Stuck.

HI guys, if someone could please explain to me how to add items into the array, is it .append or .insert? I think I am close to solcing it but I am unsure!

Thanks, Sean

operators.swift
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 capitals in world {

switch capitals {

case "BEL", "BGR", "LIE": europeanCapitals.append()
case "IND","VNM": asianCapitals.append()
default otherCapitals.append  


}
    // Enter your code below

    // End code
}

Hi Sean!

You almost got it. Just remember that append function always has a parameter and you have left it blank here :)
