Answer 1

In viewWillAppear method of your menu items controller, Just create an overlay button on the front view and set action to revealToggle: of revealViewController

-(void)viewWillAppear:(BOOL)animated 
{
    [super viewWillAppear:animated];
    overlayView = [UIButton buttonWithType:UIButtonTypeCustom];
    overlayView.frame = self.revealViewController.frontViewController.view.bounds;
    overlayView.backgroundColor = [UIColor colorWithWhite:0.5 alpha:0.8];
    overlayView.tag = 999;
    [overlayView addTarget:self.revealViewController action:@selector(revealToggle:) forControlEvents:UIControlEventTouchUpInside];
    [overlayView addTarget:self.revealViewController action:@selector(revealToggle:) forControlEvents:UIControlEventTouchDragOutside];
    [self.revealViewController.frontViewController.view addSubview:overlayView];
}

In revealTogglle method remove the overlay button if any:

- (void)revealToggleAnimated:(BOOL)animated
{
    UIButton *overlayView = (UIButton*)[self.view viewWithTag:999];
    if (overlayView) {
        [overlayView removeFromSuperview];
        overlayView = nil;
    }
    // rest of the code...
}

Consider following solution, works perfect

private let DimmingViewTag = 10001

extension UIViewController: SWRevealViewControllerDelegate {    

    func removeInteractionFromFrontViewController() {

        revealViewController().delegate = self

        view.addGestureRecognizer(revealViewController().panGestureRecognizer())
    }

    //MARK: - SWRevealViewControllerDelegate

    public func revealController(revealController: SWRevealViewController!, didMoveToPosition position: FrontViewPosition) {

        if case .Right = position {

            let dimmingView = UIView(frame: view.frame)
            dimmingView.tag = DimmingViewTag

            view.addSubview(dimmingView)
            view.bringSubviewToFront(dimmingView)

        } else {
            view.viewWithTag(DimmingViewTag)?.removeFromSuperview()
        }
    }
}

Simple usage in UIViewController:

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    removeInteractionFromFrontViewController()
}

Another way is to have an overlay view when the rear view is revealed. You can use this updated library https://github.com/NSRover/SWRevealViewController and make sure you include shouldUseFrontViewOverlay = true when the rear view is revealed.
