Crash affecting iOS 15/15.1 on iPad

Our application is currently crashing in production for ipad running iOS 15/15.1 beta. If a developer builds that application directly to a device running iOS 15 or use simulator, the app will work as normal.

But we see a lot of crashes in the appstoreconnect analytics data. There were no reports of crashes from users. This bug cannot be reproduced on the device.

  • Hi everyone,

    Hope you are all well. Any update on this iOS 15 crashing issue? The App Store Connect Analytics is reporting a crazy amount crashes for our apps with iOS 15 users, but we and our testers have not been able to reproduce any crashes. This has been going on since last year and we have reached out to Apple several times about this with no response. We cannot run crash logs bc we cannot reproduce this crashing on any of our devices even though crashing is being reported in App Store Connect Analytics. Has anyone else experienced this with their apps and solved it?

    Looking forward to hearing back from you all so we can solve this for all developers experiencing it.

Hi Mikhail177,

We are experiencing this identical bug in our iPad only app. Have you managed to resolve it and if so how?

Thanks so much!

  • After update 15.1 on my iPhone , nothing works. Several crashes when in use on different apps, rebooting my device and battery life is like never existed. After watching like 6/7 videos with length about 1 minute each, battery drained 20% off. If I stream on YouTube, I need to stay plugged to power source. Fix this, is hard to have an apple product which cannot be used because of developers fault.

Hi everyone,

Hope you are all well. Any update on this iOS 15 crashing issue? We and our users still have not been able to reproduce any crashes in our app (we have several apps but only one is affected). Still App Store Connect Analytics is reporting a crazy amount crashes for iOS 15 users.

Looking forward to hearing back from you all.

Since me and my family updated to iOS 15.1 we’ve been having multiple crashes in a row and it’s keep happening in different apps. Please address the issue ASAP.

Thank you so much

Our application is currently crashing in production for ipad running iOS 15/15.1 beta.

Can someone post a full Apple crash report for this?

See Posting a Crash Report for hints on the best way to do this.

Having the same issue. A WebRTC app (publisher) did run up to 15.0.2. Today upgraded to 15.1. Crash after the browser asked for consent to use camera and mic. Happens on iPhone and iPad. Didn't happen on the iPad one hour earlier when 15.0.2 was on the iPad.

There is no indication for the reason of the crash in the browser console log (viewed from my MBP). I didn't check the crash dumps yet.

HI everyone,

Hope you are all well. Has anyone had any resolution/improvement on this iOS 15 crashing issue?

We are continuing to see huge numbers in crashes on our App Store Connect Analytics Data (for devices running iOS 15 +) but we and the testers we are in contact with are unable to reproduce these on any of our own devices or in the simulator. We have contacted Developer Support and are waiting to hear back.

Hello everyone!

We have maybe the same situation with our Ionic application. The issue appeared for only some of our users after updating to iOS 15.1.

For our application the issue is AppleID specific and not device specific. Resetting iPad (which had the issue) and setting it up with another AppleID fixed the issue. And when resetting the same device again and setting it up with the original AppleID, the issue came back.

Any help is appreciated. Thanks!

We are getting this crash, the app is working just fine in iOS14. Even in the simulator with iOS15, it's working. When it is connected to iPad/iPhone it instantly crashes, even tried to debug/get errors using the Exception breakpoint ( No errors )

I doubt this issue has anything to do with the other crashes being discussed on this thread. I’ve posted my analysis of your crash over on the thread you created for it.
