Swift: How to make a UIAlertController
All apps have to interact with a user at one time or another. Ever since Swift 3, app developers must use the UIAlertController to accomplish this. Here’s an example of one that I use in my apps:

let title = “Pop-up Message Example”
let message = “This is an example of a pop-up message in Swift.”
let button = “Close”
let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertController.Style.alert)
alert.addAction(UIAlertAction(title: button, style: UIAlertAction.Style.default, handler: {(action:UIAlertAction!) in
}))
self.present(alert, animated: true, completion: nil)
}
When I make an UIAlertController, I like to organize it so I can quickly look at a block of code. This example will show a pop-up window with the title “Pop-up Message Example” and then show a message under it.
