Adapt Xcode 7 and later applications on iPhone X

Question

I know it's early to talk about it, but I've downloaded the XCode 9 final build with support for the iPhone X.

I have a problem, all my apps I created with Xcode 7 and then updated with 8.

I still did not use the single display, but I have a storyboard for both iPhone and iPad.

My apps have the default background and are displayed correctly in the storyboard, but when I use the simulator this does not happen. I do not know if there is an entry or an option.

Can somebody give me a hand in courtesy?

Enable launch screen storyboard or add iPhone X resolution launch image to adopt iPhone X layout.
