You can add them, but we're not allowed to view them - see FAQs 1 & 2 here: For Best Results - Read the Label

About that error, it might be a bug in Xcode - As an example, see this SO thread for things to try, being sure to use the Product menu to 'clean build folder' after making changes.

Is the image in Assets.xcassets ?

there is the screenshot, (thanks for the tip KMT) : https://ibb.co/m6SLnYq

It's in a folder called media.xcasset, Good point Claude I didn't notice it was not the usual assets.xcassets. I created it and placed the launchimage in it but I got this compile error again:

/* com.apple.actool.errors */

: error: None of the input catalogs contained a matching launch image set named "LaunchImage".
