Is it necessary to suspend/resume a dispatch queue/source on sleep/wake notifications?
Does anyone know if it is necessary to dispatch_suspend/resume a queue or source when sleep/wake notifications triggered in a macOS app?
I've read the docs and done some searching but couldn't find anything definitive other than the concurrency programming guide states that all timer dispatch sources are suspended when a computer goes to sleep. When the computer wakes up, they are woken up as well.
Thanks (sorry for the cross-post to Cocoa-Dev),
