iOS Crash on App Start with this error: symbol '_$s10Foundation10CocoaErrorV4CodeVAA01_cD8ProtocolAAMc' not found, expected in '/System/Library/Frameworks/Foundation.framework/Foundation'

[shaymolho]

This crash occurs on iPhone SE 2016 with IOS 13.4.1
Using lastest air sdk 50.2.3.3 and latest x code 14.3.1
crash log is here
crash-2023-08-16-093209.ips.zip
on another iOS the app works fine
device logs here
log2.txt

ipa is here
https://easyupload.io/4hzsvc
any idea?

[shaymolho]

@ajwfrost @marchbold

[ajwfrost]

Yes, according to the latest iPhoneOS SDK, that symbol is found in the Foundation framework, but it seems on older phones this isn't the case and the app should instead pick it up from the Swift library. Potentially we can change the linker order to try to get this working, but we may need to check how it handles it when you use Xcode for this directly.

I assume you have an ANE involved here?

See also #2685

[shaymolho]

Hi @ajwfrost ,

Is there a solution for this problem?

What is the miminum iOS version for app not to have this crash?

We currently cannot issue new iOS builds because of this issue,
and waiting for you for further steps.

This is project.apm (note not using Iron source nor using any iron source mediations)
project-apm.zip
here is app descriptor
my-app-ios-decriptor.zip
We're building the ipa on macOS.

Thanks

[ajwfrost]

Hi

Can you please try re-packaging using the ADT version from the attached (this can be copied over the latest AIR SDK, in the "lib" folder, once it's unzipped..)

I am hoping that the re-ordering of the linker commands will mean that the symbols are picked up from the Swift foundation library now, rather than the framework...

It would be good if you're also able to have logging enabled when building, either via an adt.log file or via the AIR SDK Manager "troubleshooting" tab, so that we can see the updated ld64 command line...?

thanks

Andrew

adt.zip

[shaymolho]

Hi @ajwfrost
This still doesn't work
attached adt.log
adt.log

[ajwfrost]

Hi

The linking line has -lSwiftCompat but I would also expect to see -lswiftCoreFoundation in order to get the right symbols included... are you able to add that in to the ANE?

thanks

[shaymolho]

Hi
how to do that?
in the final linking line you expect only
-lswiftCoreFoundation or also
-lSwiftCompat as well?

[marchbold]

@shaymolho Are you using our ANEs? Let me know which ones and I'll add this flag into it for you.

[ajwfrost]

I would assume both libraries are needed here.

Is the swift code (that's in these ANEs) part of some third party components? If not, do we know whether there's usage of something like the CocoaError structure? https://swiftinit.org/reference/5.6.1/foundation/cocoaerror

I'm wondering whether this is behind that missing symbol... (hoping we could perhaps set up a reproduction of this scenario here!)

thanks

[shaymolho]

@marchbold yes, u can see the app descriptor in a few comments above
i attached it again here
my-app-ios-decriptor.zip

[shaymolho]

the ANE that adds the lSwiftCompat is
com.google.firebase.core.ane

[marchbold]

Yep, I'll get a test version of it built this morning.

[marchbold]

This build has the flag: com.google.firebase.core.ane.zip

[shaymolho]

did u change anything else or just added the flag to platform,xml? because i built with manually adding this flag (adt.log attached) and still crashes:
adt.log

[marchbold]

I just added the additional flag. I don't see it in your log though are you certain you updated? Make sure you clear all caches etc if using an IDE.

[shaymolho]

i see it in the log:

[marchbold]

Ah there are two builds in the log, I only looked at the first one which doesn't have it.

[shaymolho]

i"m trying with your ANE now, will update soon
any other idea if doesn't work?

[shaymolho]

device-log.txt
attached the device log (from my manual adding the flag attempt)

[shaymolho]

crash-log.zip
this is the crash, the other one is device

[shaymolho]

@ajwfrost
adding the flag -lswiftCoreFoundation didn't solve the problem with the suggested adt.jar.
attached adt.log
adt.log

[ajwfrost]

Hmm.. so despite that, it's still got the missing symbol:

expected in '/System/Library/Frameworks/Foundation.framework/Foundation'

Will need to check a bit further - we can just exclude it from the Foundation stub, but we'd likely have a number of symbols that need to change here..

thanks

[shaymolho]

ok, thanks
let me know if i can help

[sthompson-crestron]

Trying to help, I did a build the 50.2.3 SDK and with the adt.jar posted here. In both cases, when running the application on 15.7.8 I got the following error:

dyld[1163]: Symbol not found: (_$s10Foundation4DataV15withUnsafeBytesyxxSWKXEKlF)
Referenced from: '/private/var/containers/Bundle/Application/372BA38F-28BF-413E-A524-E80A98A26965/andros.app/CA_dbg_phone'
Expected in: '/System/Library/Frameworks/Foundation.framework/Foundation'

I will have to investigate how to generate a log file out of adt as my commands are wrapped up in build scripts that I'll have to poke around in.

