According to this page here if you have proper application binary and .dSYM file then it is easy to symbolic them. But where are .dSYM and application binary files located?<
I just want to share something from my experience. Every time when I release a new version of my framework I save its dSYM in a separate folder. So, later I can find the relevant dSYM easily when I need it. It could be easily done by adding this line of code to the bash script in Build Settings (e.g. in this example I'm saving it to the desktop).
cp -r "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${FRAMEWORK_NAME}.framework.dSYM" "${HOME}/Desktop/${FRAMEWORK_NAME}.framework.dSYM"
