Summary:
So when I try to connect a UIGestureRecognizer's target-action to the handleGesture function I get an unrecognized selector exception. If I then add @objc to the function to try and use dynamic dispatch I get a compiler error: “Members of protocol extensions cannot be declared @objc”

I would think this should be supported as the work around I posted on the forums seems absolutely unnecessary.

Relevant code:
 
protocol SomeProtocol: class {  
     func handleGesture(gesture: UILongPressGestureRecognizer)  
  
}  
extension SomeProtocol where Self: UITableViewController {  
    func handleGesture(gesture: UILongPressGestureRecognizer) { . . . }  
}  
 
class MasterViewController: UITableViewController, SomeProtocol {  
var gesture: UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: "handleGesture:")  

override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        tableView.addGestureRecognizer(gesture)
}
}

Expected Results:
Gesture should call the default implementation of handleGesture defined by the protocol extension.

Actual Results:
unrecognized selector exception
