Bugs

  • The userId conversion using Int(key) ?? 0 could default to a potentially unintended 0 if the conversion fails, which might mask underlying data issues.

Optimizations

  • Consider adding error handling or logging for Int(key) ?? 0 conversion to better manage unexpected data.
  • The Category enum values such as "subs" might benefit from more descriptive naming for clarity.
  • Instead of TimeInterval(check_time), use more descriptive conversion explanations or functions to improve code readability.

Good points

  • Usage of Swift's Hashable and Sendable protocols to ensure safety and future-proof the data structures.
  • Organized struct with clear separation between data handling and decoding, enhancing maintainability.
  • Proper utilization of Swift's raw strings in the enum declaration.

Summary

The code is well-structured and demonstrates good practices by leveraging Swift language features like Hashable and Sendable, ensuring a well-defined type-safe approach for handling user notifications. However, small improvements like error handling for the userId conversion and use of descriptive variable names can enhance robustness and readability.
