Hi Robert!

you might want to change your solution to

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

because you were asked to replace the println statement with a return statement.

Holger Liesegang thanks for the help. I truly appreciate it. if you don't mind could you briefly explain how functions are integrated into creating apps.

Hi Robert Gunn !

I'm not quite sure what you mean, can you be more specific, please?

...maybe you are looking for something like Programming Paradigms ?
