llvm-cov not working anymore on xcode 16

[mm44m6]

Hi. We´ve been using the llvm-cov step described here for a while in our projects but, with xcode 16, its not possible to reproduce this step any longer. It shows a message saying that coverage was not found.

(Edit path for privacy)

This is working perfectly fine with xcode 15.4 (we have a CI with the same env settings, the only thing being different is xcode (16.0 and 16.1) and macOS version).

clang output:
