Dispatch Queues

  • Private Concurrent vs. Global Dispatch with say qos = .userInitiated
    I suppose with global . . . it will match concurrent activities with the hardware . . . ? Isn’t it “better” to leave things to whatever entity that takes care of it? As opposed to using a private concurrent queue? What’s the use case?
