 @IBOutlet weak var tableView: UITableView!
 override func viewDidLoad() { 
super.viewDidLoad()

tableView.dataSource = self 
tableView.rowHeight = 80 
tableView.register(MyCell.self, forCellReuseIdentifier: "MyCell")   
websites.append(Website(title: "facebook.com", pictureLabel: "facelogo"))   
print(websites) } 
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
return websites.count } 
 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

Maybe you are not showing all the relevant code, because I cannot find any code to _append my custom object to aray_.

You may need to show more code and the exact line where the error happens.

Generally, when you get `Unexpectedly found nil`, you may need to check all the forced-something (`!`) in your code:

@IBOutlet weak var tableView: UITableView!

When `tableView` is nil, you get `Unexpectedly found nil` somewhere in your code at runtime.

You should better confirm the IBOutlet is surely connected, in several ways.

let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath) as! MyCell

When `

tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath)

` does not return a cell of type `MyCell`, your app crashes.

But, it seems very unlikely as your code has this line in an appropriate method:

tableView.register(MyCell.self, forCellReuseIdentifier: "MyCell")

---

Or your real code may have some flaws in the hidden parts. Please show all the relevant code in such a case.
