What am I doing wrong?

I've checked this with the example and everything seems to be in order.

returns.swift 
func greeting(person:String) -> String {
    return person
    }
println ("Hello \(person("Tom")")

Hi,

You need to add the return type to the function declaration, and then replace println with return

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