Xcode 7 Swift 2 impossible to instantiate UIViewController subclass of generic UITableViewController

by

Unfortunately, generic Swift classes are not visible to Objective-C code and also are not supported in Interface Builder (in storyboards and xibs). I find these two points closely related.

As a solution I would suggest you to use aggregation: do not make you view controller generic, but extract some logic to another (generic) class and use it inside your view controller.
