Answer 1

I had a similar problem.

iPhone ReportCrash[567] : task_set_exception_ports(B07, 400, D03, 0, 0) failed with error (4: (os/kern) invalid argument)

I tried this to solve my problem and it worked fine.

Go to your Project > Build Settings > Search per Swift Compiler > in Optimization Level > set Debug and Release to None[-Onone]

Good luck.
