I get this \"No image found at the path referenced under key \'CFBundleIcons\':\" error,
In my case the problem was the iOS target version. I was using iOS 9 as target and it appears that it was requiring icons that XCode wasn't showing in the Icons set when I created it. Changed target version to iOS 12 and it validated no problem. So, as usual, just a common iOS development problem. 13 years and their IDE still can't create the icons from an image, like Android Studio does.
