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

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)
  • a strange white bar beneath the title bar

enter image description here

Does anybody know what is happening here and how to resolve this? I can't find any new settings in Interface Builder.

Are you using a Launch Screen file or launch images? Are you using auto layout? – rmaddy
Launch images and auto layout – Darko
Why are you using the old style launch images instead of the much easier Launch Screen file? Anyway, have you added the new launch image needed for the new screen size? – rmaddy
I can't find a launch image for the iPhone X size. But using a launch screen solved both issues. Please edit your response and I will mark it as answered. Thanks! – Darko
You SHOULDN'T USE launch images. USE Launch Screen.storyboard instead – onmyway133

When using launch images (instead of the much easier Launch screen file), you need to provide the properly sized launch image for each device size you wish to support. Once you add the additional launch image, your app should take advantage of the new screen size.

The new iPhone X requires a launch image sized at 1125px × 2436px which is a 3x image for 375pt × 812pt.

Of course if you switch over to using a Launch screen file instead of individual launch images, your app will automatically adapt to all device sizes without any additional work.

Check human interface guidelines for more details.

I have figured out how to fix (though I still don't understand why this happened only on iPhone X) LaunchScreen storyboard on iPhone X with seeing black top&bottom bars.

I have LaunchScreen storyboard with one UIImageView.

UIImageView's top&bottom has to be pinned to SuperView's top&bottom. NOT to SafeArea.

I fixed it by simply inserting some random text in the Lanch Screen File textfield. I dont even have a Launch Screen File... XCode is so buggy.

update

Although this fixes it in simulator (still very weird and unexpected) when uploading a binary to iTunes Connect it will fail due to not finding a LanchScreen file of name "random-name"

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

enter image description here

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

If you already have a 1125px × 2436px launch image but the app is still not using the full screen check to make sure that your image is PNG.

if you removed LaunchScreen.storyboard; Choose your project, select your project target, General -> App Icons and Launch Images -> Launch Screen File: Select here Main.storyboard instead of LaunchScreen.storyboard

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.

You may check in project target launch screen file is not set to empty if it is empty it may cause problem.enter image description here
