Xcode 15 Error mounting image — Disk image transfer is already in progress

Question

I recently updated to Xcode 15 Beta 7, and I'm having this error when running the app to my device (iOS 17 beta 7). It says that an existing disk image transfer is already in progress.

Waiting to reconnect to my iPhone 13 Pro

Previous preparation error: The developer disk image could not be mounted on this device.. Error mounting image: 0xe8000124 (kAMDMobileImageMounterExistingTransferInProgress : An existing disk image transfer is already in progress.)

It's a beta. You are a beta tester for Apple. File a bug report with Apple. – Clientele

Answer 1

To reset Trusted Computers:

• Go to Phone Settings > Developer > Clear Trusted Computers.
• Now install the app again and you'll need to click 'trust' on the dialog again.

Wait until cache symbols are completed. Here is what you will see.

And it worked for me. Hope it helps. Thanks

In addition to this, I had to restart the iPhone (and Xcode just in case), then it worked – Brine

Answer 4

I ran into this today as well. I was running Xcode 15 beta 5 and updated to 8. That didn't do the trick, so I restarted my iPhone running beta 8. That seemed to do it! Might have been a combination of both or just the phone restart. Hope it works for you.

Answer 7

I faced the same problem after updating from Xcode 15.3 to 15.4 (beta1). Going back to the previous version didn't work.

I solved this problem with the method below.

1. Unpaire the all device in Xcode
2. Delete all Xcode
3. Delete /Library/Developer
4. Delete ~/Library/Developer
5. Reinstall Xcode

Env: Xcode 15.3, macOS Sonoma 14.4.1(23E224), iOS 17.4.1
