SWRevealViewController insertObject:atIndex object cannot be nil - ios

Question

i'm a new developper with storyboard.i try to make a app with a slide-out menu.
To do this, i use the library : SWRevealViewController and the tutorial : http://www.appcoda.com/ios-programming-sidebar-navigation-menu/ .
i follow the tutorial, but i load the application, i'have this error :
Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '*** -[__NSArrayM
insertObject:atIndex:]: object cannot be nil'
my app crash on this line :
[self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];
how can i set self.revealViewController ?
here my storyboard UPDATED:
to understand my app, startviewController is used to download and store data, after downloading, the mainViewcontroller is showed.
i want my slide out menu on my mainviewcontroller, but i cant not do.
here the code i add to my mainviewController viewdidload :
- (void)viewDidLoad
{
[super viewDidLoad];
self.contentView.autoresizesSubviews = YES;
_sharedUser = [User sharedUser];
///slide out menu
// Change button color
//SWRevealViewController *revealViewController = [self.navigationController.storyboard instantiateViewControllerWithIdentifier:#"RevealViewController"];
_sidebarButton.tintColor = [UIColor redColor];
// Set the side bar button action. When it's tapped, it'll show up the sidebar.
_sidebarButton.target = self.revealViewController;
_sidebarButton.action = #selector(revealToggle:);
// Set the gesture
[self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];
//end slide out
self.contentView.backgroundColor = [UIColor cyanColor];
if (_sharedUser.tokenString) {
}
else{
[self showHomeWithoutLogginView];
}
}

I'm looking at the tutorial you are following. According to your screenshot, there are some stuff missing in your storyboard.
The RevealViewController should be connected with two controllers: a front viewController (for displaying content) and a rear viewController (for showing the navigation menu):

Those connections (segues) should be marked as "reveal view controller" and each of them have to be named accordingly: "sw_front" and "sw_rear".
Then you have to add the menu items in the navigation menu (rear view controller) and connect each cell to the corresponding viewController, give the segues a name and mark them as a SWRevealViewController class. You may want to connect the front view controller to the viewController you want to be shown first.
I strongly suggest you make the tutorial as it is. I think I used it in the past and it worked pretty well. If you have any doubt about it don't hesitate to ask.
Best of lucks!

Are you using the latest version of the SWRevealViewController? The AppCoda tutorial is outdated, and SWReveal has great sample on Git.
Check your segue identifier and class on your storyboard. Have you set sw_front and sw_rear? Also, in the latest version, your segue for setting the Menu / Front View should be: SWRevealViewControllerSegueSetController and not the old SWRevealViewControllerSegue.
EDIT:
Also note that calling [self.revealController panGestureRecognizer]; is enough to enable the gesture; no need for an additional gesture.
EDIT:
Try initializing like this:
MenuViewController *menuVC = [self.storyboard instantiateViewControllerWithIdentifier:#"MenuViewController"];
UINavigationController *frontNavigationController = [self.storyboard instantiateViewControllerWithIdentifier:#"MainNavigationController"];
SWRevealViewController *revealViewController = [[SWRevealViewController alloc] initWithRearViewController:menuVC frontViewController:frontNavigationController];
EDIT:
Can you try adding an action to your Menu Button like this:
[menuButton addTarget:self.revealViewController action:#selector(revealToggle:)
forControlEvents:UIControlEventTouchUpInside];
