Not able to connect iPad with Xcode

Thanks for the post.

It looks like you're encountering an issue with connecting your iPad 10th gen to Xcode due to a problem with Device Development Interfaces (DDI).

I would recommend to check this post: https://developer.apple.com/forums/thread/761235?answerId=800905022#800905022

Where you can see you can force the tools to download and check the connection to your devices as well as how to gather the information to see the issue you are having.

First run: xcrun devicectl manage ddis update

Still does not work, gather the information using

xcrun devicectl list preferredDDI
xcrun devicectl device info ddiServices --device <Device Identifier>

• Understanding DDI: The error message indicates that the system is unable to find a suitable DDI for your iPad, which is crucial for establishing a connection between the device and Xcode. DDIs are responsible for handling the low-level communication between the iOS device and development environments like Xcode.

• Check Xcode Command Line Tools:

  • Ensure that your Xcode Command Line Tools are up to date. You can do this by running: bash

xcode-select --install



• Run devicectl Command:

  • Execute the command mentioned in the error to list preferred DDIs: bash
devicectl list preferredDDI

  • This will provide more insight into which DDIs are available and why one might not be selectable.

• Restart and Reconnect:

  • Restart your Mac and iPad. Then, try reconnecting the iPad to your Mac using a high-quality USB cable, ensuring the cable and port are functioning correctly. Try a different cable or port if possible.

• Reinstall Xcode

Please let me know the results. Thanks

I ran the command "xcrun devicectl list devices" and it shows "connected (no DDI)". Also, tried the other suggested commands, please see the result below.

Command: xcrun devicectl list preferredDDI
Result: Host CoreDevice version: 443.19 WARNING: No usable DDI found for the iOS platform (The DDI's CoreDevice content is too old.). Best (unusable) DDI found is: • hostDDI: file:///Library/Developer/DeveloperDiskImages/iOS_DDI.dmg

Command: xcrun devicectl device info ddiServices --device <Device Identifier>
Result: ERROR: Failed to find a DDI that can be used to enable DDI services on the device. Usually this means the best DDI we could find for a platform did not have compatible CoreDevice content. Run 'devicectl list preferredDDI' from the command line to get more details on why no valid DDI can be found. (com.apple.dt.CoreDeviceError error 12001 (0x2EE1))

I am still not able to connect. Kindly let me know if there is any way to fix this issue.
