I am getting an error I just don't understand

This is the code I am using

func greeting (#person: String) -> (greeting: String,language: String) { let language = "English" let greeting = "Hello (person)"

return greeting

}

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

    return greeting
}

Hello Alex:

You are doing great, so far you are only missing to properly return on the tuple.

Since you created a tuple as a return type, you want to be able to “Return” the values in the tuple. 

                                    // Tuple as a return type
func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting,language) // Returning the values from the tuple
}

Hope this helps, please let me know if you need more help.
