There are two common causes for this:
a UUID mismatch between the crash report and the
Spotlight failing to index your
.dSYM(Xcode uses Spotlight to find the
.dSYMbased on its UUID)
You can check the former using
xcrun dwarfdump --uuid /path/to/your.dSYM.
$ mdls build/Debug-iphoneos/QTestbed.app.dSYM/ … com_apple_xcode_dsym_uuids = ( "F3D98D35-B43B-3A29-BDF0-8186AF886EDB", "94BF1D20-2A89-3E96-81BC-C46330D6932F" ) …
You can then run a UUID through
mdfindto confirm that Spotlight has the right info. For example:
$ mdfind 'com_apple_xcode_dsym_uuids == "F3D98D35-B43B-3A29-BDF0-8186AF886EDB"' /Users/quinn/DTS Work iOS/Samples and Tests/QTestbed-GIT/build/Debug-iphoneos/QTestbed.app.dSYM
