Auto-Version Xcode Projects Using Git Tags & Commits

autoVersion

# Sets the CFBundleShortVersionString of the Xcode project to the last git tag
# Sets the CFBundleVersion number to one of 3 options below

git=/usr/bin/git
fullVersion=`$git describe --dirty`

# Use the most recent git tag for the CFBundleShortVersionString
appVersion=`echo $fullVersion | cut -d '-' -f1 | sed 's/v//'`

# Use the most recent commit hash for CFBundleVersion
# buildNumber=`echo $fullVersion | cut -d '-' -f2`

# Use total of all commits and not just commits since last tag for CFBundleVersion
# buildNumber=`git rev-list --all | wc -l`

# Increment previous build number by 1 for CFBundleVersion
buildNumber=`/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "$INFOPLIST_FILE"`
let buildNumber=$buildNumber+1

/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"
/usr/libexec/PlistBuddy -c "Set :CFBundleShortVersionString $appVersion" "$INFOPLIST_FILE"
