Build number is not unique

[kitallis]

Build numbers are not unique. A combination of build number + version name, however is.

Did some experiments on this for App Store. Here are the results.

TL;DR:

• version name should always be greater than the last production release
• version code and version name combination should be unique
• version code does not have constraint on being higher than previous value

Here is more data on this:
