To display the Alert message in your Swift 3 application you can use the following code
I am using UIAlertController
to show the message
let msg : String="How are you?" let alert = UIAlertController(title: "Hello", message: msg, preferredStyle: UIAlertControllerStyle.alert) self.present(alert, animated: true, completion: nil)
You can see the following alert window for the above code
If you want to add “OK” button for the alert window you can use the following code
let alert = UIAlertController(title: "Hello", message: msg, preferredStyle: UIAlertControllerStyle.alert) // add OK button alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler: nil)) self.present(alert, animated: true, completion: nil)
You will get the following alert window with “Ok” button
