Hello Please does anyone know what I am doing wrong here. I am trying to print just the values of they keys into their prospective continent regions
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" : var europeanCapitals.append(value); case "VNM", "IND" : var asianCapitals.append(value); default: var otherCapitals.append(value); } // End code }
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" : var europeanCapitals.append(value);
case "VNM", "IND" : var asianCapitals.append(value);
default: var otherCapitals.append(value);
}
// End code
}

The first is you need to switch on the dictionary key not the dictionaries name world. the second thing would be after the case you don't need to declare a variable you just need to append the values to the right arrays. Lastly you don't need a ; after each case in a switch statement, most of Swift lets you write code with ought the need for constant semicolon's.
for (key, value) in world {
switch key {
case "BEL", "LIE", "BGR" : europeanCapitals.append(value)
case "VNM", "IND" : asianCapitals.append(value)
default: otherCapitals.append(value)
}
}
hope this helps
