What is wrong w/ this: func greeting(person:String){ println("Hello \(person).") ? It works in my Xcode.

I'm stumped, please help.

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

the bummer message states: Your greeting printed "Hello XYZZY." when called with "XYZZY" as the parameter. It should have printed "Hello XYZZY".

remove the period from the end of the string

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