Dispatchers Across Platforms

Choose dispatchers that exist on Android and iOS.

Where Work Actually Runs

A coroutine still runs on some thread. A dispatcher decides which thread or pool it uses, and that choice matters on each platform.

Use Dispatchers.Default for CPU-heavy work like parsing or sorting. It exists on Android and iOS, so shared code can rely on it.

withContext(Dispatchers.Default) { sort(data) }
