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

9,160 PointsUhm i dont really get that question...I already posted the right code. The problem is, that you DONT have to PRINT anything.
also you need to add the "-> String" which is the return-type of your function.
return is not the same as println Compare my code and yours and you should see the differences. Also take a look at my link it should help you

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