iOS App Crashes pointing to Crashed: com.twitter.crashlytics.ios.exception

Question

I am slightly confused, I am getting few crashes from my application where the crash logs has the following information too.

Crashed: com.twitter.crashlytics.ios.exception

Does this means that, its a crash from Fabric library or its a valid crash?

In the stack trace , there are some references to my application as well. Please check the following. The stacktrace points to "MYAPP" is pointing to my application.

Yes, it is a problem with the Crashlytics library, you should upgrade to a newer library. I changed from Crashlytics 3.14.0 to 3.12.0, and my problem was fixed.

  pod 'Fabric', '~> 1.10.2'
  pod 'Crashlytics', '~> 3.14.0'
