how do i do this question?

Hello Mohammad.

Kyle's code is good, you can have a look at it to see what is needed to pass the code challenge.

Here is a quick explanation:

the "-> String" part actually specifies what we what to return with this function and in this case what we want is a string.

The second part of the question asks you to change the print into a return statement, so we only change the keyword here.

Kyle Vandeven -> Thanks for your answer mate. If you could add a little explanation to your code next time, that would be awesome! Not only it makes things easier for the guy who asked the question, but it helps you with terminology, concepts, ecc... as well.

Keep up with the good job!

Thanks

Vittorio

Like this:

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