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 had this problem... When I selected the project & the correct target I had a blank for the 'launch screen file' under the app icons and launch screen images tab. I set it to the default LaunchScreen and the resizing issue I faced was taken care of.
