“ITMS-90338”

We have several Mac Catalyst apps that use UIPrintInfo and UIPrintInteractionController to support printing. Both of these classes are marked as available on Mac Catalyst 13.1 in the documentation and we do not receive any errors or warnings using them in our app. We have successfully uploaded to App Store Connect recently with apps that use those classes, but now are receiving error messages from App Store Connect complaining that the use of these classes is non-public API and receive the ITMS-90338 error, even though no code has changed. Is this an issue on the validation side, or are these classes no longer supported on Mac Catalyst? Thanks in advance for any help!

Greetings, Trying to submit another build of my app to TestFlight, and while the first submission a few weeks ago was accepted and successfully passed the first TestFlight review for external testing, subsequent builds are now failing with that error either while uploading the app, or after it's uploaded and its state is Processing. This is frustrating because without knowing the name of the private API being claimed that the app is using I have no clue as to where to even look. While I know that I'm not using any private Apple APIs in the app, I do link with 12 pods, so perhaps one of those pods is now using an Apple private API? The last action I remember taking after first successful submission, is to ensure that I could debug on an iOS simulator, since I'm on an M1 Mac and no longer on an Intel mac. Maybe that has something to do with it? Aside from opening a TSI, any suggestion as to how I can find the culprit? Or if it's a corrupted binary, how do I find out why or what is corrupted? If need be I will p

When I try to upload to apple store connect from XCODE, I get the following error. the app contains one or more corrupted binaries. rebuild the app and resubmit. with error code state_error.validation_error.10 for id ***** This error started appearing suddenly today. I have not made any major changes since yesterday. It had never appeared before. I get the same error when I try to re-upload other app builds that I was able to upload before. state_error.validation_error.10 error code does not show up at all when I search google. Also When I upload an exported build via Transporter, I get an email with the error ITMS-90338: Non-public API usage. I have tried restarting the MAC, clean build of XCODE, etc., but to no avail. Can someone please help me? (My environment is XCODE13 and Unity2020.)

ITMS-90338: Non-public API usage - The app contains one or more corrupted binaries. Rebuild the app and resubmit.. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed.

For further information, visit the Technical Support Information at http://developer.apple.com/support/technical/ There weren't any third party SDK or Unity updates since the last version. And the last version(20220723) is OK, how can I identify the source of the problem? I'm using Unity 2019.4.17f1c1 with MacOS 12.4 and XCode 13.4.1.
