Filed as FB24035409. The post description said that Xcode 26 and macOS 26 work well but macOS 27 and Xcode beta (so Xcode 27 beta) don't work. So the problem is only on the 27 train (macOS and Xcode), both beta 4 currently.

I've filed the bug now as FB24035409. No, the description says Xcode 26 with macOS 26 works correctly but macOS 27 with Xcode beta (so 27 beta 4) it is not working. Will appreciate a quick look at it.
