iOS Swift Functions and Optionals Parameters and Tuples Named Parameters

I've created a function called greeting that uses 'person' as its parameter, but apparently something's still wrong.

I continue getting the same generic "Bummer" message which is just a repetition of the the original task description. No help whatsoever...

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

Is the challenge asking you to make it a return ? If its only asking you to create a function that takes “person” as a parameter then you are adding extra things to the function..

func greeting(person: String) {
println(person)

}

I agree with Jhoan Arango , what exactly is the challenge asking?

You need to simply prefix the person parameter with # to make it an external parameter.

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