import UserNotifications
import FirebaseMessaging
    

class NotificationService: UNNotificationServiceExtension {
        var contentHandler: ((UNNotificationContent) -> Void)?
        var bestAttemptContent: UNMutableNotificationContent?
        override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
            self.contentHandler = contentHandler
            bestAttemptContent = (request.content material.mutableCopy() as? UNMutableNotificationContent)
            
            if let bestAttemptContent = bestAttemptContent {
                // Modify the notification content material right here...
                bestAttemptContent.title = "(bestAttemptContent.title) [modified]"
                
                contentHandler(bestAttemptContent)
            }
        }
        
        override func serviceExtensionTimeWillExpire() {
            // Referred to as simply earlier than the extension will probably be terminated by the system.
            // Use this as a chance to ship your "finest try" at modified content material, in any other case the unique push payload will probably be used.
            if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {
                contentHandler(bestAttemptContent)
            }
        }
    }
    extension UNNotificationRequest {
        var attachment: UNNotificationAttachment? {
            guard let attachmentURL = content material.userInfo["image_url"] as? String, let imageData = attempt? Information(contentsOf: URL(string: attachmentURL)!) else {
                return nil
            }
            return attempt? UNNotificationAttachment(information: imageData, choices: nil)
        }
    }
    extension UNNotificationAttachment {
        comfort init(information: Information, choices: [NSObject: AnyObject]?) throws {
            let fileManager = FileManager.default
            let temporaryFolderName = ProcessInfo.processInfo.globallyUniqueString
            let temporaryFolderURL = URL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(temporaryFolderName, isDirectory: true)
            attempt fileManager.createDirectory(at: temporaryFolderURL, withIntermediateDirectories: true, attributes: nil)
            let imageFileIdentifier = UUID().uuidString + ".jpg"
            let fileURL = temporaryFolderURL.appendingPathComponent(imageFileIdentifier)
            attempt information.write(to: fileURL)
            attempt self.init(identifier: imageFileIdentifier, url: fileURL, choices: choices)
        }
    }
