Xcode compiles this tuple correctly, but online editor does not.

Hey

The current task for the tuples section is to assign the result of the greeting to a variable called result, i have tried the below, which returns a single string variable in result of "Hello Tom" and ive tried changing the result to be a tuple itself eg:

var result = greeting("Tom")

Neither pass the test, im wondering what im doing wrong? I have already completed the extra credit assignment but cannot get past this code validation issue.

Thanks!

tuples.swift 
func greeting(person: String) -> (language: String, greeting : String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (language,greeting)
}

var (_,result) = greeting("Tom")

the problem is the variable name (, result). ( and , are not appropriate variable characters. when returning a tuple a normal name like result will be able to hold it. You do not need to have a strange (,result) format.

so var result = greeting("Tom") should work fine.
