Xcode UIButton to UITableView not connecting - ios

Question

I am designing a project where I want it to go to a table view when a button is clicked.
Here is a pic of the storyboard:Storyboard
Here is the code for the view with the button:
import UIKit
import os.log
class MealViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
//MARK: Properties
#IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var priceLabel: UILabel!
#IBOutlet weak var photoImageView: UIImageView!
#IBOutlet weak var ratingControl: RatingControl!
#IBOutlet weak var caloriesLabel: UILabel!
#IBOutlet weak var descriptionLabel: UILabel!
#IBAction func addToCart(_ sender: UIButton) {
}
and here is the table view code:
import UIKit
class CartTableViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 0
}
When I run it how it is, it opens a blank table. When I change the numberOfRowsInSection, it gives a sigabrt error. How can I get it to just open the view regularly?

Answer 1

The function numberOfRowsInSection define the count of rows in the given section. If you define 0 the table must be empty. If you define something else the table view asks for a concrete cell for each row by calling:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
Depending on your code thats the first place to look for the crash reason. Your code snipped doesn't show it.
