What would be the correct syntax here please? switch world { case "BEL", "Brussels": print("yes") }

Hi Rodney,

For this challenge, you're already looping through the members of the world dictionary. You want to switch on the key local variable inside the loop, and append the value to the pertinent array. Start like this:

for (key, value) in world {
    switch key {
        case "BEL", "LIE", "BGR":
            europeanCapitals.append(value)

        // rest of switch statement here

    }

}

Your syntax is wrong.

A. we are switching on the key. switch key {

B. If we are switching on the key. That means "Brussels" has no place in your code as it is a value. "BEL"
is the only thing you need

C. print("yes") doesn't belong either... the goal of the challenge is to append the value to the appropriate array. So for the case with brussels

for (key, value) in world {
switch key {
    case "BEL" : europeanCapitals.append(value)
    default: print("Not Applicable")
    }
}

This would be your syntax... of course you need to apply the same logic to the rest of the key and values.
