ITunes Connect Version
ITunes Connect Version — The version number shown on the App Store; This must be a clean version number, e.g. 1.0.1
CFBundleVersion
CFBundleVersion does not have to be a real version number. It could be something like 12345 or 1.2.3 (Build 12345AB). This is shown, for example, in the "About" window for Mac OS X applications and often has more "Builds a Number" than a "Version Number".
CFBundleShortVersionString
CFBundleShortVersionString is used as the real version number. This should be the string used for the version in iTunes Connect.
