How do I reduce allocations and ARC overhead in Swift?

Reducing allocations and ARC (Automatic Reference Counting) overhead in Swift can significantly enhance your app's performance. By strategically managing memory and minimizing unnecessary object creation, you can optimize your application's responsiveness and efficiency.

Here are a few techniques to reduce allocations and ARC overhead in Swift:

• Use Value Types: Prefer using structs and enums over classes. Value types have lower memory overhead and are passed by value, avoiding reference counting.
• Minimize Object Creation: Reuse instances instead of creating new objects whenever possible, especially in loops or frequently called methods.
• Use Closures Wisely: Be cautious with closures that capture self. Use [weak self] to prevent strong reference cycles that can increase memory usage.
• Use Unmanaged Objects: In cases where you need to manage memory manually, consider using Unmanaged for certain performance-critical sections.
• Lazy Properties: Use lazy properties to defer the creation of an object until it is actually needed, reducing initial memory usage.

By applying these practices, you can effectively reduce allocations and the overhead caused by ARC in your Swift applications.
