Внедрить протокол Swift в Котлин
As of now, K/N requires many extra methods when implementing an
Objective-C or Swift protocol. Subclassing NSObject removes this
requirement
class Foo: BarProtocol
// Override BarProtocol methods and all NSObject methods
class Foo: NSObject(), BarProtocol
//Only need to override BarProtocol's methods
