Getting an NSException error. Looked around and it may be how I am calling the method but can't troubleshoot it, I'm a beginner so a good explanation is very much appreciated.

Here is my AddListingViewController.h 

```
#import <UIKit/UIKit.h>
#import "ListingTableViewController.h"
#import "ListingManager.h"

@interface AddListingViewController : UIViewController
@property (nonatomic) ListingTableViewController *manager;
@property (nonatomic) ListingManager *add;

@end

```

Here is my AddListingViewController.m

```
#import "AddListingViewController.h"

@interface AddListingViewController ()
@property (weak, nonatomic) IBOutlet UITextField *title;
@property (weak, nonatomic) IBOutlet UITextView *desc;
@property (weak, nonatomic) IBOutlet UITextField *price;

@end

@implementation AddListingViewController

@synthesize manager = _manager;
@synthesize add = _add;

- (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.manager = [[ListingTableViewController alloc] init];
    self.add = [[ListingManager alloc] init];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

    //cancel posting on tap
- (IBAction)cancelListing:(UIBarButtonItem *)sender {
    NSLog(@"cancel tapped thpugh");
    [self dismissViewControllerAnimated:YES completion:nil];

}

    //add item on tap
- (IBAction)addListing:(UIBarButtonItem *)sender {
    NSLog(@"Add button tapped");

    self.add.listingTitle = self.title.text;
    self.add.listingDescription = self.desc.text;
    self.add.listingPrice = self.price.text;

    [self.manager.listings addObject:self.add];

    [self dismissViewControllerAnimated:YES completion:nil];

}

@end

```

The error I am getting (I'm sure it says is clearly here but I don't know how to troubleshoot it)
