How to symbolicate crash log Xcode

Question

Xcode 5 organizer had a view which would list all the crash logs  and we could drag drop crash logs here  But since Xcode 6  I know they have moved devices out of organize and have a new window for the same  But I do not find a place where I view the crash logs which i drag-dropped in Xcode 5 after upping to Xcode 6  Anybody knows the answer

Follow these steps in Xcode 10 to symbolicate a crash log from an app build on the same machine    Inside Organizer  locate the archive where the app is based on  Click on the Download Debug Symbols button  Nothing will appear in your Downloads folder  but that s OK  Connect the build machine to an iOS device  Select the device in Devices and Simulators  Click on the View Devices Logs button  Drag-and-drop the crash file to the left panel  The file must end with a  crash extension  otherwise the drag fails  Switch to the All Logs tab  Select the added crash file  The file should automatically symbolicate  otherwise use the right-click context menu item Re-Symbolicate Log

The easiest process to symbolicate crash logs    preserve the xcarchive file from the organizer during IPA building process for future use  When the crash occurs  collect the crash logs from affected device  The extension should be  crash  If the crash log is in  ips format  just rename it to  crash  Double click the xcarchive from the stored path to make it appear in organizer if not present already   open in xcode window- devices and simulators -  view device logs -  all logs -  drag and drop the  crash file    Wait for 5secs  Bang  the application calls in stack trace will be symbolicated   You may still see a lot of symbols though  those are internal library and framework calls   This is the easiest one  tried and tested

From Apple s docs   Symbolicating Crash Reports With Xcode Xcode will automatically attempt to symbolicate all crash reports that it encounters  All you need to do for symbolication is to add the crash report to the Xcode Organizer    Connect an iOS device to your Mac Choose  Devices  from the  Window  menu Under the  DEVICES  section in the left column  choose a device Click the  View Device Logs  button under the  Device Information  section on the right hand panel Drag your crash report onto the left column of the presented panel Xcode will automatically symbolicate the crash report and display the results To symbolicate a crash report  Xcode needs to be able to locate the following    The crashing application s binary and dSYM file  The binaries and dSYM files for all custom frameworks that the application links against  For frameworks that were built from source with the application  their dSYM files are copied into the archive alongside the application s dSYM file  For frameworks that were built by a third-party  you will need to ask the author for the dSYM file  Symbols for the OS that the that application was running on when it crashed  These symbols contain debug information for the frameworks included in a specific OS release  e g  iOS 9 3 3   OS symbols are architecture specific - a release of iOS for 64-bit devices won t include armv7 symbols  Xcode will automatically copy OS symbols from each device that you connect to your Mac     If any of these are missing Xcode may not be able to symbolicate the crash report  or may only partially symbolicate the crash report

Make sure that your Xcode application name doesn t contain any spaces  This was the reason it didn t work for me  So  Applications Xcode app works  while  Applications Xcode 6 1 1 app doesn t work

Writing this answer as much for the community as for myself   If there ever are problems symbolicating a crash report  one can overcome them as follows    Create a separate folder  copy Foo app and Foo app dSYM from the corresponding  xcarchive into the folder  Also copy the  crash report into the folder  Open the crash report in TextEdit or elsewhere  go to the Binary Images  section  and copy the first address there  e g  0xd7000   cd into the folder  Now you can run the following command   xcrun atos -o Foo app Foo -arch arm64 -l 0xd7000 0x0033f9bb   This will symbolicate the symbol at address 0x0033f9bb  Please make sure to pick the correct value for the -arch option  can be obtaned from the first line in the Binary Images  section  or figured out from the Hardware Model  in the crash report and the app s supported archs    You can also copy the necessary addresses  e g  a thread call stack  from the crash report directly into a text file  in TextEdit  hold Option and select the necessary text block  or copy and cut   to get something like this   0x000f12fb 0x002726b7 0x0026d415 0x001f933b 0x001f86d3   Now you can save this into a text file  e g  addr txt  and run the following command   xcrun atos -o Foo app Foo -arch arm64 -l 0xd7000 -f addr txt   This will give a nice symbolication for all the addresses at once   P S   Before doing the above  it s worth checking that everything is set up correctly  as atos will happily report something for basically any supplied address    To do the checking  open the crash report  and go to the end of the call stack for Thread 0  The first line from the end to list your app  usually the second one   e g    34  Foo                    0x0033f9bb 0xd7000   2525627   should be the main   call  Symbolicating the address  0x0033f9bb in this case  as described above should confirm that this is indeed main   and not some random method or function   If the address is not that of main    check your load address  -l option  and arch  -arch option    P P S   If the above doesn t work due to bitcode  download the dSYM for your build from iTunes Connect  extract the executable binary from the dSYM  Finder    Show Package Contents   copy it into the directory  and use it  i e  Foo  as the argument to atos  instead of the Foo app Foo

