Download container SwifData from XCODE

Hi, I'm trying to download the container with SwifData of my App from the iPhone device connect through a cable to my MAC, for debug purpose. I get an error

System Information

macOS Version 26.0.1 (Build 25A362) Xcode 26.0.1 (24229) (Build 17A400) Timestamp: 2025-10-30T11:00:38+01:00

Was the app installed in a different way (like by App Store downloading vs. with Xcode) or with a different version of Xcode?

I've tried installing my app with Xcode 26.1 beta and then downloading the app container. The error doesn't happen, and I get the file successfully.

When trying to download the container of an app that was installed before (with an older Xcode version, I do get a similar error, but the file is still transferred and the data is there. Do you see the same?

Best,
