You need to start the switch statement by switching on the key in the dictionary. You then append using the normal append syntax
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","LIE":
europeanCapitals.append(value)
case "IND" :
asianCapitals.append(value)
default:
otherCapitals.append(value)
}
}
