How to add textField to AlertView? Let's keep it short and simple.

This works for Swift 3.0 and above.

var nameField: UITextField?
let alertController = UIAlertController(title: "Add Number", message: nil, preferredStyle: .alert)
// Add textfield to alert view
alertController.addTextField { (textField) in
    nameField = textField
}

First, you instantiate an object of UIAlertController and then you add a text field to it by accessing addTextField member of UIAlertController class.
