AlertView Issue in iOS 13 Swift 4.2 - uialertview

Question

Here is my generic class which I'm using everywhere in my project but it's making issues on iOS 13,
i.e AlertView appear n automatically disappear before any option selection.
//var status = false
class AlertClass{//This is shared class
static let sharedInstance = AlertClass()
//Show alert
func alertWindow(title: String, message: String, completion:#escaping (_ result: Bool) -> Void) {
let alertWindow = UIWindow(frame: UIScreen.main.bounds)
alertWindow.rootViewController = UIViewController()
alertWindow.windowLevel = UIWindow.Level.alert + 1
let alert2 = UIAlertController(title: title, message: message, preferredStyle: .alert)
let defaultAction1 = UIAlertAction(title: "Yes", style: .destructive, handler: { action in
completion(true)
})
let defaultAction2 = UIAlertAction(title: "No", style: .destructive, handler: { action in
print("No")
completion(false)
})
alert2.addAction(defaultAction1)
alert2.addAction(defaultAction2)
alertWindow.makeKeyAndVisible()
alertWindow.rootViewController?.present(alert2, animated: true, completion: nil)
}
func alertOkWindow(title: String, message: String, completion:#escaping (_ result: Bool) -> Void) {
let alertWindow = UIWindow(frame: UIScreen.main.bounds)
alertWindow.rootViewController = UIViewController()
alertWindow.windowLevel = UIWindow.Level.alert + 1
let alert2 = UIAlertController(title: title, message: message, preferredStyle: .alert)
let defaultAction1 = UIAlertAction(title: "Ok", style: .default, handler: { action in
completion(true)
})
alert2.addAction(defaultAction1)
alertWindow.makeKeyAndVisible()
alertWindow.rootViewController?.present(alert2, animated: true, completion: nil)
}
func alertDialogWithImage(msg: String, Icon : UIImage?) {
let alertDialogWithImage = UIWindow(frame: UIScreen.main.bounds)
alertDialogWithImage.rootViewController = UIViewController()
alertDialogWithImage.windowLevel = UIWindow.Level.alert + 1
let alrt = UIAlertController(title: " ", message: msg, preferredStyle: .alert)
let cancel = UIAlertAction(title: "Ok", style: .destructive) { (action) in
}
alrt.addAction(cancel)
let subview = (alrt.view.subviews.first?.subviews.first?.subviews.first!)! as UIView
// subview.backgroundColor = UIColor(red: (145/255.0), green: (200/255.0), blue: (0/255.0), alpha: 1.0)
// alrt.view.tintColor = UIColor.black
alrt.view.tintColor = UIColor.red
let imageView = UIImageView(frame: CGRect(x: 120, y: 10, width: 35, height: 35))
imageView.image = Icon
alrt.view.addSubview(imageView)
alertDialogWithImage.makeKeyAndVisible()
alertDialogWithImage.rootViewController?.present(alrt, animated: true, completion: nil)
}
func alertWith3Actions(title: String, message: String, action1: String, action2: String, action3: String, completion:#escaping (_ result: Bool) -> Void) {
let alertWindow = UIWindow(frame: UIScreen.main.bounds)
alertWindow.rootViewController = UIViewController()
alertWindow.windowLevel = UIWindow.Level.alert + 1
let alert2 = UIAlertController(title: title, message: message, preferredStyle: .alert)
let defaultAction1 = UIAlertAction(title: action1, style: .destructive, handler: { action in
completion(true)
})
let defaultAction2 = UIAlertAction(title: action2, style: .destructive, handler: { action in
print("No")
completion(false)
})
let defaultAction3 = UIAlertAction(title: action3, style: .destructive, handler: { action in
print("Later")
completion(false)
})
alert2.addAction(defaultAction1)
alert2.addAction(defaultAction2)
alert2.addAction(defaultAction3)
alertWindow.makeKeyAndVisible()
alertWindow.rootViewController?.present(alert2, animated: true, completion: nil)
}
func alertTitleandMessage(title: String, message: String) {
DispatchQueue.main.async(execute: {
let alertTitleandMessage = UIWindow(frame: UIScreen.main.bounds)
alertTitleandMessage.rootViewController = UIViewController()
alertTitleandMessage.windowLevel = UIWindow.Level.alert + 1
let alert2 = UIAlertController(title: title, message: message, preferredStyle: .alert)
let defaultAction2 = UIAlertAction(title: "OK", style: .destructive, handler: { action in
})
alert2.addAction(defaultAction2)
alertTitleandMessage.makeKeyAndVisible()
alertTitleandMessage.rootViewController?.present(alert2, animated: true, completion: nil)
})
}
}
I have change my code like I define these function in UIViewController Extension but after that I'm unable to call them in UITableViewCell & UICollectionViewCell.
Your help n guidance will be much appreciated.
Thanks in advance.
