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,

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.
