Resymbolication in Xcode 6.1
- Get the crash report from Device via Xcode
- From the crash report get the version of the app.
- Get the IPA and dSYM file for the version from ios-ci.
- Put the following in a common folder (named lets say XYZ, which should not be in /tmp):
- The unsymbolicated crash report.
- The binary extracted from the IPA.
- The dSYM file for the related binary.
- On the terminal now, execute the following command:
DEVELOPER_DIR=`xcode-select -print-path` /Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources/symbolicatecrash -v -o resymbolicated.crash crashreport.crash Talkto.app.dSYM - This should symbolicate your crash report and export the unsymbolicated version to
resymbolicated.crash
Possible error case:
The whole file might not get symbolicated even with a successful run.The verbose output in that case should end with something like:
Running /Applications/Xcode.app/Contents/Developer/usr/bin/atos -arch armv7 -l 0x91000 -o '/Users/ayushgoel/Downloads/11/Talkto' 0x001a3d44 0x0034f262 0x001188be 0x0031d23a 0x000978e2 Here symbolication of only 5 addresses has been tried. But in the crash report there are more addresses, which needed to be symbolicated. See code below.

To fix this convert:
