What difficulties can arise when using context within business logic in UseCase?

Using context within the business logic UseCase in iOS can lead to several challenges:

• Lifecycle and memory leaks: If the context contains references to UI components or other objects with limited lifetimes, improper management of references can cause memory leaks or crashes.

• Responsibility mixing: Business logic should be as independent as possible from platform-specific details. Injecting context (e.g., UIViewController or NSManagedObjectContext) can violate the separation of concerns principle and complicate testing.

• Testability: Dependence on context makes it harder to write unit tests, as it requires creating or mocking complex objects.

• Thread safety: If the context is not thread-safe, using it in business logic can lead to data races and errors.

Therefore, it is recommended to separate business logic from the context, passing only necessary data or abstractions to the UseCase to maintain architectural purity and ease maintenance.
