How to optimize Swift Concurrency MainActor isolation for heavy UI ??

Hey everyone,

I'm currently refactoring a complex iOS app to fully adopt Swift Concurrency (async/await). We handle a massive stream of real-time WebSocket data that needs to update a SwiftUI lazy grid layout.

To prevent UI freezing, we offload the data processing to a background actor. However, when passing the large array of model updates back to the @MainActor for rendering, we are noticing slight frames-per-second (FPS) drops on older iOS devices.

What are the best practices or optimization techniques on C-Sharp Corner to batch these updates, minimize MainActor context switching overhead, or use custom executors to keep the main thread completely butter-smooth?
