Question

How to prepare app to be able for upgrading to the latest version available on AppStore

Answer 1

While setting the CFBundleVersion is something I always do, the displayed app version and and upgrading is handled in iTunes Connect and not something you actually "prepare" from a code perspective.

a) Logon to iTunes Connect.

b) Choose "Manage Your Applications"

c) Click the app you want to upgrade

d) Click "Add Version" - this is where you will supply the version number

e) Fill out the information as you would with any app.

Once approved the upgrade availability is handled by the end user's iTunes and alerts them that an upgrade is available. I have yet to use it, but I believe Apple has added the ability to choose when an approved app is released.
