Wrong K/N stack trace in debug iOS framework #3234

We have a trouble with stack trace on iOS side. As it mentioned here #2600 in release mode we cannot have a good stack trace for now, but we compiled KN lib in debug mode and stack trace is still wrong. We have an iOS project and a K/N project. When we got a crash it's logged to Crashlytics. Stack trace looks like:

KotlinNativeExample - iOS project
KNModule - K/N lib

0 libsystem_kernel.dylib
__pthread_kill + 8

1 libsystem_pthread.dylib
pthread_kill$VARIANT$mp + 380

2 libsystem_c.dylib
abort + 140
arrow_right 

3 KNModule
ResumeMemory + 10

4 KNModule
TerminateWithUnhandledException + 96

5 KNModule
konan::consolePrintf(char const*, ...) + 106

6 KNModule
kfun:kotlin.Float.<unbox>(kotlin.Any)kotlin.Float + 740

7 KotlinNativeExample
ViewController.swift - Line 27
ViewController.anotherFunc() + 27

8 KotlinNativeExample
ViewController.swift - Line 22
ViewController.buttonClicked(_:) + 22

9 KotlinNativeExample
<compiler-generated> - Line 0
@objc ViewController.buttonClicked(_:)

The crash happened inside a testCrash() func by throw NotImplementedError()

The K/N project was compiled (in debug mode) by using https://github.com/AlecStrong/kotlin-native-cocoapods plugin. After compilation we have dSYM files. The first one for iOS project and the second one for the K/N lib. (dSyms also was generated by AlecStrong/kotlin-native-cocoapods plugin). Both dSym files was uploaded to Crashlytics but the stacktrace is still wrong. Is there any idea how to get a good stacktrace in Crashlytics? This is happening only with Crashlytics, If I got a crash in Xcode it has a good stack trace.

Have you enabled rebuild from bitcode when uploading to AppStore?

I haven't upload this project to AppStore yet. Bitcode for the iOS project is disabled. I took a dSym file for the iOS project from DerivedData/etc../ and uploaded it to Crashlytics. Is it should be enough to show a good stack trace? Or I have to upload it to appstoreconnect first (actually I don't see any reason why)?

Yes.

I took a dSym file for the iOS project from DerivedData/etc../ and uploaded it to Crashlytics.

Please ensure that you can manually symbolicate crash log, e.g.

DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash -v yourCrashReport.crash

You should get properly symbolicated stack trace, and verbose output should contain MATCH line with the dSYM you are using. Is this true?

MATCH line contains path to dSym I am using for KN.

Please ensure that you can manually symbolicate crash log, e.g.

There is stack trace I got:

It looks better (I can figure out what kind of exception happened), but some function's names is still unavailable.

It looks better (I can figure out what kind of exception happened)

So Crashlytics appears to ignore "Last Exception Backtrace" of the crash, reporting terminating thread backtrace instead.

but some function's names is still unavailable.

Could you provide an example?

Could you provide an example?

In backtrace 3d and 4th lines:

3   KNModule                             0x1009224ec kfun:Test.throwException() + 58604 (Test.kt:12)
4   KNModule                             0x100922350 0x100914000 + 58192
5   KotlinNativeExample               0x10063a9e0 0x100634000 + 27104
6   UIKitCore                         0x1d1371e4c -[UIViewController loadViewIfRequired] + 999

So Crashlytics appears to ignore "Last Exception Backtrace" of the crash, reporting terminating thread backtrace instead.

Ok, got it. Is there any ways to handle it?

What's wrong with 3rd line?

4 KNModule 0x100922350 0x100914000 + 58192

This is likely a bridge, it is not supposed to be decrypted.
Is throwException the function you call from Swift?

Consider reporting unhandled Kotlin exception to Crashlytics explicitly. Unhandled exception can be detected using https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.native/set-unhandled-exception-hook.html

Typo, I meant 4th and 5th lines, but I guess 5th line is just a bridge too.

Yes

I'll try it, thank you so much.

5 KotlinNativeExample 0x10063a9e0 0x100634000 + 27104

This is Swift (or Objective-C) code, K/N has nothing to do with this line.
May be caused by missing dSYM for the main binary (KotlinNativeExample).

Btw, is it short(or middle) term fix? Do you have a plan to handle it? Is it even possible to fix?

We are improving support for analyzing production crashes currently, some of this work will be included into 1.3.60.
Improving experience with third-party crash analytic tools (like Crashlytics) is considered too, but we don't have any details or ETA yet.
