                                                use_frameworks!

pod “PCLBlurEffectAlert”

import


                                              
                                                import PCLBlurEffectAlert

Initialize

UIBlurEffect


                                              
                                                // Default effect: UIBlurEffect(style: .extraLight)

.destructive: UIFont.boldSystemFont(ofSize: 20),

.cancel: UIFont.systemFont(ofSize: 14)])
// Adds ImageView

alertController.addImageView(with: <image files>)
// Adds TextField

alertController.addTextField()
// Adds actions

let action = PCLBlurEffectAlertAction(title: “I’m fine.”, style: .default) { _ in }