[sthompson-crestron]

I added -lswiftFoundation to the XML file for my build and it now runs without issue on 15.7.8. I also have SwiftCompat on there too.

    <option>-lswiftFoundation</option>
    <option>-lSwiftCompat</option>

[marchbold]

(iOS 12-15 seems to be working with this one so same result there).

[ajwfrost]

Okay thanks - we'd better address that simulator swift linking issue..

(iOS 12-15 seems to be working with this one so same result there).

Just to check, does this mean the crash-on-startup reported under https://github.com/distriqt/ANE-Firebase/issues/462 looks like it's fixed with this update to ADT in conjunction with your latest ANE update?

thanks

[marchbold]

Yep, that one should be resolved with this update. Just the simulator issue now

[ajwfrost]

So currently there's the "libSwiftCompat.a" archive in the SDK 'lib' folder, and I'm assuming your ANE will be including the -lSwiftCompat additional command should it need this? But this didn't help in terms of the Simulator build, because that archive only had the arm64 files in it...

Below is a zip that contains an updated version of libSwiftCompat.a which is a fat/universal file with arm64 and x86_64 versions, if you unzip this into the SDK lib/aot/lib folder, and try again, I would hope this time it works..!

thanks
swiftCompat.zip

[marchbold]

Bingo! Looks good with that addition :)

(Yep our ANEs that rely on this have the -lSwiftCompat option, should see it in the command line I posted above)

[shaymolho]

Hey @ajwfrost,

Maybe it's a different issue i don't understand ,
but now running the simulator build failed on the following error:
Failure in codesign request
The same build not for simulator succeed

(By The way, where can i find the adt.log file? can't find it in the user home dir)

Thanks

[ajwfrost]

Curious one .. the adt.log file should be under /Users/username/adt.log but only if you've configured this to appear, by adding a line "DebugOut=true" to a file /Users/username/.airsdk/adt.cfg.
Or the simpler option: use the AIR SDK Manager (where you can tick a box to set up the logging, or you can just go to the "Troubleshooting" pane and ADT will magically log to this area...

thanks

[raresn]

@marchbold Our issue on #2860 is the same as @takazawa-gg described! (Can't run on ios < 16)
Problem is that we have it live on AppStore.
You can change AppStore to Romania, and download https://apps.apple.com/ro/app/ontimeagenda/id1327348934

[shaymolho]

Hi @ajwfrost ,

As I wrote now the simulator build fails on this error:
Failure in codesign request

I'm attching the adt.log from this build:
adt.log

The same build with 'ipa-debug' target works.

I don't know how to proceed from here,
Your help is much needed.

Thanks

[shaymolho]

Hi @ajwfrost,

Waiting for your response.

Thanks

[ajwfrost]

Hi @shaymolho - we're not able to reproduce that here and the log file doesn't really suggest much happening on the code-signing front! A couple of options perhaps:

• can you try editing the adt.cfg file and uncommenting/adding the line: UseNativeCodesign=true
• alternatively can you just remove the signing arguments from your command-line? Simulator builds don't need to be code-signed I believe...

thanks

[shaymolho]

HI @ajwfrost ,

I did both things and it didn't work.
I also tried to upgrade to the latest AIR 50 version. This didn't work either.

We need this app in simulator mode,
and it just doesn't work.

What can i do now?

[shaymolho]

@ajwfrost maybe u can add more logging to pinpoint the codesign issue?

[shaymolho]

@ajwfrost reminder
we cannot build simulator right now

[ajwfrost]

Hi - thanks for the reminder, we can put together an ADT version with some additional logging per your suggestion; to start with though are you able to enable debugging and confirm what it says in terms of the command-line for the code signing? The simplest way to do this is to have the AIR SDK Manager installed, and open this to the "Troubleshooting" page?

thanks

[mrfrasier]

Just found this thread. Users of our live app are reporting crashes when on older iOS versions. We don't have an older iOS device here to test with, but so I understand, do we need to do the following?

