Xcode 16 crashes when attempting to view Build Settings for a target with Build Carbon Resources phase

This is both a heads up and an invitation for anyone affected by this to file feedback.

All betas of Xcode 16, up to beta 4, will crash when you attempt to view the Build Settings for any target that happens to have a Build Carbon Resources phase.

Any lucky soul who is still dealing with Rez, please make sure to file feedback to try and have this issue solved.

Have you filed for an FB number? Can you share the FB number on this post for other people who are having the same issue?

Don't forget to include the crash file on this post and FB, reproducible steps, and if possible, the project that is causing the issue. Once you open the bug report, please post the FB number here for my reference.

If you have any questions about filing a bug report, take a look at Bug Reporting: How and Why?

The issue has been filed as FB14474267. I just attached a crash report to it. It didn't occur to me that it was needed because luckily the steps to reproduce are very simple:

  • Create a new macOS application project, using Obj-C + Xib and skip Core Data.
  • Add a .r file to the project. Unless you do so, Xcode will leave the option to add the Build Carbon Resources Phase grayed out. The .r file can be empty.
  • Under the Build Phases section of your target, add a Build Carbon Resources phase.
  • Attempt to switch to the Build Settings pane for that same target, and observe the crash.

Thank you for looking at this so promptly!
