[Solved] iOS App crashes because of App Tracking

[skulamester]

Hi there,

My iOS app has been rejected, I got the followings from the Apple Review Team:

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.

Review device details:

• Device type: iPad
• OS version: iOS 14.7.1

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.

Could you guys have a look at the crash report? The problem is that I can’t reproduce the crash, I tried on several devices.

I was able to reproduce the crash on a friend’s Iphone XS with the following crash report:

crash.txt (109.3 KB)

Could you guys help me identify the cause of the crash? It will be very important as I can’t publish my app so. Thanks!

Hi there,

I did some more testing and got to the conclusion:

On iOS 14.6 everything worked great.

Updating the phone to iOS 14.7.1 the app crashes.

(iOS 14.7 was skipped)

Does anybody else facing the same issue?

[skulamester]

I have found something about the crash message:

When does a process get SIGABRT (signal 6)?

https://developer.apple.com/forums/thread/94817

[skulamester]

I have found the following line in the crash report:

It says a library crashed DUE_TO_PRIVACY_VIOLATION

What does that even mean?

[skulamester]

I know that this thread is 4 years old, but it might help identify the bug @Thunkable_Staff

__CRASHING_DUE_TO_PRIVACY_VIOLATION__

It says:

The __CRASHING_DUE_TO_PRIVACY_VIOLATION__ crash happens whenever there is a mandatory permission string missing on the app’s plist. Permissions level are changed by Apple with new iOS versions sometimes. So code that was working will start breaking with iOS updates that have new requirements for the plists.

It might has something to do with Touch ID/Face ID, as in the new iOS there are updates to that as well:

Well, not sure what I did, but I downloaded the app again and now everything works as expected, the app doesn’t crash.

I have filled these settings out, maybe that helped:

What does 'AdMob Settings' do on the App Settings tab?

Hi there, I can see this option on the App Settings tab, but didn’t find any information about this in the docs. What does this section do? Should I enter the details here? [image]

Thanks!

[skulamester]

I can confirm that this error was because of the Allow Apps to Request to Track property on the iPhones.

My AppId was missing in the AdMob Settings and having the Allow Apps to Request to Track property turned on, led to the error.

I had to enter the AppId and so the crash is gone.

Hi,
I have the same problem. The error pop up when any web viewer is opened.

I tried to set the tracking string empty or filled without any result.

I also have the privacy on apple account setted for “the app get data to control crash”.

Can you give me some advise?
Should I reset the privacy part on my account on Apple?
Thanks
