Run Script Build Phase for Xcode to automatically increase CFBundleVersion

xcode-build-version-number.sh

#!/bin/bash

# Run Script Build Phase for Xcode to automatically increase the CFBundleVersion value
# on your target's Info.plist using a 'yymmddHHMMSS' style timestamp. 
# Also, sets a custom key with the current git commit hash (GIT_COMMIT_HASH)
#
# This script works by modifying the target copy of your Info.plist file, so that it won't
# change your original Info.plist which is under version control. It does, however, use
# the original file to read the initial CFBundleVersion value to which the timestamp
# for the current date/time is appended.
#
# Inspired by the work of Tommy Goode (@airdrummingfool)
# http://tgoode.com/2014/06/05/sensible-way-increment-bundle-version-cfbundleversion-xcode/

# Usage:
#
# Under your project properties choose the adequate target, select Build Phases and click
# the '+' button, then 'New Run Script Phase'. Paste the contents below and make sure
# it's set AFTER the 'Copy Bundle Resources' phase (you can reorder by dragging).
