### Constants

[`NSBackgroundActivityScheduler.Result.finished`](/documentation/Foundation/NSBackgroundActivityScheduler/Result/finished)

The activity has finished executing. If the activity repeats, the next invocation is scheduled by the system.

[`NSBackgroundActivityScheduler.Result.deferred`](/documentation/Foundation/NSBackgroundActivityScheduler/Result/deferred)

System conditions have changed since the time the activity began executing, and deferral of additional work is recommended.
