var isEmpty: Bool { get }Returns
true if the group has no pending tasks; otherwise false.
At the start of the body of a withThrowingTaskGroup(of:returning:body:) call, the task group is always empty.
It’s guaranteed to be empty when returning from that body because a task group waits for all child tasks to complete before returning.
