use #objc func to place a empty array of imageViews - arrays

Question

I want to use my swift code to place a imageview everytime the func moveRight is called. I want each new imageView to be separated by a 50 on the y axis. Right now my code compiles but nothing is changing when the function is called. But in the debug area I am seeing the count increasing.
import UIKit
class ViewController: UIViewController {
var myArray = [UIImageView]()
var bt = UIButton()
var count : Int = 0
override func viewDidLoad() {
super.viewDidLoad()
self.view.addSubview(bt)
bt.backgroundColor = UIColor.systemOrange
bt.frame = CGRect(x: view.center.x - 0, y: view.center.y , width: 50, height: 50)
bt.addTarget(self, action: #selector(moveRight), for: .touchUpInside)
}
#objc func moveRight() {
print("Yes")
myArray.forEach({
$0.backgroundColor = UIColor.systemTeal
self.view.addSubview($0)
})
var ht = 50
myArray.insert(UIImageView(), at: count)
print("Your Count is ", count)
myArray[count].frame = CGRect(x: view.center.x - 0, y: view.center.y + CGFloat(ht), width: 50, height: 50)
count += 1
ht += 50
}
}

Answer 1

You need to move the ht variable outside the moveRight() method.
Currently every time you run the method you recreate the variable and set it's initial value to 50, and then use that to set your location.
You need to do
class ViewController: UIViewController {
var myArray = [UIImageView]()
var bt = UIButton()
var count : Int = 0
var ht = 50 //initialise it here, then update it in the moveRight() method
//etc
and then remove the equivalent line from the method.
