both ARFoundation and ARKit XR Plugin have already update to 4.2.6 , also the same error

If you haven't already, try cleaning the Xcode project that Unity generated before you did the update. Unity might be keeping some of the files from previous build which could interfere with the current build.

I also recommend using version 4.2.7 which is the latest patch. Version 4.2.6 had couple of critical issues which we fixed in 4.2.7 patch. You will need to use Xcode 14.0 or higher with 4.2.7.

I had the same problem when XCode suddenly upgraded itself. This XCode error message appeared when trying to do iOS Unity AR builds to my iPhone. It was finally solved when I upgraded my Unity Editor to the most current version, 2021.3.16f1.

Thanks for the tip, @loreleip.

The native symbol _UnityARKit_Camera_GetTextureReleaseCallbackHandle existed in AR Foundation 4.2.6 and was removed in 4.2.7. After updating to the new AR Foundation and ARKit 4.2.7 patches, remove the previous Unity generated Xcode project to avoid this issue. Updating the Unity Editor might have just cleaned/overwritten the cache of compiled libraries resolving the problem.
