What is the Syntax for this function?

I'm lost. I can't figure out how to structure this new function to return a string.

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

Hello:

To have a function return a value you have to use the -> return arrow and specify the return type in the function's signature, and the return word in the implementation of the function. 

func someFunc() -> String {

// function's implementation goes here 

return String 
}

Hopefully you are able to finish your challenge with this example.

Good luck.
