// Add actions
let action1 = PKAlertAction(title: "Action 1", style: .default) { action in

Customization
PKAlertController allows you to customize the appearance and behavior of your alerts and action sheets. Below are some of the customization options available:
Customizing Actions
You can customize the appearance of alert actions by using the attributes
property of PKAlertAction. Here is an example:
// Create an alert controller
let alertController = PKAlertController(title: "Alert", message: "Test message", preferredStyle: .alert)
// Create an action with custom text color and font
let customAction = PKAlertAction(title: "Custom Action", style: .default) { action in
// Handle custom action tap
}
customAction.attributes = [
.foregroundColor: UIColor.red,
.font: UIFont.boldSystemFont(ofSize: 16)
]
alertController.addAction(customAction)
// Present the alert controller
present(alertController, animated: true, completion: nil)
Styling the Alert Controller
You can customize the appearance of the alert controller by using the customize
closure. Here is an example:
// Create an alert controller
let alertController = PKAlertController(title: "Alert", message: "Test message", preferredStyle: .alert)
// Customize the alert controller
alertController.customize = { controller in
// Customize controller's appearance
controller.view.tintColor = .purple
controller.view.backgroundColor = .white
// ...
}
// Present the alert controller
present(alertController, animated: true, completion: nil)
