Create a simple Alert in swift

Question

It looks like alertstatus cannot be used in swift.

Can you guys please help me implementing an alternative solution to the code below?

  [self alertStatus:@"Message!" :@"Alert title" :0];

Answer 1

XCODE 10, IOS 12 And Swift 4 and above :

1. simple alert view with no action on buttons in an alert.

let alert = UIAlertController(title: "Error", message: "Something Went Wrong", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "Ok", style: .default))
self.present(alert, animated: true)

2. Alert with actions on ok and cancel button:

let refreshAlert = UIAlertController(title: "Punch Out", message: "You Will Will Punch Out", preferredStyle: UIAlertController.Style.alert)
        
refreshAlert.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action: UIAlertAction!) in
            print("Handle Ok logic here")
   }))
        
refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (action: UIAlertAction!) in
            print("Handle Cancel Logic here")
            refreshAlert .dismiss(animated: true, completion: nil)
   }))

    self.present(refreshAlert, animated: true, completion: nil)
