Swift 2 protocol extension not calling overridden method correctly

Question

I\'ve been running into an issue using Swift 2\'s protocol extensions with default implementations. The basic gist is that I\'ve provided a default implementation of a proto

To simplify my lack thereof understanding what the word "Yet" means in a non-specific error. I figured out, that I can't seem write a function with arguments, in overriding extended function, and the compiler gives me an error like this, but if I write a simple function with no arguments, and make a custom implementation and call it with my overridden "simple function" It works:

import Foundation
import UIKit

extension UIViewController {

    func slideInView(direction: Direction = Direction.LEFT, duration: CFTimeInterval = 0.5, closure:()->() ) {

        let animation               = CABasicAnimation(keyPath: "transform.translation.x")
        animation.fromValue         = self.view.bounds.width
        animation.toValue           = 0
        animation.duration          = 0.3
        animation.fillMode          = kCAFillModeForwards;
        animation.removedOnCompletion = false

        UIView.animateWithDuration(0.6, delay: 0.0, options: UIViewAnimationOptions.CurveEaseOut, animations: {
            self.view!.layer.addAnimation(animation,forKey:nil);

            }, completion: {(finished) -> () in
                closure()
        });
    }

    func slide()  {
        self.slideInView(.LEFT,duration: 0.66) {
            print("Slide in Left Complete")
        }
    }
}

class OtherUIViewController: UIViewController {



    override  func slide() {
        self.slideFromBottom(.BOTTOM,duration: 0.66) {
            print("Slide in Bottom Complete")
        }
    }

    func slideFromBottom(direction: Direction = Direction.BOTTOM, duration: CFTimeInterval = 0.5, closure:()->() ) {

        let animation               = CABasicAnimation(keyPath: "transform.translation.y")
        animation.fromValue         = self.view.bounds.height
        animation.toValue           = 0
        animation.duration          = 0.3
        animation.fillMode          = kCAFillModeForwards
        animation.removedOnCompletion = false

        UIView.animateWithDuration(0.6, delay: 0.0, options: UIViewAnimationOptions.CurveEaseOut, animations: {
            self.view!.layer.addAnimation(animation,forKey:nil);

            }, completion: {(finished) -> () in
                closure()
        });
    }
}
