Xcode Install: Predictive Code Completion Model Failed

Does anyone know a workaround for this issue during downloads?

Predictive Code Completion Model

Failed -- There was an error processing the asset.

I have tried installing the latest Xcode 16.1 and 16.2beta2, and both fail the same way. It has not been resolved for 2 days, so I don't think it is temporary server issue. I also tried 2 different network providers and a hotspot as related posts with different details mentioned.

Details:

  • The operation couldn’t be completed. (IDELanguageModelKit.IDEModelDownloadAdapter.(unknown context at $13003dd20).DownloadError error 3.)

  • The operation couldn’t be completed. (IDELanguageModelKit.IDEModelDownloadAdapter.(unknown context at $1101b5d90).DownloadError error 3.)

After reading a comment where they came back a day later and it just worked, I tried rebooting and launching 16.1 it started downloading and now also works in beta.

Working Steps:

  • Install both release and beta Xcodes
    • Will see errors for both
  • Reboot
  • Launch Xcode 16.1
    • Started downloading successfully
  • Close Xcode 16.1
  • Launch Xcode 16.2beta2
    • Shows it is already installed
