A new iOS feature needs a network result shared across several screens, and the UI has to update too. What role would you give each of Swift Concurrency's async/await, Task, and actor?
An async function is the syntax for writing waiting work like networking in order, a Task is the entry point from synchronous code (a button tap, viewDidLoad) into that async world, and an actor wraps mutable state that several Tasks touch together, like a response cache, and serializes access. UI updates happen in a ViewModel isolated to @MainActor.
