I tried server methods to fix this problem, but nothing seems to work. The launchScreen won't show up on any devices or any project. Even in the simulator the launchScreen is not showing up.
I added background color and a imageView to my launchScreen.
This is what I already tried:
set it to initialViewController
add new viewController and deleted the old one
changed the name in the info.plist
May be, you catched the bug which prevents updating of LaunchScreen. There are some methods to fix it. For me only helped removing of LaunchScreen file, recreating new one, cleaning project and removing the app with device reboot before new install.
