I have to update a game already live on App Store using Unity 5.2.3.
I have been getting a lot of il2cpp related errors due to which I cannot build anymore for iOS…this has been going on for 3 months now…have tried all Unity versions from 5.1.2 to 5.2.3…as you can imagine it has not been good for our business!
Have earlier posted this issue on Unity forums and posted Bug reports as well but still no solution has been found for this issue!
Am again posting these errors which come up at the time of building for iOS within Unity3D:
ERROR 1/4:

Really urgently need help on this issue, or else we may have to abandon this project, and make future games projects using other game engines!
