I've written my code, but I cannot go on. Suggestions, thanks
Giovanni
var europeanCapitals: [String] = ["Brussels", "Vaduz", "Sofia"]
var asianCapitals: [String] = ["New Delhi", "Hanoi"]
var otherCapitals: [String] = ["Washington D.C.", "Mexico City", "Brasilia"]
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 europeanCapitals {
case "BEL": print("Brussels")
case "LIE": print("Vaduz")
case "BGR": print("Sofia")

europeanCapitals.append("Brussels", "Vaduz", "Sofia")

A few things:
1) The initial array declarations should be fore empty arrays
2) In the "for in" loop, you will switch on "value". You can use a single switch statement.
3) You can use a single case statement to find and append cities into their respective categories
4) You will append the string values for each key value (you don't have to write them out).
Hopefully the code below will help illustrate these things:
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 {
switch key {
case "BEL", "BGR": europeanCapitals.append(value)
case "IND", "VNM": asianCapitals.append(value)
default: otherCapitals.append(value)
}
}
Good luck!

1,104 PointsThanks for your kind reply. I'm totally beginner and I'm studying, but for me it's very difficult. Bye
