Albert, you need to be really careful about upper and lower case, and spelling. 

for (key, value) in world {
    // Enter your code below
    switch key {
    case "BEL", "LIE", "BGR" : europeanCapitals.append(value)
    case "VNM", "IND" : asianCapitals.append(value)
    default : otherCapitals.append(value)
    }
    // End code
}

Note that value is not capitalized, nor is default. Further, it's otherCapitals plural!

The only things you did wrong here are typos. Swift is case-sensitive, so you need to watch out for that.

You have three main typos in your for in loop: (1) you need to either uncapitalize all the "Value" variables you're appending to each array, or you need to capitalize "value" at the beginning of your for loop; (2) you need to uncapitalize "Default"; and (3) you need to put an "s" at the end of "otherCapital" in your switch statement.

for (key, value) in world { // THIS "value" DOES NOT MATCH THE OTHER "Value"s YOU'RE APPENDING TO EACH ARRAY
    // Enter your code below
    switch key {
    case "BEL", "LIE", "BGR" : europeanCapitals.append(Value)
    case "VNM", "IND" : asianCapitals.append(Value)
    Default : otherCapital.append(Value) // "Default" NEEDS TO BE "default" AND "otherCapital" NEEDS TO BE "otherCapitals"
    }
    // End code
}

I hope this helps!
