Bugs

  • The JSONDecoder's dateDecodingStrategy set to .iso8601WithOptionalFractionalSeconds does not exist; it should be .iso8601. If a custom strategy for optional fractional seconds is needed, this needs to be implemented separately.

Optimizations

  • Consider adding error handling or logging to catch issues during JSON encoding/decoding.
  • If dateDecodingStrategy with optional fractional seconds is truly required, implement a custom decoding strategy.

Good points

  • Encapsulation of JSONEncoder and JSONDecoder configuration within static properties improves code reusability and centralizes configuration.
  • Use of the .iso8601 date encoding/decoding strategy aligns with a standardized format for date/time.

Summary

This piece of code provides a well-structured approach through extensions to configure JSONEncoder and JSONDecoder with ISO8601 date strategies, which are commonly used for APIs. The method for encoding is correctly standardized, but there's an issue with using a non-existent decoding strategy for handling optional fractional seconds. The structure itself is clean, maintains good practices for code reusability, and is set up for potentially easy maintenance. Adding error handling could catch configuration issues during actual encoding/decoding operations.
