Automated Bundle Version

Posted on December 7, 2015

Lately I've been using a script to set my apps’ bundle version.

Add a new Run Script build phase. Change the shell to:

/usr/bin/env ruby

Put the following in the source area (right under the shell field):

git = `sh /etc/profile; which git`.chomp
app_build = `#{git} rev-list HEAD --count`.chomp.to_i
`/usr/libexec/PlistBuddy -c "Set :CFBundleVersion #{app_build}" "${TARGET_BUILD_DIR}/${INFOPLIST_PATH}"`
puts "Updated #{ENV['TARGET_BUILD_DIR']}/#{ENV['INFOPLIST_PATH']}"

This will automatically set your CFBundleVersion to the number of commits in your current branch. TestFlight requires a different bundle version for each build so this automates away having to remember to mess with that.

Enjoy.

Update 2020-04-01: If you are using the new Xcode Build System, you need to add $(TARGET_BUILD_DIR)/$(INFOPLIST_PATH) as an one of the "Input Files" for this to work.
