Question
As I am creating a TableView programmatically with multiple cell and in each cell having UICollectionView, UITableView, UITableView.... but I am not able to find the error and every time when I run the program it Shows " Command failed due to signal: Segmentation fault: 11".
Has any one created this type of UI using coding.
New in Swift so forgive for errors.

Answer
class MyViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
let tableView = UITableView()
override func viewDidLoad() {
super.viewDidLoad()
// Set the table view's frame
tableView.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height)
// Set the data source and delegate
tableView.dataSource = self
tableView.delegate = self
// Register the custom cell class
tableView.register(CustomTableViewCell.self, forCellReuseIdentifier: "CustomCell")
// Add the table view as a subview
view.addSubview(tableView)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomTableViewCell
cell.textLabel?.text = "Row \(indexPath.row)"
return cell
}
}
