I created a thread about it yesterday, but it looks like UIMarkupTextPrintFormatter got caught up in this as well.

As a followup - this appears to only be true for macOS Catalyst apps. It looks like UIPrintInteractionController and UIPrintInfo also got sucked into this mess as well? Are these truly not allowed for macOS Catalyst now?

I was in the process of setting up a new automated build this morning and started getting this error message too. Same scenario - I'm trying to upload both an iPadOS and Catalyst version of my app with the same build numbers. I'm using the xcrun altool command line tools to upload my builds. *** Error: Error uploading '<My App>'. *** Error: The bundle version, 1, must be a higher than the previously uploaded version. Duplicate bundle version. (-19210)  {     NSLocalizedDescription = "The bundle version, 1, must be a higher than the previously uploaded version.";     NSLocalizedFailureReason = "Duplicate bundle version.";     PreviousBundleVersion = 1; }
