[Bug]: iOS crash on startup

[esentis]

What happened?

Hello,

Our app encountered an issue during the iOS review process, where it appears to hang on the splash screen during startup. According to the provided crash log, the crash seems related to OneSignal’s clearBadgeCount method, which may be called internally.

Thank you for your assistance.

The reviewer's device :

Device type: iPhone 13 mini
OS version: iOS 18.1

Steps to reproduce?

Unfortunately, we haven’t been able to reproduce this issue on our own devices, so we’re unsure of the specific conditions that trigger it. Any guidance on resolving or debugging this would be greatly appreciated.

What did you expect to happen?

Same here. Did you manage to fix it?

[nebis-software]

I had a similar one, see here: https://github.com/OneSignal/OneSignal-Flutter-SDK/issues/912#issuecomment-2481244849 not sure it is the same

[zafarivaev]

Not sure the above fixes the problem, my guess is that we can disable badge clearing logic by adding OneSignal_disable_badge_clearing: true to Info.plist. I will try to send another submission and see if Apple approves it

https://documentation.onesignal.com/docs/badges

[zafarivaev]

Apple approved this submission, so looks like it's a valid fix.

@zafarivaev Interesting, I'll do this aswell and close the issue if it'll be resolved.
