Black iOS launch screen instead of white

I have an issue with changing background color of launch screen on iOS. When I open the app for the first time it loads a white page before the black viewcontroller appears. How can I change the white launch screen to a black one?

Below is my app General launch image settings:

I am still new with iOS. Any ideas?

Create a launch screen storyboard and select that as launch screen file.

Then change the background to black. You can also customize it whatever way you want
