Sorry for the very late update. As far as I understood running llvm-cov multiple times would not work for us. We are trying to extract coverage from UI tests (integration tests) which are run on our iOS application. At compile time the app, to improve build times, is linked against prebuilt frameworks of our modules. We need to extract a single coverage result which covers all the source code of our app along with the source code of our separate prebuilt modules. Hope this makes sense.
