Swift Application Crashes 1-3 times in Distribution and starts working fine

Application goes as follows.In iOS8+ works fine. Issue is iOS7.1.2

1. Swift application, used deployment target 7.1. No internet connection(mostly closed network). Enterprise distribution
2. Have used objective-c files, so bridge is there.
3. Works fine in simulator and device when watchdog timer is not there.
4. In distribution, it waits for sometime and crashes. If taken again, it works.
5. Sometimes after installation starts working after 1st crash, sometimes after 2-3 crashes.
6. Once started, the application works fine without any issue.
7. If device is hard reset, the 4-6 steps repeat again.

The application hasn't even started and is crashing while loading libraries. I am providing the crashreport.
