Instance Property インスタンスプロパティ

value

The result from a throwing task, after it completes.

Declaration 宣言 

var value: Success { get async throws }

Return Value 戻り値

The task’s result.

Discussion 解説

If the task hasn’t completed, accessing this property waits for it to complete and its priority increases to that of the current task. Note that this might not be as effective as creating the task with the correct priority, depending on the executor’s scheduling details. これはタスクを正しい優先度で作成するのと同じくらい効果的でないかもしれないことに注意してください、エグゼキュータのもつ予定の仕方の詳細に依存しています。

If the task throws an error, this property propagates that error. Tasks that respond to cancellation by throwing CancellationError have that error propagated here upon cancellation.
