textField.layer.borderWidth = 0
}
alert.configureContentView { view in
view.titleLabel.textColor = UIColor.lightGrayColor()
view.titleLabel.font = UIFont.boldSystemFontOfSize(30)
view.messageLabel.textColor = UIColor.lightGrayColor()
view.messageLabel.font = UIFont.boldSystemFontOfSize(16)
view.textBackgroundView.layer.cornerRadius = 3.0
view.textBackgroundView.clipsToBounds = true
}
alert.addAction(AlertAction(title: "Cancel", style: .cancel))

Rounded button Alert View
let alert = AlertController(view: UIView(), style: .alert)
alert.contentWidth = 144
alert.contentCornerRadius = 72
alert.contentColor = .white
let action = AlertAction(title: "?", style: .cancel) { action in
}
alert.addAction(action)
action.button.frame.size.height = 144
action.button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 96)
action.button.setTitleColor(UIColor.red, for: .normal)
present(alert, animated: true, completion: nil)More customizable if you create a subclass
class CustomAlertController: AlertController {
override func addTextField(configurationHandler: ((UITextField) -> Void)? = nil) {
super.addTextField { textField in
textField.frame.size.height = 33
textField.backgroundColor = nil
textField.layer.borderColor = nil
textField.layer.borderWidth = 0
configurationHandler?(textField)
}
}
override func configureActionButton(_ button: UIButton, at style :AlertAction.Style) {
super.configureActionButton(button, at: style)
switch style {
case .ok:
button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 20)
button.setTitleColor(UIColor.gray, for: UIControlState())
case .cancel:
button.backgroundColor = UIColor.darkGray
button.setTitleColor(UIColor.white, for: UIControlState())
case .default:
button.setTitleColor(UIColor.lightGray, for: UIControlState())
default:
break
}
}
override func configureContentView(_ contentView: AlertContentView) {
super.configureContentView(contentView)
contentView.titleLabel.textColor = UIColor.lightGray
contentView.titleLabel.font = UIFont.boldSystemFont(ofSize: 30)
contentView.messageLabel.textColor = UIColor.lightGray
contentView.messageLabel.font = UIFont.boldSystemFont(ofSize: 16)
