You'll need to Symbolicate your Build to understand your Crash.
To do this in Crashlytics: you must add a "New Run Script Phase". this is the "+" Sign on the Build Phases of your target.
The Script goes like this:
"${PODS_ROOT}/Fabric/run" {YOUR-APP_ID_AT-FABRIC}
If you Installed Fabric using PODS.
Hope this helps ;-)
