Its close your switching the correct thing. The problem is you are appending the key when you want the switch statement to give you the value ex. "Washington D.C.". In your code you use the append method for key its looking for the key in the case and appending the key value, you want it to append the value.

for (key, value) in world {
    switch key {
    case "BEL", "LIE", "BGR": europeanCapitals.append(value)
    case "IND", "VNM"; asianCapitals.append(value)
    default: otherCapitals.append(value)

    }
}

Dictionaries are always two parts keys and values
