iOS Question My First iOS app fails review - crashed

My first iOS app is crashing during the Apple review process. I have never had this problem. Apparently, it crashes immediately for Apple. I have tested in debug and installed the release version on my test iPhone and it always works for me, running both the debug version and the release version. I am using B4i v6.80

I am at a loss here - the crash report from Apple does not tell me anything - I do not know what to look for. I have attached the crash report to this posting. They had 6 crash logs for me and all appeared the same and were created about 1 minute apart each.

If anyone can look at the attached crash log and point me in the right direction I will be forever grateful.

Below is a synopsis of what Apple says:

Guideline 2.1 - Performance - App Completeness

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 address the crash in your app, follow these steps:

1. Fully symbolicate the crash report. See Adding Identifiable Symbol Names to a Crash Report for an explanation of the symbolication process.
2. Match the crash report to a common pattern. Based on the pattern, take specific actions to further investigate the crash. See Identifying the Cause of Common Crashes.
3. Test your app on a device to ensure that it now runs as expected.
4. Once you’ve addressed the crash, create and submit a new build to the App Store for review.

After doing a little research I see I need to symbolicate the crash log. I do not have a mac and no access to XCode, so how can I symbolicate my crash log to see what is going on in more detail? Unfortunately I could not find any online services to do this, if they even exist.

Have you tested it in release mode after you previously uninstalled the app?
Have you tested it in airplane mode?

Yes - I have done several clean installs in release mode and have tested each in airplane mode. All work flawlessly for me. And the Apple Review people verified the app crashes on load. Because I have the crash logs from Apple, I am trying to figure out a way to symbolicate the crash logs without having access to xcode. Any suggestions as to how to do this?

Maybe you should have some beta testers to test the app before launch to production.

I have crash reporting added to my app but the app crashes on load so any beta testers would never get the chance to send me the crash report. That is assuming the app would crash for the beta tester - the app works perfectly for me in both debug and release modes, with or without airplane mode turned off. I am testing via hosted builder on an iPhone 8 running iOS v14.3

Yes, this is my first app and I would very much like you to help me out here. I could probably figure this out myself if I had a way to symbolicate the crash report but I do not. I will send you the files via email. Thanks much.

This line:

[b4i_lead_remove_records _deleteleads:::::::] (in CommPayPro) + 5928

is a code module that is manually triggered by the user well after the app has been logged into. Because Apple is reporting the app crashes on launch, this does not make sense at all. I am sure I sent you the correct crash report. But I have subscribed to MacinCloud.com so I now have access to a mac and xcode so I can symbolicate the logs myself.

Question: All 6 crashes during the review happended on Thread 0. I assume this is the launch of the app, correct? Typically, when does Thread 0 terminate? When will another thread be started, or is the entire running of the app happening on a single thread?

Are you 100% sure that the IPA is the same one as the one submitted to Apple?

thread-0 = main thread. All your code runs on this thread.

No - I sent you a regenerated IPA but nothing had changed in the app - does that make a difference?

I develope and test my app on an iPhone 8 running ios 14.3

per the crash reports Apple used - "Hardware Model iPhone11,8" and "OS Version: iPhone OS 14.3 (18C66)" so it looks like they used the same OS I am testing on and also used an iPhone11 and iPhone8 for testing.

I believe I have the same archive I used for the Apple upload if you would like to look at it for me. I am spending a lot of time figuring out how to use XCode to make the crash logs meaningful. Never used a MAC before and am running it via RDP

I have no doubt the app crashed for Apple and once I can get the 6 crash logs symbolicated I should be able to figure out what the problem is. I have been using B4A for 8 years and find publishing an Android app to be much less stressful than being in the Apple ecosphere, lol.

I have another Archive other than the one I sent you and I think it is the same Archive from my uploaded app.
