What are performance tuning for Combine in Swift?

Performance tuning for Combine in Swift involves optimizing various aspects of reactive programming to ensure better efficiency and responsiveness in applications. Here are some key points to consider:

  • Use Combine's Built-In Operators Wisely: Familiarize yourself with Combine's operators like map, filter, and merge to compose your data flow in an efficient way.
  • Caching Results: Cache results of expensive computations or network calls to reduce repetitive processing.
  • Throttle and Debounce: Utilize throttle and debounce operators to limit the frequency of events processed, such as UI updates or network requests.
  • Use a Custom Scheduler: If default scheduling does not meet your performance needs, consider using a custom scheduler for finer control over the execution context.
  • Memory Management: Use weak references where necessary to prevent retain cycles and memory leaks in your Combine pipelines.
  • Reduce the Use of Subjects: Subjects can introduce complexity and performance overhead; prefer to use publishers and operators when possible.
