I am having an issue with the UserNotifications framework only on M1 machines. The following function call crashes only on M1 but works fine for the same version of Xcode (13.2.1+) and iOS 15.2+: `try UNNotificationAttachment(identifier: "image", url: fileURL)` The full snippet is here: ``` private func attachment(for image: UIImage) -> UNNotificationAttachment? { guard let data = image.pngData() else { assertionFailure() return nil } let tempDirectory = URL(fileURLWithPath: NSTemporaryDirectory()) .appendingPathComponent("titan_notification_request_images", isDirectory: true) do { try FileManager.default.createDirectory(at: tempDirectory, withIntermediateDirectories: true, attributes: nil) let uniqueFilename = "\(image.hashValue).png" let fileURL = tempDirectory.appendingPathComponent(uniqueFilename) try data.write(to: fileURL) return try UNNotificationAttachment(identifier: "image", url: fileURL) } catch let error { assertionFailure() return nil } } ``` I get the following error message: “Unrecognized attachment file type” The other lines above do not throw any errors. Hope you can advise, thanks!
