Exception when including Unity project as iOS framework

I have tried including an unity project as a framework inside an iOS project. However, I run into Bad access error : Thread 1: EXC_BAD_ACCESS (code=1, address=0x40) ![alt text][1] [Here][2] is the GitHub repo containing framework code and the code integrating the framework. How do I solve this issue? Also, has anyone accomplished importing unity as static library or framework into some other iOS project? Kindly guide me on how to proceed. Unity version : 2017.3.1f1 Xcode version : 9.2 [1]: /storage/temp/113787-screen-shot-2018-03-23-at-114446-am.png [2]: https://github.com/vedavi/UnityiOSFramework
