I am fairly new to coding in general and really new to Xcode (Swift). I understand that I need to register a nib or a class but I don\'t understand \'where or how?\'.

I ran into this message when UITableView in the IB was moved into another subview with Cmd-C - Cmd-V.
All identifiers, delegate methods, links in the IB etc. stay intact, but exception is raised at the runtime.
The only solution is to clear all inks, related to tableview in the IB (outlet, datasource, delegate) and make them again.
