I'm seeing this in 16.3 as well. Possibly due to ancient .xcframeworks injected by Carthage. An older version of Xcode should be able to view the offending .profraw files and at least dump some info to show what framework it came from. Now on Sequoia, so going back far enough is no longer an option. Boo!

I've opened Feedback: FB17628220 for this. There appears to be something wrong with the later 18.3, .4 SDKs as the profraw file that is pulled from the Simulator is just in the wrong format.

FWIW, also tested in Xcode 16.4 (iOS 18.5) and still no go.
