Java Web Development Techdegree Student 1,966 PointsWorking With Switch Statements
Hi guys, Can someone help me? I think I wrote my code 100% correctly, but the code challenge says that I did not append the results to the correct array. Thanks.
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 {
case "BEL","LTE","BGR": europeanCapitals.append("Brussels","Vaduz","Sofia")
case "IND","VNM": asianCapitals.append("New Delhi","Hanoi")
default: otherCapitals.append("Washnigton D.C.","Mexico City","Brasilia")
}
// End code
}

6,387 PointsRight i'm trying to figure this out, It's been awhile since I used swift but digging through the Swift 3.0.1 Documentation regarding appending I came across this.
alternatively, append an array of one or more compatible items with the addition assignment operator (+=):
shoppingList += ["Baking Powder"]
// shoppingList now contains 4 items
shoppingList += ["Chocolate Spread", "Cheese", "Butter"]
// shoppingList now contains 7 items
You could try that, what is the exact question that the task is asking you to do?

I got stuck with this too. You need to append the values of the keys. There is like a relationship between key and value, as seen in the for-loop. The code is iterates over and over with the keys identified as key, and their values identified as value. For example, if the loop iterates over the code for the first time, it finds the "BEL" key, and appends the value that goes with the key to the europeanCaptitols array. The value would be "Brussels". If the loop iterates over the code a second time, it finds the "LIE" key, and appends the value that goes with that key, "Vaduz".
Hope this helps.

6,387 PointsI think I found your answer,
In your enum(with all the codes and locations it is "LIE": "Vaduz" aka l i e
where as when you append you have written L T E. Took my awhile to find it i think it's just down to simply typo.

Java Web Development Techdegree Student 1,966 PointsThanks so much Luken! I didn't see that typo there.

Java Web Development Techdegree Student 1,966 PointsSadly it still says for me to "Remeber to append the values from each case statement to the correct array"
