Oddly enough, Apple has rejected Samsung's request to view the source code for iOS 6. The request came as part of an on-going legal battle between the two in South Korea. Samsung accuses Apple of infringing upon a patent the electronics giant received back in November of 2006 that relates to the notification center.
Samsung believes that the Apple Notification Center in iOS, added to the operating system in 2011, infringes upon the patent. Samsung argues they need to see the source code of iOS 6 in order to decide whether or not it infringes upon the patent that they own. Apple, of course, isn't happy with this.
According to The Korea Times, Apple's legal representatives apparently described this request as "insane." However, if it goes to court, Apple could be on the hook to produce the source code anyway. If they produce it now and show that it doesn't infringe, they could avoid a possibly costly legal battle.
