macOS 15 beta 3 - Xcode-beta - Loading a plug-in failed

I am trying to run the latest Xcode-beta in a beta 3 VM on beta 3.

After expanding the XIB I get the error "Loading a plug-in failed." It appears to work correctly directly on the running macOS 15.0 Beta (24A5289g)

Has anybody had any luck with this?

Expanding Xcode on the native platform and then copying it to the VM ddid not solve the issue.

Hello,

This is a known issue, documented in the Xcode 16 beta 3 Release Notes.

Xcode will fail to launch for some users. Users who have not installed Xcode 16 beta or Xcode 16 beta 2 will see a “Loading a plug-in failed” alert. (131066390)

You can either install Xcode 16 beta 2 prior to installing the beta 3, or you can open the terminal and select Xcode 16 beta 3 with

xcode-select -s $PATH

Then run

xcodebuild -runFirstLaunch 

and Xcode should be able to launch.

Let us know if that doesn't resolve the issue for you!
