BGTaskScheduler.Error.Code.immediateRunIneligible
A task scheduling error that indicates a task request didn’t run immediately due to system conditions.
Declaration
case immediateRunIneligibleDiscussion
The framework throws this error when a BGContinuedProcessingTaskRequest that your app submits with strategy set to BGContinuedProcessingTaskRequest.SubmissionStrategy.fail isn’t able to begin right away due to runtime conditions.
If the task that fails submission is of high importance and your app has other tasks submitted, you can try canceling the other task requests and resubmit the failed request.
