How to Autogenerate App Version Number from GIT

Application needs a version number, naturally. It's publicly used to identify, which version customer is using (and reporting bugs about).

However there is a very important technical reason to take good care of version number: if you want to update application, the new version number must be bigger than the old one. Sounds easy, yet again...

Let's check the documentation:

Apple AppStore submit observations

Read docs a dozen times, but somehow missed these:

• Keywords can be max 100 characters - including spaces and commas
• Select "None" for first rating to get immediately 4+ rated
• CFBundleShortVersionString in the Info.plist file must be a period-separated list of at most three positive integers. You cannot use e.g. "1.0.0 (1)" format, except in ad hoc releases
• Large icon filename must end with .jpeg .jpg .tif .tiff .png. It's not about file format, but filename
  
• Upload screenshots in reverse order, the first shall be last
