Unable to deploy my react native app to app store (iOS)

Question

I'm trying to deploy my app to the apple app store, the app was created in react native, I sent my app to be reviewed with apple, it was rejected, their response was:

Guideline 2.1 - Performance - App Completenes.

We were unable to review your app as it crashed on launch. We have attached detailed crash logs to help troubleshoot this issue.

Next Steps

To resolve this issue, please revise your app and test it on a device to ensure it will launch without crashing.

Resources

For information on how to symbolicate and read a crash log, please review Tech Note TN2151 Understanding and Analyzing Application Crash Reports.

The thing is that I have tested my app with several devices and several versions of iOS and I don't have this problem, not even a similar one. Please, I would like to know what could be the problem and how to solve it if possible, thanks in advance. The crash log is:

Answer 1

Probability is because you didn't test your app in release mode. Check https://stackoverflow.com/a/18038359/2407880

Answer 2

It seems you already fixed the question. I am writing my approach for the someone who has similar situation.

1. You have to read crash report very carefully.

In the crash report in your question, there are many threads and which one is crashed. In this case com.facebook.react.AsyncLocalStorageQueue was the starting point to solve this problem. You may check the code using AsyncStorage.

2. React Native is running in JavaScriptCore.

In the threads which are containing JavasScriptCore, there could be clues which codes were running at the crash moment. In thread 8 in your crash report, there is pretty depth JavaScriptCore call stack. But this call stack is not symbolicated yet. If you keep the archives in your mac, then you can drag your crash report into the Xcode's crash log view. You can follow the Apple's tech notes: https://developer.apple.com/library/content/technotes/tn2151/_index.html

After symbolicating, you can presume what's happening in your RN app at crash time.

Good luck!
