I don't get the requirement of this question?

Seems like there's nothing to change, but I can't continue this way.

named_parameters.swift
func greeting(person: String) {
    println("Hello \(person)")
}

The exercise may want you to indicate that person is also to be used as an external parameter name for a function parameter, but since your local name of person is appropriate to use to make the code more readable you prefix the name with the hashtag symbol (#). This tells Swift to use the name as both the local parameter name and the external parameter name.

func greeting(#person: String){ println("Hello (person)") }

Hope this helps.

your code is one digit off

change this:

func greeting(person: String) { println("Hello \(person)") }

to this:

func greeting(#person: String) { println("Hello \(person)") }

the challenge wants you to name the parameter "person" to name it you just have to put the hashtag before it as I demonstrated above

Hope it helps!
