ios – PostingStyle of NotificationQueue

I’ve realized that when utilizing NotificationQueue to put up notifications, you may select a postingStyle. That is an enumeration with three important values: whenIdle, asap, and now.

Amongst them, now represents synchronous posting, which isn’t any totally different from utilizing the put up methodology of NotificationCenter.

My query is, each whenIdle and asap appear to depend on the Runloop to find out the timing of asynchronous posting. What situations ought to I take into account when deciding which asynchronous posting methodology is most applicable?

    public enum PostingStyle : UInt, @unchecked Sendable {

        
        case whenIdle = 1

        case asap = 2

        case now = 3
    }
