825 PointsProblem with "Working with Swift Statements"
I get the following error message:
Playground execution failed:
error: CollectionsAndControlFlows.playground:124:10: error: expression pattern of type 'String' cannot match values of type '[String : String]' case "BEL","LIE","BGR": europeanCapitals.append(value) ^~~~~
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 world {
case "BEL","LIE","BGR": europeanCapitals.append(value)
case "IND","VNM": asianCapitals.append(value)
case "USA","MEX","BRA": otherCapitals.append(value)
default:otherCapitals.append(value)
}
// End code
}

switch key {
// case statements
}

3,818 PointsHi alex, I got stuck on this one too mate. It looks like your switch statement has an extra case
case "USA","MEX","BRA": otherCapitals.append(value)
where the default line does the exact same thing. hope this helps.
