Laravel Applications Invalid argument supplied for foreach() Errors

I am learning PHP Laravel and I am developing shopping cart project. I am able to add the product into list but, when I click shopping cart link. I am getting following error.

FacadeIgnitionExceptionsViewException Invalid argument supplied for foreach() (View: C:UsersKhundokar NirjorDesktoplaravel Tutorialshopping-cartresourcesviewsshopshopping-cart.blade.php)

Here is my Router

Route::get('/shopping-cart',[
    'uses' => 'ProductController@getCart',
    'as' => 'product.shopppingCart'
]);

Here is my header.blade.php code.

<nav class="navbar navbar-default">
    <div class="container-fluid">
        <!-- Brand and toggle get grouped for better mobile display -->
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">

                    <ul class="dropdown-menu">

                    @endif


                        <li role="separator" class="divider"></li>

                    </ul>

            </ul>
        </div><!-- /.navbar-collapse -->
    </div><!-- /.container-fluid -->

Here is my shopping-cart.blade.php

     <h2>No Items In Cart</h2>
     </div>
     </div>


     @endif
@endsection

Here is my controller code

public function getCart()
    {
        if(!Session :: has('cart') ){
            return view ('shop.shopping-cart');
        }
        $oldCart = Session::get('cart');
        $cart = new Cart($oldCart);
        return view ('shop.shopping-cart' , ['products' => $cart->items, 'totalPrice'=>$cart->totalPrice]);
    }

Here is screen shot when I clicked the shopping-cart link

Answer

Try like this

 @if(!empty($products) && count($products) > 0) 
     @foreach($products as $product)
       // your code here
     @endforeach // typo in foreach fixed
 @endif
