They still aren't "full" view controllers, though. I don't think any of the controller callbacks are executed. I would be surprised if custom drawing is possible. This feature mostly seems to let you leverage autolayout and size classes, which is probably enough for most people

Yep, that's basically it. You can't link any code to it. I think it was added just to make your launch screen look as similar as possible to your app's first screen.
