    @IBOutlet weak var diceImageView1: UIImageView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        diceImageView1.image = #imageLiteral(resourceName: "DiceSix")
      
        //Who           What   Value
        diceImageView1.alpha = 0.5
    }


}

was great until i started the Alpha step , green background took over everything !?

@wellbegen In the document outline pane you can sort the layers of objects by dragging each object. It looks like you need to move the background image to the back so that the other objects are visible.

new challenge for rolling to dice 2 successfully completed!

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.
