Validation fails with *.mlmodel file.

I'm updating a machine learning iOS app. When I archive and validate the app with a ***.mlmodel file, the validation fails with following error message.

"App Store Connect Operation Error"
"Unable to process app at this time due to a general error"

I found that if I un-check the *.mlmodel file from the target membership, it gets successfully validated.

Is there anything I missed? Or is there any workaround?

XCode version 12.5
Create ML Version 2.0


I found a tool "Transporter" provided by apple, which can validate and upload ipa files to the app store. I tried this tool instead of XCode. Then, my iPhone app, Chichibu Unkai Watcher was successfully validated, uploaded and approved.
As for macOS version, I could not create an ipa file. So, I uploaded without validation, but it was approved.
So, I'm thinking this is a XCode bug at this moment.


I wasted half a day on the same issue. My solution is below. 1.Make ipa file by Xcode. But you choose Product - Achive - Distribute App(Not Select Validation App), and choose App Store Connect - Export. 2.Upload ipa file by "Transporter" You are able to Validation and Delivery.

Big Sur ver11.1 Xcode 12.4 Transporter Ver1.2.1

Validation fails with *.mlmodel file.
