Seeing black bars at the top and bottom of the iPhone X Simulator

Question

Running my App in the iPhone X Simulator (GM Seed) I am noticing two strange effects:

• the App does not use the full screen space (top and bottom area is black)

Answer 1

Just ran into this while trying to update an app I hadn't worked on in a while.

On Xcode 9.4, I was able to fix this by doing the following:

1. Add a launch screen by going to File -> New -> File... -> Launch Screen

2. Make sure the newly added launch screen storyboard is selected as the launch screen file under project settings.
