@SwiftBeginner2026 Thanks for the detailed summary. Given the checks you have already completed, my next recommendation would be to collect a CoreDevice diagnostic archive while the problem is occurring.
Apple’s Developer Tools team has specifically recommended this for devices missing from Device Hub:
Device Hub issue — Apple engineer’s diagnostic recommendation
There is also a similar report where Finder and Apple Configurator recognized the devices but Xcode did not. In that thread, DTS recommended enabling CoreDevice logging before collecting the diagnostics:
Xcode not seeing devices — DTS response
Here is the specific next step I would suggest:
Open Apple’s Profiles and Logs page and find CoreDevice Framework for iOS/iPadOS. Follow the linked instructions to enable the relevant logging on your iPhone. The page also provides a separate CoreDevice entry for macOS.
With logging enabled, reproduce the problem: connect the unlocked iPhone and open Device Hub so that it shows “No Physical Devices.” Note the approximate time of this attempt.
Keep the iPhone connected and run this in Terminal:
xcrun devicectl diagnose
Save the diagnostic archive at the location reported by the command. If collection reports errors, keep those exact messages and any archive it manages to generate.
Submit a report through Feedback Assistant, attaching the archive, your troubleshooting summary, the exact macOS/Xcode/iOS versions and build numbers, and a link to this thread. Then post the Feedback ID here so the Apple engineer already participating can refer to it.
Please attach the full diagnostic archive to Feedback Assistant; a Feedback ID and a redacted error excerpt are sufficient to share publicly here.
This is a diagnostic collection step and does not erase your iPhone. I cannot confirm a particular failing service or a known Xcode 27.1 bug from the two status fields alone, but these diagnostics give Apple a concrete basis for investigating the discovery and pairing failure.
