Xcode5 Code Coverage (from cmd-line for CI builds)

Question

How can I generate code coverage with Xcode 5 and iOS7?

Prior to upgrading I was getting code coverage just fine. Now I can\'t see any *.gcda files being produced.

Answer 1

We found that we had to add a bit of code to get the gcda files to flush from the system.

Code addition is to add extern void __gcov_flush(); to the top of your file and then call __gcov_flush(); just before the entire test suite exits.
