Adobe-Runtime-Support iOS crash on SDK 51.1.3.8

Problem Description

Recently, we started experiencing iOS crashes 2–5 minutes after launching the game. The crashes occur randomly and not consistently, which makes it difficult to identify the root cause.

We're using dSYM files to symbolicate the crash logs, but not all symbols are resolved, so it's still challenging to pinpoint the issue.

The most recent change was upgrading the SDK from 50.2.4.5 to 51.1.3.8. After this upgrade, we noticed an increase in the crash rate in our Bugsnag tracker.

Which AIR SDK did you use? 51.1.3.8
Describe the affected environment: Android vs. iOS, all devices vs. just specific models. iOS only. There is no specific iOS version or device model; the issue occurs across a range of devices.
Can you reproduce it yourself, or did you get reports from other users? If so, how many users are affected (percentage)? We received crash reports from the Apple team. Additionally, we were able to reproduce it several times on one of our iPhones.

Steps to Reproduce

I am attaching the crash report. Based on this report, we haven't been able to identify a consistent set of steps or behaviors that trigger the crash.

Do you have any insights based on the crash log that could help us reproduce the issue?

Yes,i have the same problem,i use 51.2.1,did you solved this problem?

May 16 '25 03:05 zengqingyong

@udmv it's quite tricky to tell what's going on from your crash logs, particularly since the thread that crashed isn't a named one. Do you use Workers in your app, and is it possible to isolate any behaviour that might cause the issue? Or ideally, if it's quick to reproduce, would it be possible to try it with a variety of AIR SDK versions until you find the actual release that introduced the error?

Alternatively (and @zengqingyong you could do this bit) if you're able to use 51.2.1, there's a new entry you can add to your configuration file in ~/.airsdk/adt.cfg called IPASymbolFile, if you add a filename there you should then find that file is generated when you create the IPA package. If you can provide us with that file alongside the crash report/call stacks, we should be able to decipher them to find out the actual crash locations..

thanks

May 17 '25 05:05 ajwfrost

@ajwfrost i create new ipa use old crash report is ok?

May 19 '25 02:05 zengqingyong

@zengqingyong if nothing else has changed in the meantime then it might be that the details in the two IPA files are the same .. worth a try perhaps, if you send us the symbol details we can check and see whether the crash report can then be successfully deciphered. But if anything has changed (e.g. code, tool, or SDK) then I think it wouldn't be valid, and I'm not even 100% sure if rebuilding the same thing twice in a row would generate the same results...

thanks

May 19 '25 07:05 ajwfrost

@ajwfrost can you show me how to" add your configuration file in ~/.airsdk/adt.cfg called IPASymbolFile "

May 20 '25 08:05 zengqingyong

Assuming you're using macOS, you could open a terminal and just do something like

echo IPASymbolFile=ipa_syms.bin >> ~/.airsdk/adt.cfg

Note the double-greater-than symbol, to append to the end of the file.

Then when you build the IPA, you should also see the ipa_syms.bin file alongside it.

Thanks, that all worked out.. but it's a fairly fundamental problem it seems (the symbol where it crashed was a null pointer issue within a "write barrier" but that implies the object on which it's operating is null..). We can't actually see in the call stack what the value/variable was that's being used here:

Thread 0 Crashed:
0   Room Escape 50 rooms I              0x000000010054599c 0x10052c000 + 104860

When does this crash, is it just when you're starting up the application from scratch? As this seems to be when it's being deactivated e.g. put into the background or similar?

Also - is it possible to get your application descriptor file please (or maybe, the whole .ipa file would be more useful for us, if that's a possibility?). Upload link: https://transfer.harman.com/requests/u0RE4FHRPo82S83ygUKbpF

We found the cause of the two crashes I posted above. It was related to the Google User Messaging Platform (UMP) ANE we use. Apparently, the UMP SDK is not compatible with iOS 18.2, which comes with version 51.1.3.8 that we upgraded to recently.

@ajwfrost we're still seeing another similar crash affecting our users and are currently investigating it further. We plan to try version 51.2.1 with the IPASymbolFile configuration enabled to obtain the symbol file to share with you thanks

I can't reproduce it. It won't crash on my phone, but I can receive a lot of crashes in the background of Xcode. There weren't so many before until I was required to upgrade to ios 18. I have already uploaded the ipa

May 22 '25 07:05 zengqingyong

Because there were too many original ipa SWFS, I deleted a large number of SWFS to make the IPA a little smaller

May 22 '25 07:05 zengqingyong

@udmv How did you find that it was related to UMP?

Jun 12 '25 14:06 httpwebmedia

@udmv Did you find any solution about your bug? I still have a lot of crash named libobjc.A.dylib and I'm not able to find why. I talked to Andrew about it few months ago and we were not able to solve this problem. We tried with version 51.1.3.7 51.1.3.5 51.1.1.5 50.2.5.1 50.2.4.3 without any success.

