Dynamically filter app feed based on slide-out menu item selected

I have a prototype of an app that contains a feed UITableViewController.

The data to populate this feed comes from my model where I defined a Feed class that I pre-populate using the following data structure:

NSArray* data = @[@{const1:@"NSString1 for const1", const2:@"NSString1 for const2"},@{const1:@"NSString2 for const1", const2:@"NSString2 for const2"}, ..., @{const1:@"NSStringN for const1", const2:@"NSStringN for const2"}]; (total of N pairs of (const1, const2))

I created a slide-out menu view controller that is dynamically populated based on my data model as well. As such I defined a slideOutMenuItems class that I also pre-populate using the following data structure:

NSArray* data = @[@"MenuItem1", @"MenuItem2", @"MenuItem3",... @"MenuItemP"]; (Total of P menu items)

When a menu item is selected by the user from the slide-out menu, I want to dynamically pass the menu item string (@"MenuItemM" if row number M is tapped on by the user) to filter out my feed based on matching the const1 NSString component of my feed array with the @"MenuItemM" NSString.

For that, in my slide-out menu view controller, in the prepareforsegue method, I have attempted the following:

• (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

  // Pass string based on SlideOutMenu cell selected to filter out feed

  if([segue.identifier isEqualToString:@"Filter_MenuItem"]) {
      FeedVCTableViewController* flameVCTableViewController = (FeedVCTableViewController*) segue.destinationViewController;
      NSIndexPath* indexPath = [self.tableView indexPathForCell:sender];
      NSString *menuItem = [self.slideOutMenuItems menuItemAtIndex:indexPath.row];
      NSPredicate *pred =[NSPredicate predicateWithFormat:@"name beginswith[c] %@", menuItem];
      flameVCTableViewController.feed = [[Feed prepopulatedFeed] filteredArrayUsingPredicate:pred];
  
  }
  

}

But I get the following error message on the last line of code above:

"No visible @interface for Feed declares the selector filteredArrayUsingPredicate".
