"review": "8\n\n### Bugs\n- No significant bugs identified in this code snippet.\n\n### Optimizations\n- The id generation logic could potentially be simplified using string interpolation.\n- Consider using enum cases directly for type safety and clarity in decoding logic.\n- Mapping the raw type to Kind could be more exhaustive or safeguarded with a fallback or error handling if unknown values arise.\n\n### Good points\n- The structuring using nested enumerations and extensions leads to clear organization.\n- Conformance to Swift protocols like Hashable, Identifiable, Sendable, and Codable enhances usability and makes it versatile in different contexts.\n- The use of flatMap facilitates clean handling of optional values.\n- Utilization of descriptive comments for each aspect of the notification is helpful for understanding.\n\n### Summary\nThis code defines a Notification struct with complete interoperability, providing encoding and decoding functionality seamlessly. The struct is well-organized with clear enums and comments to provide context and functionality. It efficiently uses Swift's optional handling and protocol conformance to offer a robust, clear structure for representing user notifications.\n\n### Open source alternatives\n- SwiftNotificationBanner: A lightweight library to display notification bars in a customizable and quick manner.\n- Noty: A simple in-app notification framework inspired by iOS system notifications.\n- MessageKit: A community-driven replacement for JSQMessagesViewController that builds upon Apple's new UI elements for dealing with notifications.",
