I get the message : "String' is not convertible to 'String'" I can't find a way around...

   return greeting
}

The problem here is you're trying to return the function name as a string, so the compiler is getting into an endless circular loop. Just changing the return statement to anything else should work as in the example provided next:

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

greeting("Pedro")
