I have an app in beta using TestFlight and I have been noticing crash reports appearing.
most of the reports are this
If I click on the button Open in project in the Organizer it takes me no where
This appears to be an internal crash correct?
How can I find out what UIBarButtonItem is causing the crash?
I Hope this will help you: Apple doc Crash Report , as you can see in the doc in the Listing 4 the crash report is fully symbolicated , Listing 6 shows partially symbolicated crash reports which looks like your case
From Apple Doc
You must keep both the application binary and the .dSYM file in order to be able to fully symbolicate crash reports. You should archive these files for every build that you submit to iTunes Connect. The .dSYM and application binary are specifically tied together on a per-build-basis, and subsequent builds, even from the same source files, will not interoperate with files from other builds. If you use Xcode's Build and Archive command then they will be placed in a suitable location automatically. Otherwise any location searchable by Spotlight (such as your home directory) is fine.
For more information about this you can check portion after Listing 6 in Symbolication
you can use crashlytics for identifying where the app is crashed.It will give the Controller name and line number of code also.

I have implemented a Firebase crashlytics in my project, and also I have configured the firebase account with my project. But when I do a crash with the help of Crashlytics.sharedInstance().crash() I will get crash crash report perfectly. But if I do a crash with any other method, it is not showing up the crash report. But some crashes are showing in the dSYMs tab in crashlytics and it is not formatted correctly. I have downloaded the dSYM file from the iTunes store and uploaded to Crashlytics through terminal. But Still I am getting the crashes in the dSYMs tab and not formatted correctly.
This is How I am getting crash report in dSYMs tab in Crashlytics.
Does anybody know what I am doing wrong here?
I could able to implement it in my Swift project and it correctly decrypted the errors and displayed correctly. But when I implemented it into my Objective-C project, I am not getting the correct decrypted report.
When having "optional" missing dSYMs, those are usually related to .frameworks or other third party library being used. If you only have these kinds of missing dSYMs, the dashboardwill show the crash report, but the frames related to those dSYMs won't be symbolized.
DSYMs marked as "required" are related to your main app, when those are missing, the dashboard won't show the crash report.
Usually, when using a .framework, the dSYMs files should also be available, but if not, you'd probably need to get them from the framework owners.
To elaborate Gerardo's answer further, please refer to your Xcode Organizer. There goes a list of your app published with different version. Download the dSYM
reports first and hence follows the procedures given from Google and submit those dSYM to firebase
Make sure you have already installed the latest version of FirebaseCrashlytics via Cocoapods and proper app profile at your Firebase Console.

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 been observing this that when ever my app crashes i get the crash log and try to symbolicate it but following happen
When I use xcode to symbolicate, it never symbolicates the addresses of the crash
When I use atos command specified developer.apple.com technotes it either gives some other class function name that does not have to do any thing with the crash
I have used other methods like symbolicatecrash script but the result is same as before.
I also tried solution given stackoverflow.com/questions/7932992 but did not succeed
I created a demo crash and tried to change my scheme of the app for "Run" and changed "build configuration" to "release" to check if the crashes symbolicate when I run the app directly to device, I test the app, the demo crash occurs and in this case the crahes get symbolicated.
I created a demo crash in a new app and created an archive and export IPA, used this ipa in a device to recreate that crash but still xcode could not symbolicate that crash.
I don't get why is it behaving this way,
I looked into the archives to find my dSYM file and can locate it there but could not symbolicate it using any of the processes stated above.
A guidance will be helpful!
I was working with code back to see if there can be any impact of bitcode with help of a friend, found that while exporting archive to IPA, it asks me to rebuild with bitcode (which was checked) I just tried and unchecked it to create the IPA and this time my app crash logs were symbolicated, I still don't know why this happens because apple recomends to rebuild with bitcode while submitting apps.
I am looking for more answeres for why is it happening?
Will keep you posted (also a enlighten me if there are any misses.)
Is there any way to get crash information in iTunes Connect? I notice under App Analytics it displays the number of "Opt-in Only Crashes". I press the number under it (in my case 2). This takes me to a page that only seems to show the days that the crash happened. Is there any way I can see useful crash information, for example line of code, etc.?
To see where is the problem just open your Xcode > Window > Organizer > Crashes from your Application.
You already deployed your app on App Store (or as an Ad Hoc or Enterprise build) then you won't be able to attach Xcode's debugger to deployed app for debugging. To debug problems, you need to analyze Crash Logs and Console output from the device. To read crash reports with backtraces its need to be symbolicated before they can be analyzed. Symbolication is a process which replaces memory addresses with human-readable function names and line numbers.
To understanding and Analyzing Application Crash Reports you can refer Symbolicating Crash Reports, Debugging Deployed iOS Apps or Analyzing Crash Reports.
Overview of the crash reporting and symbolication process.
Set Debug Information Format (DEBUG_INFORMATION_FORMAT) in build settings these debug symbols are stored inside the binary or in a companion Debug Symbol (dSYM) file.
When you archive the application for distribution, Xcode will gather the application binary along with the .dSYM file and store them at a location inside your home folder.
At the time of deploying on the App Store or a beta test using Test Flight, include the dSYM file when uploading your archive to iTunes Connect.
When your application crashes, an unsymbolicated crash report is created and stored on the device.
You can retrieve crash reports directly from their device by following the steps in Debugging Deployed iOS Apps. If you have distributed your application via AdHoc or Enterprise distribution, this is the only way to acquire crash reports from your users.
Crash reports retrieved from a device are unsymbolicated and will need to be symbolicated using Xcode. Xcode uses the dSYM file associated with your application binary to replace each address in the backtrace with its originating location in your source code. The result is a symbolicated crash report.
If the user has opted to share diagnostic data with Apple, or if the user has installed a beta version of your application through TestFlight, the crash report is uploaded to the App Store.
The App Store symbolicates the crash report and groups it with similar crash reports. This aggregate of similar crash reports is called a Crash Point.
The symbolicated crash reports are made available to you in Xcode's Crashes organizer.
Yes, You can view those crashes in Xcode. This can found in apple docs in Analyzing crash reports
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)?
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.
