A pair of scripts to help with basic parsing of LLVM code-coverage output data, as produced by Xcode 7. The `cov-exclusions.txt` file can be used to exclude files and globs from the output

code-coverage.sh

PRODUCT_NAME=${SCHEME}
WORKSPACE=${SCHEME}.xcworkspace
SOURCE_ROOT=./

ABSOLUTE_SOURCE_ROOT=$(cd $SOURCE_ROOT; pwd)
BUILD_SETTINGS=`xcodebuild -workspace ${WORKSPACE} -scheme ${SCHEME} -sdk iphonesimulator -showBuildSettings`

# Project Temp Root ends up with /Build/Intermediates/
PROJECT_TEMP_ROOT=$(echo "${BUILD_SETTINGS}" | grep -m1 PROJECT_TEMP_ROOT | cut -d= -f2 | xargs)

PROFDATA=$(find ${PROJECT_TEMP_ROOT} -name "Coverage.profdata")
BINARY=$(find ${PROJECT_TEMP_ROOT} -path "*${PRODUCT_NAME}.app/${PRODUCT_NAME}")

if [[ -z $PROFDATA ]]; then
	echo "ERROR: Unable to find Coverage.profdata. Be sure to execute tests before running this script."
	exit 1
fi

find ${ABSOLUTE_SOURCE_ROOT} -type f \( -name "*.h" -or -name "*.m" -or -name "*.swift" \) -print0 | \

print "Total lines: %d" % totalLines
print "Hit lines: %d" % (totalLines-missedLines)
print "Coverage average is: {0:.2%}".format(covAverage)

The code-coverage.sh file is derived from a script by @mgrebenets (see http://mgrebenets.github.io/mobile%20ci/2015/09/21/code-coverage-for-ios-xcode-7/)

Tools like this are seriously lacking in the community right now for llvm-cov, but this is exactly what I need/wanted for managing code coverage. Thank Brian!

Is there a particular reason you commented out the coverage output per file?
