Sure, but I&#x27;d expect that Apple would provide some API for you to designate certain tasks as intended to be run in the &quot;Deep Background&quot;. With the understanding that such tasks are on a very short leash power and capability-wise, and may be arbitrarily cancelled—like iOS&#x27;s forcible app killing, but at a smaller grain. (Does GCD have a facility for the dispatcher to unilaterally do this already?)
