Hey, so the first thing you need to do is to declare the return type.

This is done by adding -> String to your function declaration. You also need to replace the println statement with a return (since you want to return this string, instead of printing it).

You're also missing a \ infron of (person) so your string interpolation won't work correctly.

This is what your code should look like once you're made those changes.

func greeting(person: String) -> String {
    return "Hello \(person)"
}

don't now how to do it... Anybody please explain this
