What Is a Suspension Point In Swift?
A suspension point doesnβt mean the current thread is blocked. Nor it means the current actor is blocked. All it means is that the current task / function is blocked / suspended / waiting for an asynchronous task to finish. @MainActor func foo() async { doA() let b = await doB() doC() } When you get to doB(), then the MainActor / Main Thread are not suspended. Other tasks can be enqueued and executed on the main thread....
