Along with crash report, I've .app and .dSYM package as well. I'm trying to symbolicate the crash report by running the following command

/Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash crash.crash > SymbolicatedPaperio.crash

The first few lines of exception stack trace looks like,

Last Exception Backtrace: 0 CoreFoundation 0x00000001898a61c0 0x189777000 + 1241536 1 libobjc.A.dylib 0x00000001882e055c 0x1882d8000 + 34140 2 CoreFoundation 0x00000001898a6094 0x189777000 + 1241236 3 Foundation 0x000000018a333808 0x18a285000 + 714760 4 UIKit 0x000000018f984848 0x18f6f1000 + 2701384 5 UIKit 0x000000018f9a4fac 0x18f6f1000 + 2834348 6 CoreFoundation 0x00000001898537dc 0x189777000 + 903132 7 CoreFoundation 0x000000018985140c 0x189777000 + 893964 8 CoreFoundation 0x0000000189780068 0x189777000 + 36968 9 paperio 0x00000001000b0d80 0x1000a4000 + 52608 10 paperio 0x00000001000bf0fc 0x1000a4000 + 110844 11 UIKit 0x000000018f768f3c 0x18f6f1000 + 491324 12 UIKit 0x000000018f987158 0x18f6f1000 + 2711896 13 FrontBoardServices 0x000000018b4365e8 0x18b413000 + 144872 14 Foundation 0x000000018a345794 0x18a285000 + 788372 15 BaseBoard 0x000000018b3b0f00 0x18b37e000 + 208640 16 FrontBoardServices 0x000000018b4306a8 0x18b413000 + 120488 17 FrontBoardServices 0x000000018b4363c4 0x18b413000 + 144324 18 UIKit 0x000000018f9885c0 0x18f6f1000 + 2717120 19 UIKit 0x000000018f988264 0x18f6f1000 + 2716260 20 UIKit 0x000000018fcb9ba4 0x18f6f1000 + 6065060

For the first line, on my mac, it is not symbolicated and the output remains same (as the non-symbolicated line above). However, on a different mac, I can see the output as:

0 CoreFoundation 0x00000001898a61c0 __exceptionPreprocess + 124

This is happening for all the frameworks and libraries. Want to understand what possibly could be missing on my mac - that its not symbolicating properly and how to fix this.

Basically, to symbolicate libraries and framework's method, we need to have symbols for the iOS version for which crash was generated. These are (by default) present in ~/Library/Developer/Xcode\iOS DeviceSupport. So, if the symbol for correct iOS version is not present here - the symbolicator would not be able to properly decrypt the reports.

You need to specify the location of the Archive file：

./symbolicatecrash crashPath archivePath > output
