geko bump
geko bump is an alternative to agvtool (Apple generic version tool) that supports .xcconfig settings.
To use simply pass a path to .xcodeproj file and provide optional version and/or build number.
Example:
geko bump ~/projects/project/Main.xcodeproj --build-number 123 --version 1.2.3
This command will find plist file INFOPLIST_FILE associated with each native target in Main.xcodeproj and update fields CFBunldeVersion and CFBundleShortVersionString to specified version and build number.
