Quinn, thanks for the update on the status of a fix. However, I'd like to suggest one other scenario be tested and that is: Install macOS 26.5 Update to macOS 26.6b3 Install Xcode 27 beta This would help to show that the act of installing Xcode 27 beta doesn't break something, like it did when installed on macOS 26.5.

I've filed a bug report. In it, I included an Xcode project that will build a test app that demonstrates the issue. The feedback number of the bug report is, FB19929918.
