kandi X-RAY | openrec Summary
OpenRec is an open-source and modular library for neural network-inspired recommendation algorithms. Each recommender is modeled as a computational graph that consists of a structured ensemble of reusable modules connected through a set of well-defined interfaces. OpenRec is built to ease the process of extending and adapting state-of-the-art neural recommenders to heterogeneous recommendation scenarios, where different users', items', and contextual data sources need to be incorporated.

QUESTION
When I present a view controller which has a picker in it through the method present(viewController(), animated: true, completion: nil)
, the error unexpectedly found nil while unwrapping an Optional value
is thrown. Can someone tell me how to fix this?

Yes, because when you do a segue you are using the view controller in the storyboard, where it has a view, and that view contains a picker view and all the outlets get hooked up.
But your createNew
creates a different view controller, one with an empty view containing no picker view or anything else. So your outlets are never hooked up, they are nil, and you crash.
You need to do what the segue does: pull out the view controller from the storyboard.
