Help me Debug a RunTime Error with CoreData in Swift 3 iPhone & Fix It

I need an expert in the new Swift 3 to help me with my project code. I was attempting to convert from Swift 2 to 3 but am getting a strange runtime error regarding Core Data in which duplicate results are being created somehow and I have no idea why. I'm a seasoned iPhone developer myself having made many apps but I'm stuck on this one. You can see the full details of the error on stackoverflow here ([url removed, login to view])

I've solved some of the issues but the nil error as a result of blank coredata objects being created is something I can't figure out. Any ideas are appreciated and of course I'll make it worth your while for helping me solve the issue.

I usually work with developers long term so expect other consulting type jobs in the future for iPhone etc.

This is probably a really simple fix for the right person. I am willing to pay $60 for the fix, so I would pay an extra $30 bonus for the person that helps. Thanks!
