https://gist.github.com/966838 is a short bash script that meets Apple's requirement that CFBundleVersion should be a monotonically increased string.

Answer 2

You will need to install PlistBuddy to use this method.

The method that I use is to set the script as the last build phase, and make the changes on the target build directory. In other words:

BUILD_NUMBER=`git rev-parse --short HEAD`
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $BUILD_NUMBER" "${TARGET_BUILD_DIR}"/"${INFOPLIST_PATH}"

So in the repo the value should be a dummy value like 0, and it will get overwritten everytime. This does mean that the current build number will only be available after you build.
