I develop an IOS SDK, which developers can implement it to their apps as a framework.
I’m currently using Sentry as crash analysis tool, and the related DSYM file (produced from my SDK project) is automatically uploaded to Sentry on every build.
But the problem is when someone’s app crashes due to an error on the SDK I’m developing, Sentry returns partially symbolicated crash logs that I can barely understand what has happened and where the crash has occurred.
Is there a way that I can get the fully symbolicated crash logs, without changing the app’s project settings and without uploading anything (app’s DSYM etc.) from the original app. (Since I don’t have the app, I’m only producing the SDK)
My project has the following build settings:
Strip Debug Symbols During Copy: No
Strip Style: Debugging Symbols
Strip Linked Product: No
I was sending the DSYM's to a wrong project. I set 'export SENTRY_PROJECT=proper_project_name' then the issue has resolved.
Here is the link of the issue;

I just implemented Fabric Crashlytics tool to my Xcode project via Swift Package Dependencies.
All works good if I enable Google Analytic on a step when I create an app, without this step I did not received crash reports, so I switched to the app with Google Analytic enabled.
I've tested crash button from the link:
One comment that I don't like from there
"After your app crashes, run it again from Xcode so that your app can
send the crash report to Firebase."
Does it mean that user has to reopen app to send crash report? For example if a user download an app from the App Store and then somehow the app is crashed. Does mean that reopening app required for sending that crash? And if the user will not open the app it means I lost this crash report? I understand that on live store there is no option to re run it form Xcode, but reopening seems a require step.
I suppose the crash report should work different a bit by sending issue details right after a crash, I may be wrong here.
Also when I set everything via Swift Package Dependencies looks like I don't have an option to upload dSYM via this option
/path/to/pods/directory/FirebaseCrashlytics/upload-symbols -gsp /path/to/GoogleService-Info.plist -p ios /path/to/dSYMs
Does this mean I need to pull Fabric and Crashlytics from CocoaPods?
I've switched off bitcode at the moment and looks like all is works automatically but not sure it is good idea for long perspective.
Yes, crashes will be uploaded when restarting the app after it crashes. As far as I know, this is because the SDK may not have enough time to actually send the report when the crash happens.
If you are using Swift Package Manager, you still have that option.
This is the command:
"${BUILD_DIR%/Build/*}/SourcePackages/checkouts/firebase-ios-sdk/Crashlytics/run"
If the app has bitcode enabled, then you'll need to download the dSYMs from the App Store and upload them manually.
Lastly, Fabric is now deprecated so don't download it. You don't need to use Cocoapods if you are already integrated Crashlytics with SPM.
Question #1:
I am using Crashlytics for one of my commercial iOS Apps. Their service seems very helpful. I wonder if there is any Legal issue of using their services for commercial apps? Is there any limitations for using Crashlytics?
Question #2:
I need to upload .dsym file in their server to get crashlogs symbolicated. Is there any privacy issue. Is it possible to get my code (or any info) back by reverse engineering when they have .dsym file.
Question #3
Sometime some crashes are not showing in the crashlytics dashboard. Is it necessary to be online when crash happens to get crashlog in dashboard? Don't Crashlytics keep logs trace when offline and send logs back to the server when device become online? Any idea how they work?
Mike from Fabric here, but I'm not a lawyer.
1) Fabric and Crashlytics is used in many commercial apps, including our own. There aren't limitations to using Fabric. You can find the Fabric terms of service here.
2) The dSYM is what let's us or any other crash reporter symbolicate the crash report as it contains the symbols that map back to your app's source. None of your source code is uploaded. From Apple's own documentation:
As the compiler translates your source code into machine code, it also
generates debug symbols which map each machine instruction in the
compiled binary back to the line of source code from which it
originated. Depending on the Debug Information Format
(DEBUG_INFORMATION_FORMAT) build setting, these debug symbols are
stored inside the binary or in a companion Debug Symbol (dSYM) file.
The Debug Symbol file and application binary are tied together on a
per-build-basis by the build UUID. A new UUID is generated for each
build of your application and uniquely identifies that build. Even if
a functionally-identical executable is rebuilt from the same source
code, with the same compiler settings, it will have a different build
UUID.
3) Crashes are caught regardless if the app is connected to a network or not. However, crashes are only sent on relaunch of the app and would then be processed.
One thing to note is that if you're testing in the Simulator or with your device connected to Xcode will cause Xcode's debugger to capture the crash instead of us.
Further, if the dSYM hasn't been uploaded, then we're unable to process the crash report and we'll alert you in the Crashlytics dashboard of the missing dSYMs so that you can upload them.
I have Implemented Fabric Crashlytics in my project manually. And in my application I'm using an external device connection for that I'm using an SDK, so for that SDK I have set bitcode to NO in my project. Before It used to work fine and I used to find my crash reports in crashlytics. But all of a sudden since from a week It is asking for missing DSYM files, and I'm not able to find any crash reports in crashlytics Dashboard. I have followed Fabric Doc and tried to upload DSYM zip files manually. But no luck as I got stuck in the same page with processing message as shown in below link.

Can any one walk me out from this? Thanks In Advance.
I am building an iOS app using react-native. I am distributing the app using TestFlight. Every once in a while, I would see a crash reported on TestFlight. When I look at the crash info in Xcode, it doesn't tell anything about what part of JS code may have caused the crash. Below is a sample crash log I get on Xcode. Here App refers to my app name.
Since these crashes occur only intermittently, and the above stack trace points to very generic methods, I am not sure how to go about debugging such crashes.
Please share what would be a good strategy to debug these crashes.
I've been getting a bunch of crash logs for my (largely c++) app on iOS. My problem is I can't seem to ever symbolicate these crash reports properly.
What is the "proper" setting for stripping debug symbols for release on iOS? I get that you'd want to strip the debug symbols so the download size of the app isn't ridiculously large.
But the problem is that it seems to make the crash reports virtually unreadable.
Do dSYM files on the xcode archives get sent and eventually downloaded by the users?
Or is it simply something to be kept for future symbolicating purposes (done locally on my own machine, on xcode)?

This. Your "release" config (or whichever config you use for distribution) should have the following setting:
Symbols Hidden by Default: Yes
Xcode will still generate a dSYM folder which is what you will use for symbolicating crash logs. There are 3 ways to handle symbolicating:
Use Xcode. For this you need to use the Product -> Archive feature whenever you release. Once an archive is created, you can select "Export" then "Save for iOS App Store Deployment". After this you can drag crash logs into the left side of the "Device Logs" window and Xcode will symbolicate them for you.
Manually symbolicate using the symbolicatecrash tool located inside your Xcode.app folder. This is useful if you've released code to users but don't have an Xcode archive. You need to be sure that the crash log matches the binary and dSYM or it will not work.
Use a third party tool that collects crash reports and symbolicates them for you. Examples include Crashlytics, Bugsense, or HockeyApp.
