Key Points​

  • Lack of Cohesion: Avoid mapping network statuses directly to view statuses without clear logic, which can lead to maintainability issues.
  • Lazy Switch Cases: Be cautious when using the default clause in switch statements; it can hide unhandled cases and lead to unexpected behavior.
  • Assuming Raw Value Incrementation: Never rely on Swift's automatic raw value assignment for enums, as it can lead to fragile code.

Summary of Contents​

  • Lack of Cohesion When Mapping Values: Discusses the problem of mapping network statuses to view statuses without considering future changes and how to refactor the code to maintain cohesion.
  • Lazy Switch or Using Default Clause: Explains the pitfalls of using default clauses in switch statements and recommends explicitly handling each enum case.
  • Assuming Automatic Raw Value Incrementation: Warns against relying on Swift's automatic raw value incrementation for enums, advising developers to use explicit values to avoid bugs.
