array of image literals getting "Type of expression is ambiguous without more context" in swift 5 - swift

Question

I am new to coding and am trying to learn Swift. I am making a simple "Rock Paper Scissors" app to practice using MVC.
I have an array (let imagesArray = [image literal, image literal, image literal]
when I have images array in the controller it works fine but when I try to move it to the model I get a "Type of expression is ambiguous without more context" error. Are image arrays not allowed in the model? my understanding is that data should be kept in the model so that's why I am trying to put it in there.
any thoughts would be much appreciated :)
struct GameBrain {
let images = [ #imageLiteral(resourceName: "rock"), #imageLiteral(resourceName: "paper"), #imageLiteral(resourceName: "scissors")]
func playGame() -> Int {
let choices = [0,1,2]
let choice = choices.randomElement()
return choice!
}
mutating func getWinner(choice: Int?) {
}
}
class ViewController: UIViewController {
var gameBrain = GameBrain()
#IBOutlet weak var imageViewLeft: UIImageView!
#IBOutlet weak var imageViewRight: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func goButton(_ sender: UIButton) {
imageViewLeft.image = images[gameBrain.playGame()]
imageViewRight.image = images[gameBrain.playGame()]
}
}

Answer 1

If you move images into the model you have to adjust the references
#IBAction func goButton(_ sender: UIButton) {
imageViewLeft.image = gameBrain.images[gameBrain.playGame()]
imageViewRight.image = gameBrain.images[gameBrain.playGame()]
}
Apparently the index is not needed so this is simpler
var playGame : UIImage {
return images.randomElement()!
}
and
#IBAction func goButton(_ sender: UIButton) {
imageViewLeft.image = gameBrain.playGame
imageViewRight.image = gameBrain.playGame
}
