Swift 4 array images show with food loop - arrays

Question

This is my code in swift 4 xcode. i have problems with my code. I can't show my array, with images on the simulator what things I'm doing wrong?
im a beginner in swift. and i have tried too look up how you write an array with images with four loop but the simulator docent show
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let img : UIImage = UIImage(named: "owl")!
let imageView = UIImageView(image: img )
self.view.addSubview(imageView)
// var images = Array<UIImage>()
//images.append(UIImage(named: "lion")!,
let ImgArray = ["lion.png","wolf.png","snake.png"]
var images = [UIImage]()
for i in 0..<ImgArray.count
{
images.append(UIImage(named: ImgArray[i])!)
}
let imageView2 = UIImageView(image: img )
self.view.addSubview(imageView2)
}
}

As explained by #Robert, instead of using the index of the array, you can use a for loop this way :
let imagesNames = ["img1.png", "img2.png", "img3.png"]
for imageName in imagesNames {
let image = UIImage(named: imageName)
images.append(image)
}
You can also use map to directly transform your array of images names to an array of images :
let imagesNames = ["img1.png", "img2.png", "img3.png"]
let images = imagesNames.map { UIImage(named: $0) }
where 0$ is your imageName.