There is an easier way using Xcode  without using command line tools and looking up addresses one at a time    Take any  xcarchive file  If you have one from before you can use that  If you don t have one  create one by running the Product   Archive from Xcode  Right click on the  xcarchive file and select  Show Package Contents  Copy the dsym file  of the version of the app that crashed  to the dSYMs folder Copy the  app file  of the version of the app that crashed  to the Products   Applications folder Edit the Info plist and edit the CFBundleShortVersionString and CFBundleVersion under the ApplicationProperties dictionary  This will help you identify the archive later Double click the  xcarchive to import it to Xcode  It should open Organizer   Go back to the crash log  in Devices window in Xcode  Drag your  crash file there  if not already present  The entire crash log should now be symbolicated  If not  then right click and select  Re-symbolicate crash log

Xcode 11 2 1  December 2019     Apple gives you crash log in  txt format   which is unsymbolicated          With the device connected             Download   txt  file   change extension to   crash             Open devices and simulators from window tab in Xcode   select device and select device logs   drag and drop  crash file to the device log window           We will be able to see symbolicated crash logs over there   Please see the link for more details on Symbolicating Crash logs

Ok I realised that you can do this    In Xcode  gt  Window  gt  Devices  select a connected iPhone iPad etc top left  View Device Logs All Logs   You probably have a lot of logs there  and to make it easier to find your imported log later  you could just go ahead and delete all logs at this point    unless they mean money to you  Or unless you know the exact point of time the crash happened - it should be written in the file anyway    I m lazy so I just delete all old logs  this actually took a while     Just drag and drop your file into that list  It worked for me

You can refer this one too  I have written step by step procedure of Manual Crash Re-Symbolication   Crash Re-Symbolication  STEP 1  Move all the above files  MyApp app  MyApp-dSYM dSYM and MyApp-Crash-log crash  into a Folder with a convenient name wherever you can go using Terminal easily   For me  Desktop is the most easily reachable place    So  I have moved these three files into a folder MyApp at Desktop   STEP 2  Now its turn of Finder  Go to the path from following whichever is applicable for your XCODE version   Use this command to find the symbolicatecrash script file  find  Applications Xcode app -name symbolicatecrash  Xcode 8  Xcode 9  Xcode 11  Applications Xcode app Contents SharedFrameworks DVTFoundation framework Versions A Resources symbolicatecrash  Xcode 7 3  Applications Xcode app Contents SharedFrameworks DVTFoundation framework Versions A Resources symbolicatecrash  XCode 7    Applications Xcode app Contents SharedFrameworks DTDeviceKitBase framework Versions A Resources symbolicatecrash  Xcode 6     Applications Xcode app Contents SharedFrameworks DTDeviceKitBase framework Versions A Resources  Lower then Xcode 6 Contents Developer Platforms iPhoneOS platform Developer Library PrivateFrameworks DTDeviceKitBase framework Versions A Resources  Or     Contents Developer Platforms iPhoneOS platform Developer Library PrivateFrameworks DTDeviceKit framework Versions A Resources  STEP 3     Add the found symbolicatecrash script file s directory to  PATH env variable like this  sudo vim  etc paths d Xcode-symbolicatecrash and paste the script file s directory and save the file  When opening a new terminal  you can call symbolicatecrash at any folder as commands located in  usr bin   Or  Copy symbolicatecrash file from this location  and paste it to the Desktop MyApp  Wait    Don   t blindly follow me  I am pasting sybolicatecrash file in folder MyApp  one that you created in step one at your favorite location  having three files    STEP 4  Open Terminal  and CD to the MyApp Folder   cd Desktop MyApp     Press Enter export DEVELOPER DIR   xcode-select --print-path         Press Enter    symbolicatecrash -v MyApp-Crash-log crash MyApp dSYM        Press Enter  That   s it    Symbolicated logs are on your terminal    now what are you waiting for  Now simply  Find out the Error and resolve it     Happy Coding

If you have the  dSYM and the  crash file in the same sub-folder  these are the steps you can take    Looking at the backtrace in the  crash file  note the name of the binary image in the second column  and the address in the third column  e g  0x00000001000effdc in the example below   Just under the backtrace  in the  Binary Images  section  note the image name  the architecture  e g  arm64  and load address  0x1000e4000 in the example below  of the binary image  e g  TheElements   Execute the following      atos -arch arm64 -o TheElements app dSYM Contents Resources DWARF TheElements -l 0x1000e4000 0x00000001000effdc - AtomicElementViewController myTransitionDidStop finished context    Authoritative source  https   developer apple com library content technotes tn2151  index html   apple ref doc uid DTS40008184-CH1-SYMBOLICATE WITH ATOS
