What am I doing wrong?? 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, value) { case "BEL", "LIE", "BGR": europeanCapitals.append(value) case "IND", "VNM": asianCapitals.append(value) default: otherCapitals.append(value)
}
// End code

Note that while Jakob's code will pass the challenge, it deviates a bit from what the instructions asked for.
Your original code (once fixed) is a more correct solution.

Cheers!

3,283 PointsThanks for this explanation I was having the hardest time as well. The loop section has been really hard. I've gotten so close and these 1 or two little things have prevented me from fully completing it! It makes a little more sense now. I will go back and read up on this section in the swift notes that Pasan provides!

3,500 PointsHey Carlos!
You need to change some information in switch statment. You are looking only for a "key" in the world array of dictionary. So you dont need to search for a value. Also the array with otherCapitals are the capitals that not match to Asian or European capitals i.e: "USA", "MEX", "BRA", so your code should look like this:
Let me know if this worked for you :)
