Cannot come up with this one after countless tweaks...

I thought this one would be a piece of cake. This is the code that I initially put and I feel it's the most minimal and effective of my tries.

Please & Thanks!

returns.swift 
func greeting(person: String) -> String {
    return person
}

println("Hello \(greeting))")

Thank you Vivek! After seeing your correction it's pretty clear what I was doing wrong.
