Crashlytics not giving proper crash reports

Try this

1. Goto to Build Settings
2. then goto Build Options
3. In build options goto Debug Information Format
4. and Change Debug's DWARF to DWARF with DSYM File.

Now again follow Fabric crashlytics steps and you will definitely get the proper crash report.

I've not tried it, but I think by following the guidelines mentioned in Matt's answer you can resolve your query.
