Can you help solve data.entry.init issue? - ios

Question

I'm getting the "thread 1: exc_bad_access (code=2, address=0x16fc0bfefe8) error. I have set up the iOS app to access a Table View Controller after logging in. It should display images. I have been following this tutorial http://shrikar.com/uitableview-and-uitableviewcell-customization-in-swift/ but no luck. This is my data.swift file where the error originates from:
import Foundation
class Data {
class Entry: Data {
let filename : String
init(fname : String) {
self.filename = fname
}
}
let products = [
Entry(fname: "placeholder1"), // <- Thread 1 error code shows in this line
Entry(fname: "placeholder2"),
Entry(fname: "placeholder3")
]
}
HomeTableViewController.swift
import UIKit
class HomeTableViewController: UITableViewController {
let data = Data()
override func viewDidLoad() {
super.viewDidLoad()
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 data.products.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! HomeTableViewCell
let entry = data.products[indexPath.row]
let image = UIImage(named: entry.filename)
cell.bkImageView.image = image
return cell
}
HomeTableViewCell.swift
import UIKit
class HomeTableViewCell: UITableViewCell {
#IBOutlet weak var bkImageView: UIImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
Humbly asking for some assistance. Thanks in advance.

Answer 1

The issue is this line:
class Entry: Data {
Since Entry inherits from Data when you create an instance of Data the program goes into an infinite loop of initializing both the first member of products (an Entry) and its parent class, Data. Instead it should be this, as per the tutorial:
class Entry {
