Crash on iOS v13 or above

Experienced this crash in ios13 or above os.

Seems like, it is related to Game Center.

Unity v2017.4.29f1
iOS 13

UnityAppController.mm line 171

We have the same issue

 

Having the same issue on 2018.4.6f1

Haven't seen anything in the newer LTS releases that suggest that it has been fixes there either.

This currently stands for the majority of our crashes on iOS. Is there a bugreport somewhere we can pile onto?

Seeing that this might be an issue with GameKit itself: https://forums.developer.apple.com/thread/125738

 

Still an issue on 2018.4.15f1

 

We're seeing this issue and using 2019.2.17 for users on iOS13, it's accounting for a lot of crashes coming from GKNotificationBannerViewController.

 

Same issue. Unity 2018.4.16f, iOS 13.3.1

 

Same issue, 2018.4.10f1

 

All, please submit this issue as bug reports via Unity Bug Reporter. Posting here is not likely going to get the most immediate attention from devs.

 

Seeing this as well, was there any resolution? On 2018.4.19f1

 

I have an unexpected and impossible to reproduce scenario. I have crashes on startup (app freezes) only in France (iOs 13). It is definitely not related to my app internationalization. I've tested the app in every possible way, including creating a French AppStore account, no crash, nothing. No where else in the world I have a similar scenario. I am using Unity 2018.4.24 (LTS).

The freezing is not reported on Crashlytics, AppStore, nowhere. So I have no clue of what it might be.

This is the AppStore page with the reviews, in France: https://apps.apple.com/fr/app/tacticalpad-coachs-whiteboard/id512949303

Thanks

 

This also happens on 2019.4 (LTS). Seems like Apple is admitting this is an iOS 13 issue that should be fixed with iOS 14 (https://forums.developer.apple.com/thread/125738), but this doesn't help for the time being. Are there any know workarounds (like providing the supported orientations directly from that call and not determining that via the buggy API)?

 

For me, so far, it is a random crash. I ask user to restart device, re-log in on AppStore. They usually return to me with : "I did nothing, tried again and the app opened this time". It is driving us crazy as we get crucified for something not on our side. I am trying to remove all possible plugins that may use GameCenter. But it is a shot in the dark.

 

For me it happens (randomly, but often) when the GameCenter notifications for achievements are to be shown. And of course it is all blamed on my app, and people might never give you a rating when all works nicely, but they are quick with 1 star when the app crashes just once

 

Yep, same for us. But in our case we do not use GameCenter (at least we don't call anything, any plugin might add its sdk(like Prime 31)) and we have this bizarre thing that happens almost only in France. Anyway, the blame will always be of the developers, try to convince someone that spent $$ with an Apple device that his device or the Apple services are buggy, they get mad at you hehe. Good luck with the issue, fingers crossed for the iOs updates.

 

And you're not getting any crashlogs in Xcode Organizer?

 

No. The app hangs on the launch screen. It may be a different issue than this one. As it is not crashing, no info on Crashlytics or XCode. Not reproducible, even if set to French AppStore, with app and device in French. Unfortunately no idea. Not sure if I hope it is this same issue or a different one.

The only thing that we know (from the reviews on AppStore and the emails we received from users) is that it started from nowhere (not after an update from us) but it started in 2020. Here is the review page in France (nowhere else we have it): https://apps.apple.com/fr/app/tacticalpad-coachs-whiteboard/id512949303#see-all/reviews
