If you can reproduce the crash, can you please submit a bug-report following the advice given in this document? This allows Unity Technologies to repair their software and we, the customers, benefit from a more stable engine.
I would love to - unfortunately, the issue only occurs on builds deployed to iPhone / iPad. Since I assemble those on a Mac Mini (which is slow as hell), it takes me around 20 minutes to get a build from my PC to my test device (and even then I’m not terribly good with Xcode-specific debugging tools).
I’ll see what I can figure out, but I’m afraid the best I can do here are screenshots (which are the same as what the other user has shared).
Unfortunately, screenshots will not enable Unity to fix the issue. They most likely need a project to reproduce the issue and test their fix against. From past experience, every crash-bug I reported without a project attached, didn’t lead to a bug fix. Attaching a project on the other hand, did lead to a fix multiple times.
If you (constantly) run into this crash with your project, sharing the project with Unity, along with a step-by-step list what to do to make it crash (be it as simple as “Deploy to iPhone 6 and start”), is probably the most helpful thing you can do to allow Unity to repair their engine.
In order for Unity Technologies to debug and test a potential fix, they need a project where said error can be reproduced and tested against.
Therefore the answer would be “Yes, UT needs a bug-report with a project to reproduce the issue to be able to reproduce the error, fix it and test their fix against”. Even if someone else already submitted a report for the same issue, it’s often from advantage if another person submit one too, so UT has more than one project to test/reproduce the issue. The simpler the project where that error can be reproduced, the better.
Here is a page how UT wants us to submit bug-reports:
I’m not sure if it will help but here are some screenshot that I have take with the issue:
Debug:
In release appears like this:
It’s appears to happened randomly but especially after show Admob Ads (I have integrated Admob and Unity Ads with mediation). Sorry to don’t be able to help more.
If nobody submitted a bug-report, Unity is not going to fix the issue. Please submit a bug-report if you didn’t do that yet. https://discussions.unity.com/t/686800/6
I agree with this to a degree. But in the final, if Unity can’t have eyes on these problems themselves as well, then it will also be to their detriment. The original post was more than enough for a developer familiar with that code base to have a solid idea about what is going wrong.
