Help needed: Thread 1:signal SIGABRT

Hi

I'm updating a couple of old apps to Xcode 8.3 and I'm getting this error

Thread 1:signal SIGABRT

Any help would be greatly appreciated.

Thanks

Greg

This is the error code I'm getting

Seem you get the answer in the message :

Did you set a root view controller for the window ?
