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.

With the information from here I was able to craft this version which is the least invasive I could think of. Just add to your unit tests and run the tests as normal. The ZZZ ensures it is the last run suite of tests.

I had to ensure I added the GCC_GENERATE_TEST_COVERAGE_FILES and GCC_GENERATE_TEST_COVERAGE_FILES compiler flags to my test unit target too to get the coverage out.

#import 

@interface ZZZCodeCoverageFixForUnitTests : SenTestCase

@end

@implementation ZZZCodeCoverageFixForUnitTests

// This must run last

extern void __gcov_flush();

-(void)testThatIsntReallyATest
{
    NSLog(@"FLUSHING GCOV FILES");

    __gcov_flush();
}


@end

Edit, or another approach by Jasper:

I stripped the VATestObserver from the other answer down to this:

@interface VATestObserver : SenTestLog
@end

@implementation VATestObserver

extern void __gcov_flush(void);

- (void)applicationWillTerminate:(UIApplication*)application
{
   __gcov_flush();
  [super applicationWillTerminate:application];
}

@end
