### Bugs
- Typographical error in the comment: "beeon" should be "been".

### Optimizations
- Consider using a date object (e.g., `Date`) instead of a string for `formattedDate` to make date manipulations easier and less error-prone.
- Documentation comments might benefit from additional details or a consistent format for future maintainability.
- Consider adding unit tests to validate the correctness and robustness of the code.

### Good points
- The code uses structures and extensions effectively to maintain clean separation of concerns.
- Adopting Swift protocols like `Hashable`, `Identifiable`, and `Sendable` helps in integrating with SwiftUI and concurrency features.
- Proper use of Swift's `Codable` for easy encoding and decoding of data structures.

### Summary
This piece of code is generally well-written and leverages Swift's powerful type system and protocols effectively. It has a strong separation between data representation and encoding/decoding rules, making it easier to manage and adapt. A minor issue with a typographical error in the documentation is present, but otherwise, the code is clean and efficient.
