Xcode Compile Error "expected method to read array element not found on object of type NSArray" [duplicate]

I am new to xcode, and I try to play with UITableView to show content in array.

I try to put some array inside Feed, and try to show them in table.

but the error is hinted at this instances

(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

on cell.textLabel.text = self.imageTitleArray[indexPath.row];

it says expected method to read array element not found on object of type NSArray

I am confused, why it wont read the array, captain obvious please help

this is my H files

#import <UIKit/UIKit.h>

@interface FeedTableViewController : UITableViewController
@property (strong, nonatomic) NSArray *imageTitleArray;
@end

and this is my M files

#import "FeedTableViewController.h"

@interface FeedTableViewController ()

@end

@implementation FeedTableViewController

{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
