527 PointsDefault triggered in switches
I successfully completed this task. However, when I run this in Xcode, the default case--which I set to print(error)--is also triggered once in the debugger as the last iteration of the loop. Since all the keys in the world array have their counterparts in the three different cases, I cannot figure out why or how the default case is being triggered.
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", "LIE", "BRG": europeanCapitals.append(value)
case "USA", "MEX", "BRA": otherCapitals.append(value)
case "IND", "VNM": asianCapitals.append(value)
default: print("error")
// End code
}

Python Development Techdegree Graduate 29,026 PointsThere's a slight mismatch between the values in the dictionary and the values the switch cases are looking for. (BGR / BRG).
The below code should fix this:
for (key, value) in world {
// Enter your code below
switch key {
case "BEL", "LIE", "BGR": europeanCapitals.append(value)
case "USA", "MEX", "BRA": otherCapitals.append(value)
case "IND", "VNM": asianCapitals.append(value)
default: print("error")
// End code
}
}```
