Fixing the Invalid CFBundleVersionShortString in RubyMotion

August 27, 2012

If you’ve gotten as far as submitting an app through xCode, getting stuck with this error message can be confusing.

This bundle is invalid. The key CFBundleVersionShortString in the Info.plist file must contain a higher version than that of the previously uploaded version.

In a RubyMotion project, the Info.plist file is derived from the configuration object exposed in the Rakefile file. For example, the CFBundleShortVersionString variable in Info.plist is derived from the name variable in the Rakefile. Most of the time, the configuration object will let you control the necessary settings of his project.

All you have to do is set the value for CFBundleShortVersionString in your Rakefile file to what you’ve set your app.version to:

Motion::Project::App.setup do |app|
  # ...
  app.version = '1.1'
  app.info_plist['CFBundleShortVersionString'] = '1.1'

NOTE: Also, as of June 1, 2012, RubyMotion informed us that the app.info_plist call will cause all following calls in your Rakefile to be ignored, so make sure you put this at the very end of your Rakefile file. Known issue, I’m sure they’ll get that fixed.