• Overlay adt.jar into current SDK (we're using 50.2.3.6
• add the lswiftFoundation and lSwiftCompat options to our xml
• overlay libSwiftCompat.a file @ajwfrost linked above

Then we're golden?

Separately, @marchbold I see you linked a test version of Firebase up there. Could this also solve the issues I've had (and reported elsewhere) building the app for iOS with Firebase included?

Thanks guys

[ajwfrost]

Hi @mrfrasier - the changes from above for ADT and libSwiftCompat.a should be in 50.2.3.6 already, so in terms of the crash on older iOS versions, that should have been fixed by that (iirc, a re-ordering of the libraries/frameworks that we link against..)

thanks

[mrfrasier]

Thanks for the reply. My app is actually built with 2.3.6 with the updated overlay files as that solved another issue I was having, but my users still report that the app crashes right back out on iOS versions under 16. I did manage to get my hands on a device and witnessed the same behavior sadly.

What data can I provide to help track down the issue?

[ajwfrost]

If you're able to get the crash report it would be handy .. Settings -> Privacy & Security -> Analytics & Improvements -> Analytics Data, then you'll see a long list of crash reports, if you find yours by process name (filename from the app descriptor file) there's a "send to" option at the top right of the screen.

thanks

Hi Andrew, please see attached
Crash-Log.zip

[ajwfrost]

Thanks .. that does look similar to the issue we were getting with the out-of-order linking, although not a symbol/library that I recognise:

Termination Description: DYLD, Symbol not found: _$sSS10FoundationE19_bridgeToObjectiveCSo8NSStringCyF | Referenced from: exe_file | Expected in: dyld shared cache

But again with "Foundation" which is the issue we had earlier, where symbols were expected to be in Foundation but weren't. This may be the other way round..! Did you build this on Windows, or macOS? And are you able to provide the ld64 command line (if you use the SDK Manager Troubleshooting tab, when packaging the IPA file it should display this line..)?

[mrfrasier]

Yup, on Windows here. here is the ld64 command (this build fails because I'm simultaneously trying to figure out a Firebase issue with Michael and that problematic ANE is present, but figured you just needed to see the general command) This is on 50.2.3.7

I have similar feedbacks from users (IOS < 16)

Windows
AIR50.2.3.6 (with ld64 update from @marchbold post)

P.S. I check the same version of ld64 is within AIR50.2.3.7 now

[ajwfrost]

Hi

So that missing symbol appears a few times online, seems to have caused a number of issues.. but to try to work out where it would come from: we have it in three places in the latest iPhone SDK:

• /usr/lib/libextension.tbd
• /usr/lib/swift/libswiftFoundation.tbd
• /System/Library/Frameworks/Foundation.framework/Foundation.tbd

In the binary above, it seems to be looking for it in the dyld cache..
The linker arguments suggest it should look first in libswiftFoundation before the Foundation framework, and there's no mention of the "extension" library in the build command. But each of the references have also got ios-version specific annotations...

This may be something related to how we're handling these TBD files and turning them into libraries, potentially we're seeing them coming from the wrong place. You're both using Windows to compile this, do you have any access to a mac to try that? I would be interested in the results both with and without the -platformsdk option.

In terms of reproducing this: do you know if it's 100% reproducible, with the binaries you've built on Windows, when using the older (iOS 15 and earlier) versions? Also, I don't think we've ever got a reproduction scenario so is there any chance we could get a set of files (XML/SWF/ANEs) so that we can package it and test it here to reproduce the problem?

We have a potential workaround, although a lot of that may depend on whether it also fails if you built it on a macOS machine using the -platformsdk argument, and it may then mean we have to be creative when it comes to distributing some of the SDK components that are subject to third party agreements..

If you can help with a reproduction - either by sending us your app files, or by trying something out for us if you're able to reproduce things there - then please email me, andrew dot frost at harman dot com..

thanks

[Mintonist]

Can production version of app help you? You will see crashes on old IOS versions.
Or I can send you all used ANEs.

[ajwfrost]

As long as it's in a form that we can package up an IPA from it .. but just getting an IPA is probably of limited value as we'd not be able to do much to tweak the settings and try to reproduce and then fix it..
A list of ANEs could be helpful though. We'd used the "com.distriqt.Bolt" one as I thought that had got some Swift dependencies in it which may have triggered this issue..

[marchbold]

@Mintonist Please do not distribute our ANEs on public forums.

[Mintonist]

@marchbold please excuse me! my mistake...
I've also removed link and files
