crash log does not symbolicate system libraries armv7s - ios

I am trying to analyse a crash log that a customer sent me, but I cannot get it to symbolicate the system library calls. It does symbolicate calls to my own methods correctly. That does not make it very practical to analyse what goes wrong.
I have run 'symbolicatecrash -v', to see what is causing the lack of symbolication. The likely cause is this:
## /Users/baraupp/Library/Developer/Xcode/iOS DeviceSupport/6.1.3 (10B329)/Symbols/usr/lib/system/libsystem_kernel.dylib doesn't contain armv7s slice
I have checked the mentioned libraries with 'lipo', which says that they contain 'armv7' but no 'armv7s'. After searching the web, it came out that this is a difference between iPhone 4 and iPhone 5. The normal solution seems to be to plug-in an iPhone 5 device and download the libraries from there. But I don't have an iPhone 5.
Anybody knows how to solve this?
To give you an idea how the symbolication looks like:

There are only two ways to solve this:
You either need an iPhone 5 device with iOS 6.1.3 to plug into your computer so Xcode can import the symbols
Or you need to get the symbols from another developer and replace yours with them.
Usually the symbols are part of the latest Xcode release, but Apple doesn't always provide Xcode updates when an iOS version only contains bug-fixes but no API changes.

I ran into this issue as well with an iOS7 app using XCode5, even though I had all the correct symbols.
What I found was that I had taken my dSYM file out of the archive where spotlight could index it, but the crashlog was only getting partically symbolicated (as seen in the question). But I had left the actual .app file in an xcarchive, and it was not able to be indexed by spotlight. As soon as I copied that file out of the archive to the visible location, I was able to symbolicate properly.

You can install related Xcode with your target version of iOS and copy ~/Library/Developer/Xcode/iOS DeviceSupport/

Missing dSYM for UIKitCore, CoreFoundation, etc

I am trying to symbolicate an iOS crash report. I am missing dSYMs for UIKitCore and other native libs.
The app is built with NativeScript. I have successfully symbolicated frames of my app and NativeScript framework. However I can't seem to find a way to symbolicate frames of libs like UIKitCore, they are still showing up as addresses. I have also tried searching for them using mdfind as per Apple documentation - they are not present on my Mac. I have also tried looking for these dSYMs online without luck.
Here is an excerpt of my crash log:

Many articles I found had examples with UIKitCore symbolicated so I assume this has to do with my configuration.
Part 1: Install the symbols
Check the full iOS version in the crash report. It should look like "iPhone OS 13.3 (17C54)"
There are a lot of repositories with iOS symbols or links to them. Like this one: https://github.com/Zuikyo/iOS-System-Symbols/blob/master/collected-symbol-files.md
Find and download symbols you need.
Unpack them to ~/Library/Developer/Xcode/iOS\ DeviceSupport
Add info.plist into the root folder if it missed (just copy from the other symbols and change its version value)
Part 2. Use the force of Xcode
Connect ANY real device, open Xcode, open the "Devices and Simulators" window, click the "View device logs" and then go to tab "All logs".
Drag and drop the crash into the table. Find it.
If the system symbols are not desymbolicated – do right-click on the crash and select "Re-symbolicate crash".
Repeat Step 3 multiple times (2-3 usually enough) – it needs time to resymbolicate it, but it looks like xcode does not update the crashlog automatically
And yes, UIKitCore is a system framework
UIKitCore is NOT an apple framework.

APP Reject on Itunes

I have uploaded app on iTunes and iTunes rejected app continuously and provided crashlog. I have found issue like "-[AFNetworkReachabilityManager .cxx_destruct]".
Actually i have add AFNetworking using pods and i have also check latest version and it is there.
If any one have any idea about this problem then let me know.
Thanks in Advance.

App Store Review
It may case that your application network is not support IPV6 network. So apple will reject your application.
Check below points into your application:
1) Make sure you API link which you used in your application, doesn't have any ip address. If you calling API using IPAddress then your application will rejected.
2) Do testing your application using IPV6 network thorugh your system. Here is the link.

Persistent crash on my iOS App, unable to locate it

I'm searching for 5 days ago about this crash, but I can find why my app crash sometimes.
I'm using the Crittercism library to log my crash. The dSYM file is correctly uploaded on the Crittercism website. Here the crash log from Crittercism:
0 libobjc.A.dylib 0x38540626 objc_msgSend + 6

15 libdyld.dylib 0x38a43ab7 start + 3
The thing is: I have many UITableView in my app. But I can't find which one it is.
How do I have to process to debug this crash ? I didn't find some useful information on Apple Developer Center. I try to use the atos command to symbolicate the file, but no useful information. It's exactly the same info than on the Crittercism website.
Here the command I used: atos -arch armv7 -o myApp (to enter interactif mode, then, enter each memory address like : 0x307baaf7)
I have only the myApp.app.dSYM archive, and to use this command (above), I used the file the archive at path: Contents/Resources/DWARF/myApp
I'm really lost. Any idea ? Suggestions ? Thank you so much for your help.
EDIT 1:
I've checked all my UIAletView and delegate of UIAlertView: all is ok.
I see the crash log on Crittercism, (around 120 crashes for 63 users on iOS 7 only, iPhone and iPad).
I can't reproduced it ! I really don't understand.
Frame 14 already shows the correct symbol, which is main.m line 16. Using atos with the address as written in the stackframe like you did is wrong, see this stackoverflow explanation. As such it is not possible for a crash report to tell you which table view is causing such a memory issue.
Based upon the above you may not be able to get the exact table view from the stack trace itself, but with Crittercism there are additional features (such as Breadcrumbs) that allow for capturing a trail beyond just the stack.
My recommendation is to add a breadcrumb in the viewDidLoad of the TableViewController and grab/define the name of the table view there. That way you can step through the breadcrumbs and know that leading up to the crash you were in this tableview.
That should help you for better capturing this scenario in the future.
As for this particular stack trace. You can potentially use the techniques described in this post to help you better understand the true origins of the objc_msgSend.

Crash log partially symbolicated [duplicate]

I am trying to analyse a crash log that a customer sent me, but I cannot get it to symbolicate the system library calls. It does symbolicate calls to my own methods correctly. That does not make it very practical to analyse what goes wrong.
I have run 'symbolicatecrash -v', to see what is causing the lack of symbolication. The likely cause is this:
## /Users/baraupp/Library/Developer/Xcode/iOS DeviceSupport/6.1.3 (10B329)/Symbols/usr/lib/system/libsystem_kernel.dylib doesn't contain armv7s slice
I have checked the mentioned libraries with 'lipo', which says that they contain 'armv7' but no 'armv7s'. After searching the web, it came out that this is a difference between iPhone 4 and iPhone 5. The normal solution seems to be to plug-in an iPhone 5 device and download the libraries from there. But I don't have an iPhone 5.
Anybody knows how to solve this?

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
In order to use MonoDevelop's profiler you had to enable the SGEN garbage collector (GC). This is (from the stack trace) what's causing your crash.
You need to go back to your project's options (MonoTouch Build) and, under the Advanced tab, unselect the "Use SGEN generational garbage collector".
Once you have changed this, re-build your solution and it should work fine (the reason it works for release build is because the GC settings, like most of them, are kept separate between Debug and Release builds).
Now there's likely something broken because it should not be crashing like this. Would it be possible for you to report this issue (with a test case) to http://bugzilla.xamarin.com so our GC developers can get a look at what caused this issue ? Thanks!
