@yo113 I'm also getting the same error. Can you guide me that how to resolve it?
I delete the scan delegate and remove it from info.PList but its not a proper way. So can you guid that how to solve it?

backgroundView = UIView(frame: window!.frame)

Crash on this line in new version.

@SachK13 can you let me know the solution please. I'm stuck and not able to make my app live.
