    Hello @Vuforia-Strasza! We're facing an urgent issue that is killing our app crash free metrics for about 1 month now. We've tracked the problem down to Vuforia being enabled in Unity. The crash is very simple:

    When the user kills the app by double clicking home button and swiping up to kill the app we're receiving a crash that we can't debug and find exactly where the problem is. By trial and error, we were able to track down the problem by using Vuforia+Unity together. The trick is: the issue ONLY happens on AppStore/AdHoc builds. Projects created without Vuforia enabled don't crash.

    You can easily reproduce this problem by:

    1. Create an empty Unity project;
    2. Add Vuforia to project;
    3. Add AR Camera to default scene;
    4. Build for iOS;
    5. Archive and create an Ad Hoc build;
    6. Install on device (drag IPA to iTunes)
    7. Run app;
    8. Close by double tapping home and closing app;
    9. Open Xcode device crash log

    An empty project with scene + AR Camera is able to reproduce the problem.

    Code (CSharp):
    1.  
    Vuforia Version: 7.0.36 - 7.1.34 (even when building with newest Unity 2018 the problem persists)
    iOS version: iOS9/10/11
    Models: iPhone4s/5/5c,7plus, iPad mini/2/3/4

    Can you please help us with this issue?

    Best regards.

    @Vuforia-Strasza

    This issue is not affecting directly our users because it happens when the user kill the app.
    But it's ruining all our analytics since these plugins submit their sessions and events during the
    applicationWillTerminate native callback. So this is an urgent matter to us.

    That's said, we continue to investigate this issue. By now we spent about 2 weeks of 3 developers to pinpoint what's the exact point that's causing the issue. Unfortunately, all we can guarantee is that's this issue is Vuforia related.

    It's very hard to debug since the Vuforia c# code is not open anymore and we can't attach the xcode debugger to a release adhoc build. We are trying to debug the bulk_vuforia il2cpp files but at this point, we are almost giving up.

    My guess is that's Vuforia could be trying to deallocate something that was previously deallocated or never initialized since it happens during the app termination flow.

    Hello @Vuforia-Strasza and @vuforia-dcordero,

    thanks for the quick reply. I've tracked the issue down to older version of Vuforia frameworks (6+). In older versions this crash wasn't so apparent because Vuforia wasn't automatically init. Using the same scenario we could produce this stack, which may be more informative:

    @pedrohba @CharlesBarros We have not encountered this issue when creating ad hoc builds of our samples using up to iOS 11.3. We're also not seeing anything Vuforia specific in the log you've shared above.

    We have not done builds yet with the iOS 11.4 beta, which is what I notice you are using in the above log. Are you building all of these apps using the XCode 9.4 beta? There might be an issue with this version we have not encountered.

    Can you confirm which version of XCode you are building with and share a log from a crash occurring in a version other than 11.4?

    The second crash log you've posted has a different error type (EXC_CRASH (SIGABRT) compared to
    EXC_BAD_ACCESS (SIGSEGV)). Which version of Vuforia + Unity are you using here?

    Hello Straza,

    we are able to reproduce this bug with XCode 9.2, we're not using Xcode 9.4. Also notice that step 8 involves killing the app while it is in foreground. Unity version doesn't appear to affect the problem since we were able to reproduce it with 2017.1.3p2 and newest 2018. We tested all Vuforia versions from 6.2.10 to newest and problem still occurs.

    Here is a crash with the production app (compiled using XCode 9.2):

    Code (CSharp):
    1.  

    Also please notice that I'm talking about the Unity Plugin Version. Vuforia iOS native version don't crash.

    Create an empty Unity project with Vuforia enabled, build it, create an ad hoc build, run on device and kill the app, that's the steps I take to reproduce the issue.

    Best regards,

    @pedrohba I've been able to reproduce this on an iPhone X with the latest Unity + Vuforia. I'm sharing this with the broader team and will provide you any updates in this thread.

    Hello @Vuforia-Strasza,

    thanks very much for your quickly reply. I'm happy that you're able to reproduce the problem! Let me give you a suggestion:

    why don't you guys from Vuforia open your Unity plugin? It would be easier for us to debug and help you fix this type of issue faster.

    Do you have any news about this issue?

    Best regards,

    While I agree this would let people such as yourself help us debug and resolve certain issues quicker, it also increases our overall risk by exposing more of how our SDK works to our competitors.

    The issue is still being investigated by the team, no update at the moment.

    @Vuforia-Strasza

    I'm not proposing that you should open your Vuforia SDK code, where your core business is. I've said that you should open your Unity+iOS plugin code because these are bugs lurking from very old versions and are creating a lot of
    problems, for example:
    • Vuforia has critical issues that occur simply by marking it on on Unity settings. Even if I don't use it on any scene the crash still happens. That is unacceptable for production code. Older versions didn't initialise Vuforia "automagically", that's why we weren't able to detect this issue before;
    • Bugs like the auto camera attach, auto rotation problems on some iOS versions, black screen on Xcode 9.3, etc;
    • Sorry, but Vuforia takes too long to fix these bugs. You could open your integration code, not the Vuforia tracking algorithms, so the community would even help you fix this issues faster without risking your core.
    You can easily see that the Unity+iOS is made of three parts:
    1. Managed dll linking to Vuforia SDK Wrapper; which can be decompiled (I've done it to see if I could find some problem with the initialisation and the code is not obfuscated :) )
    2. Wrapper around Vuforia SDK; -> this is probably where the problem probably is. I don't know why you guys are using this extra step but let's play along; While it's possible, although cumbersome and improductive, to evaluate how you guys are mapping calls to Vuforia native SDK, shouldn't create any issues regarding your core business (worst case scenario your competitors will know how to make Vuforia calls :) );
    3. Vuforia SDK -> I didn't even tried to decompile this one. I completely agree that this one must remain closed and I hope that you've obfuscated this part.
    Older version part 1 was open, now it's a managed Dll, but you should integrate 2 as open code, at least part of it, that's my suggestion. I've tried using your native iOS samples and they don't have this issues. Please, take this suggestion as a constructive criticism from a heavy Vuforia SDK user.

    Thanks very much for you quick replies and attention you're giving to our problem.

    Best regards,

    I am also getting this issue. Is this something that will be addressed in the next Vuforia update?

    @mitchtbh This is resolved in 7.2.

    There is also a work around for previous versions of Vuforia. Add the value "-u" to the "Additional Strip Flags" field in XCode before building. This should prevent the crash described in this thread.

    I'm getting crashes on exiting an AR scene, did this fix ever get released?
    Not sure if it's related but it's a hard crash immediately upon destroying the AR scene
    I'm using Vuforia 7.5.20 in Unity 2018.2.10

    Hello @monark,

    A fix was not generated as there was a workaround in 7.1 (the -u flag mentioned above). We tried to reproduce it in our 7.2 release but were unable to do so. Thus, we felt that no fix was required.

    Have you tried the proposed workaround?

    Thanks,
    Vuforia Engine Support

    Sadly this doesn't work for me.
    After a few times of entering and exiting the AR scene I get this crash

    -> 0x106f38f5c <+92>: ldp q2, q3, [x16] Thread 3: EXC_BAD_ACCESS (code=1, address=0x142c30080)

    Hello @monark,

    Can you send the full stack trace from the crash? This will help us a lot to better isolate.

    Thanks,

    Fingers crossed but the latest patch seems to have fixed it - 7.5.26
    I was able to go in and out of AR more than half a dozen times without a crash!

    I have only one outstanding issue at the moment now. I have to have force fulls screen on
