I am trying with learning Swift and got stuck on an issue here.

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var diceImageView1: UIImageView!

@IBOutlet weak var diceImageView2: UIImageView!

var leftDiceNumber=1

override func viewDidLoad() {
    super.viewDidLoad()
    
    // Do any additional setup after loading the view.

    diceImageView1.image = UIImage(imageLiteralResourceName: "DiceSix")

    // change transparency with diceImageView1.alpha=0.7

        }

@IBAction func rollButtonPressed(_ sender: UIButton) {
    print("button pressed")
    diceImageView1 = [ UIImageView(imageLiteralResourceName: "DiceOne"),UIImageView(imageLiteralResourceName: "DiceTwo"),UIImageView(imageLiteralResourceName: "DiceThree"),UIImageView(imageLiteralResourceName: "DiceFour"),UIImageView(imageLiteralResourceName: "DiceFive"),UIImageView(imageLiteralResourceName: "DiceSix")],[leftDiceNumber]
    
    leftDiceNumber=leftDiceNumber+1
  
}

}

But all I get is the error messages on the IBAction:

1.Argument passed to call that takes no arguments

2.Cannot assign value of type ‘[UIImageView]’ to type ‘UIImageView’

3.Consecutive statements on a line must be separated by ‘;’

4.Expected expression

What’s the difference between UIImageView and UIImage ? When they should be used?

Many Thanks in advance !
