Hey William,

the only thing you are forgetting is the return type. Also, I wouldn't recommend creating a variable with the same name as the function itself.

So you just need to specify a return type of String like this:

func greeting(person: String) -> String {
    return "Hello \(person)"
}

Hope that helps!
