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?

Answer 2

Two ways you are fixing the above issue.

1: When you using launch images,You should add proper sized launch images like 1125px × 2436px which is a 3x image for 375pt × 812pt.(for portrait)

2: Otherwise you should move to  Launch screen storyboard file instead of individual launch images.
