I don't get it at all. Could someone answer this code challenge please?
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 airportCodes {
case "BEL": europeanCapitals.append(key)
}
// End code
}

4,039 PointsHi Aiden,
I see you started fine by using a Switch statement and properly appending the values (airport names) to a corresponding array.
However you have missed two fundamentals.
1- While using Switch statements you can switch multiple conditions using comma. In this case you must switch every other airport code belonging to the same array:
for (key, value) in world {
switch key {
case "BEL", "LIE", "BGR": europeanCapitals.append(value)
case "IND", "VNM": asianCapitals.append(value)
}
2- Last but not least, all Switch statements must contain a default value to cover any values that are not addressed explicitly in previous cases (MEX, USA, etc...):
for (key, value) in world {
switch key {
case "BEL", "LIE", "BGR": europeanCapitals.append(value)
case "IND", "VNM": asianCapitals.append(value)
default: otherCapitals.append(value)
}
}
Hope this is now clear for you.
