iOS Swift Collections and Control Flow Control Flow With Conditional Statements Working With Switch Statements

I am stumped could you please help? I have watched the videos over and over.

Not sure how to set this up?

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 (key, value) in world {
    switch world {
    case "LIE", "BEL", "BGR", : print("europeanCapitals")
    case "BRA", "IND", "VNM", : print("asianCapitals")

 world.append (" otherCapitals")

 }  
}

Rose, here is the switch statement that I got to execute for the challenge:

switch key {
    case "BEL", "BGR","LIE":
        europeanCapitals.append(value)
    case "IND","VNM":
        asianCapitals.append(value)
    default:
        otherCapitals.append(value)
}

From your question, it looks like you just did the final part wrong. Instead of waiting for the switch statement to fail, and a value not to be caught, you can be safe and utilize the "default" conditional which will execute if none of the conditions in the switch are executed.

I hope this helps.

Kind regards, Landon Ferrier
