Swift- EXC_CRASH (SIGABRT) how to find the exception with this stack trace

Question

swift - unable to decode the stack trace, how to find where the exception occurs

Does anyone know anything about this crash? That all the information here, I still don't know whats wrong about it. The important is that I found many crash contain this part, this is the stack trace that I have got here, the stack trace has no controller names or row numbers to begin with, its like a matrix of code
