isCancelled
A Boolean value that indicates whether the group was canceled.
Declaration
var isCancelled: Bool { get }Discussion
To cancel a group, call the TaskGroup.cancelAll() method.
If the task that’s currently running this group is canceled, the group is also implicitly canceled, which is also reflected in this property’s value.
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.
