Thread 1: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value

i am getting this error

can someone explain why its showing Five dots instead of four while doing opaq

I'm trying to do this, but since the course is from 2019, it's not the same now, can someone show how they did it?

Haha

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var diceImageView1: UIImageView!

/// <#Description#>
override func viewDidLoad() {
    super.viewDidLoad()
    
    diceImageView1.image = #imageLiteral(resourceName: "DiceSix")
    diceImageView1.alpha = 0.5
}

}

class ViewController: UIViewController {

@IBOutlet weak var diceImageView1: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()
   
    diceImageView1.image = #imageLiteral(resourceName: "DiceSix")
   diceImageView1.layer.opacity = 0.5
}

It works :)

}

The course is a nice course but it needs to be updated because Xcode has been updated and some features have changed.
