides the values for what the acronyms stand for in the follow dictionary:
let world = [
"BEL": "Brussels", // european capital
"LIE": "Vaduz",
"BGR": "Sofia", // european capital
"USA": "Washington D.C.",
"MEX": "Mexico City",
"BRA": "Brasilia", // european capital
"IND": "New Delhi",
"VNM": "Hanoi"

Good luck! :)
