Swift - method swizzling

This is the method swizzling code written in Objective-C. I am having a hard time converting this in Swift.

void MPApplicationDidRegisterForRemoteNotificationsWithDeviceToken(id self, SEL _cmd, UIApplication *application, NSData *deviceToken) {
    [[MPPush shared] appRegisteredForRemoteNotificationsWithDeviceToken:deviceToken];

    IMP original = [MPAppDelegateProxy originalImplementation:_cmd class:[self class]];
    if (original)
        ((void(*)(id, SEL, UIApplication *, NSData*))original)(self, _cmd, application, deviceToken);
}  

Swiftify isn't converting the above code correctly.

I tried to do this but I am not sure how to pass parameters and use the exact above parameters in Swift swizzling method. This is my fail attempt to convert the above in Swift (code doesn't even compile) :

var MPApplicationDidRegisterForRemoteNotificationsWithDeviceToken: Void {
        //     TODO:   MPPush.shared.app

        let original = MPAppDelegateProxy.proxyAppDelegate.originalImplementation(selector: cmd, forClass: type(of: self))
    }(self: Any, _cmd: Selector, application: UIApplication, deviceToken: Data)
