Your app contains the Game Center entitlement, but it does not link against the GameKit framework.

Got 8 rejects from Apple.
Can't fix this issue:

Your app contains the Game Center entitlement, but it does not link against the GameKit framework.

Tried it on Unity 2018.1 and 2018.2

 

I have sent Bugs report to Unity very long time ago, about this issue. But cannot see it in issue tracker. Actually they don't care we can submit to appstore or not.

Rolling back to 2017 is the only solution. Forget 2018! They are not planning to solve this problem.

 

Nothing's stopping you from releasing outside of the Mac App Store. Plus you get 100% revenue. It's pretty easy to setup a basic PHP licensing system.

 

Wait a second- is this a problem particular to Unity 2018? And there's no viable solution at the moment?

 

Yes, it is only on 2018. And Unity don't think it is a bugs. It only not meet apple store requirement.

 

... and why we pay the subscription? I am sick of them adding garbage functionality to the point that nothing works! ... and they don't seems to care or be able to fix the problems.

If you're using GameCenter then you can just manually link the GameKit.framework
