iOS: Launch images are deprecated. How can you use launch storyboard or .xib file instead in Kivy app?

Hi!

I was trying to follow instructions such as "Use an asset catalog for a launch screen (iPhone)" - https://help.apple.com/xcode/mac/current/#/devb90cbf66e - to use a set of images as launch screen (for different screen sizes). But the option/setting "Launch Images Source" is missing in Xcode. It turns out that this method of showing an image to the user while the app is loading has been deprecated.

On https://stackoverflow.com/questions/57084407/xcode-11-uilaunchimages-has-been-deprecated-use-launch-storyboards-instead-warn I read:

Please read the release notes for Xcode 11 beta 4:

" Known Issues

Your app might fail to build if it contains a launch image. The failure message resembles the following: “The launch image set named <image set name> did not have any applicable content.” Launch images are deprecated and should be removed; use a launch storyboard or .xib file instead. (50210495)

Workaround: Clear the build setting ASSETCATALOG_COMPILER_LAUNCHIMAGE_NAME. "

Does anyone here on Kivy-users have any good advice on how to proceed to get control over the launch screen of the app?

Thank you!

Well... So far I have done it the 'dirty' / primitive way... I looked at the pixel-format of all the PNG-files in the LaunchImages folder under the Xcode project <my app>-ios folder and replaced them one by one with my launch images of the same size... It works for now, but for how long?
