7 years ago I wanted to clarify that, in the Symbolicated / Unsymbolicated examples above, the Symbolicated log is also only partially symbolicated:
1 Mapbox 0x0000000100409734 mbgl::DefaultFileSource::resume() + 24
2 Mapbox 0x0000000100409734 mbgl::DefaultFileSource::resume() + 24
3 Mapbox 0x00000001003c9c1c _hidden#8730_ + 24 (__hidden#8849_:59)The "_hidden" symbol in this particular case would've been:
3 Mapbox 0x00000001003c9c1c -[MGLOfflineStorage unpauseFileSource:] (MGLOfflineStorage.mm:59)

using xcode 10 Fabric crash reports.
while someother crash reports are very accurate. like below
Platform: iOS Mapbox SDK version: v3.4.2, v3.5.0-beta.3, v3.5.0-rc.1
Some crash reports are only partially symbolicating. Known affected versions of the SDK are listed, but this probably is not limited to those.
If the unsymbolicated crash report retains the unsymbolicated addresses, the dSYM for that version of Mapbox.framework can still be used to symbolicate. But, if the crash report comes from Apple via iTunesConnect/Xcode, the unsymbolicated addresses have been replaced with
_hiddenand the report cannot be symbolicated after the fact.Here’s the same crash, in different versions of the same TestFlight-distributed app, bitcode enabled, using different iOS SDK versions:
Symbolicated (v3.5.0-beta.2)
