This started happening after iOS 13 was release. I started seeing a lot of crashes in productions with this in my fabric logs.

Steps To Reproduce

  1. I am not able to reproduce this but similar issue was found in 0.59.5 in iOS so we upgraded to 0.59.10 thinking it will fix the issue but it is still happening in production.

I cannot updated to latest RN because of Android X changes.

It looks like you are using an older version of React Native. Please update to the latest release, v0.61 and verify if the issue still exists.

The "Resolution: Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

@oleksandr-dziuban @nikechanhk - we're experiencing a highly similar issue and we're on RN 0.61.4 - we get it both on iOS 12 and 13.

still having the same issue with 13.2 iOS. Was anyone able to reproduce this on a simulator?

nidongara picture nidongara on 11 Nov 2019

@kennym does it crash always on load?

nidongara picture nidongara on 15 Nov 2019

@nidongara yes, the crash always immediately happens after app load.

kennym picture kennym on 15 Nov 2019

@kennym for me it happens 1 out out 20 times. I am not able to reproduce this in my simulator or test devices.

nidongara picture nidongara on 15 Nov 2019

@nidongara it only happens for us in release mode

kennym picture kennym on 15 Nov 2019

I tried release mode but it doesn't crash. @kennym Did you guys figure out a work around?

@nidongara Would you try editing the issue description to indicate a current version of React Native, based on the reports in comments? Here's the instructions the bot gave (they're hidden behind a fold):

The "Resolution: Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

It looks like nobody at Facebook has noticed this issue -- I suspect they completely ignore issues when they have that label attached.

At this point it's no longer helpful to add more reports of seeing the issue on RN v0.59. I think it's no longer helpful to report seeing it even on RN v0.61, now that v0.62 is out.

What would be very helpful is a report for v0.62, the latest version. (Or better yet, the v0.63 release candidate!)

If you're looking at this thread because you're seeing this issue, and your app is using v0.62 (or later): please add a comment with details like @luatnd's https://github.com/facebook/react-native/issues/26985#issuecomment-596986763 :smile:

Until then the developers of React Native will effectively assume the issue was fixed in v0.62, and ignore it to focus on the many other things on their to-do list. That's what, as I read it, the label "Needs: Verify on Latest Version" means.

And if you're reading this in the future, and someone has already reported it on v0.62 and a newer release is out (but this thread doesn't show a fix yet): same thing applies, just increment all the version numbers in this comment.

For us, this crash didn't happen until the release where we enabled RAM bundling.

@dougcoburn
Hello, how did you reproduce it? And how to prove that enabled RAM bundling setting works.

Struggle is real! i can still reproduce it with versions 62.2

I was able to get this resolved by rewriting our AppDelagate.m and AppDelagate.h from scratch.

Used the react native upgrade helper to see what those files looks like for a new project, copied that in, and the went though all our native libs that had modified those files (RNN, firebase, and app auth) to set them back up.

By the time that I finished, there was about a 30 line difference. At some point we did a bad upgrade in the past or their initialization had changed, and it finally started crashing when iOS 13 came out.

@aklinker1 do you mind sharing your AppDelegate.m before and after?

asafda picture asafda on 10 Aug 2020

Sure thing! This is before and after the fixes for RN 60, but this also worked when we did similar re-writes for RN 62. The main thing to notice is how different the RNN and Firebase setups are.

I would also recommend making these changes in XCode, you'll get errors and warnings in real time.