@httpwebmedia @premiumsB I identified the root cause by removing the other ANEs from the project — the crash occurred only when UMP was included. In the end, I removed UMP from the project since it was no longer needed.

Jun 12 '25 15:06 udmv

@marchbold How can we fix that problem with Adverts and the one who want to use UMP?

I have this problem since several months and I can't update my bigger apps because I will get too many crashes VS the amount I got previously.

Jun 12 '25 15:06 premiumsB

@premiumsB if you're able to reproduce this yourself then could you do a build with 51.2.1.5 when you have something like IPASymbolFile=ipa_syms.bin in the adt.cfg file under ~/.airsdk, and then send us the IPS crash log from the device along with the ipa_syms.bin file that's generated alongside the IPA?

thanks

Jun 12 '25 15:06 ajwfrost

Hi @ajwfrost, we've attempted to work on this issue a few times by email before, but unfortunately I haven't been able to reproduce the error using the simulator. I can see the crashes in Xcode's Organizer under Crashes, but when I try to replicate them on the simulator with the same OS and device shown in the provided screenshot, the crashes don't occur.

Jun 12 '25 17:06 premiumsB

@premiumsB @udmv Have you tried packaging with the latest iOS SDK. Try setting your environment to use iOS SDK 18.4:

Jun 12 '25 22:06 marchbold

@marchbold I used 18.2 the last few months with adt.cfg here

Is it ok to use adt.cfg or I should use AIR SDK Manager for this?

Do you think that the version 18.4 will solve this problem with the adverts ANE?

Thank you for your anwser.

Jun 13 '25 12:06 premiumsB

@premiumsB Uncertain whether it will resolve your issue, but I believe Google are using 18.4 for Admob currently so you definitely should be using that with your app and is highly likely it could cause issues using an older version.

Jun 16 '25 23:06 marchbold

@marchbold Could I use the 18.5 to test or it's better to use 18.4 ?

Jun 18 '25 14:06 premiumsB

I would suggest 18.4 currently, but if you have 18.5 available can't hurt to try that first.

Jun 19 '25 04:06 marchbold

@marchbold After updating my mac OS to Sequoia 15.5 and Xcode 16.4 I tried to use 18.4 or even 18.5 but my info.plist doesn't show more than 18.2 even if I put the right path with adt.cfg or AIR SDK manager. How do you guys or everybody else use 18.4?

Jun 20 '25 13:06 premiumsB

@premiumsB I believe the value that AIR puts into Info.plist is still hard-coded to show whatever the AIR SDK itself was built with (where Harman is using 18.2), and it doesn't update the value in Info.plist to show what we use when packaging. I had asked about that a while back too (#3030). I don't know if there's any way to actually confirm that it's correctly using the iOS SDK you specify, unless maybe adt.log showing something?

Jun 20 '25 14:06 FliplineStudios

Yes, to clarify, if you're building on macOS then we use the Xcode and iPhoneOS SDK that you have installed there. The -platformsdk option confirms the SDK location but we recently made it default to pick up the iPhoneOS SDK that's identified via the xcrun build tools. On Windows, it uses the 'stubs' which can cause problems when running on older iOS versions, so there's also the option to use an iPhoneOS SDK on Windows via the LLVM linker (see release notes, configuration file details).

But the missing part (still) is that the entries that are put into Info.plist are just based on default constants that reflect the build environment that we have. This isn't ideal so we will look at having those reflecting the tools that were used, per the other ticket referenced above (I actually thought we'd done this but it looks like only a partial implementation in terms of using the details in the linker stage).

I don't know whether those Info.plist settings would affect the actual application behaviour though. If you check the build log and look for the "ld64 command line", it should have a -platform_version argument where you can see the platform, minimum SDK and build SDK values.

thanks

@marchbold I uploaded 2 of my apps with Adverts ANE V16.1.0, Xcode 16.4 targeting iPhoneOS SDK 18.5 and I still have that libobjc.A.dylib error over and over.

I have this error related to Adverts since the last 12 months and I would be really happy if I could find a solution.

Jun 26 '25 14:06 premiumsB

@premiumsB Can you replicate this issue on a real device at all? We haven't had any other reports of this with the Adverts extension.

Jun 26 '25 22:06 marchbold

@premiumsB I’m seeing the same errors. I can’t reproduce the issue on my end, but I’m working on getting AirDiagnostics set up.

Jun 30 '25 06:06 httpwebmedia

@ajwfrost I updated our app to the next SDK 51.2.1.5 and able to generate ipasyms.bin file. We are still getting reports from users about the crashes and they look like this below:
