isCancelled

Declaration

static var isCancelled: Bool { get }

Discussion

After the value of this property becomes true, it remains true indefinitely. There is no way to uncancel a task.

Interaction with Task Cancellation Shields

Cancellation may be suppressed by an active task cancellation shield (withTaskCancellationShield(operation:)), which may cause isCancelled to return false even though the task has been cancelled externally.
