Hey Edward.

The Apple docs are great for this kind of thing :)

func greeting(person: String) {
    let myGreeting = "Hello, " + person + "!"
    println(myGreeting)
}

If you want to make this a function that returns a string, you can do this:

func greeting(person: String) -> String {
    let myGreeting = "Hello, " + person + "!"
    return myGreeting
}

Then anywhere in your code you can call it like this:

println(greeting("Edward"))

And you will get "Hello, Edward!"

Try it in a Playground. Good Luck, and don't be afraid of the Docs, they are your friend.

So I had to go to Gbase "Google" for help with this question. What I found was some articles about swift that really helped give some insight for how to change the function and subsequent code so that it'd work. This is what I found:

func sayHello(personName: String) -> String { let greeting = "Hello, " + personName + "!" return greeting }

This is from an article about functions in swift. This is NOT the exact answer, but this should give you the necessary ideas for how to modify the function to get the green check!
