Create a high priority serial dispatch queue with GCD
grand-central-dispatch, macos, objective-c
Solution
Create a serial queue, then use `dispatch_set_target_queue()` to set its target queue to the high priority queue.
Here's how:
dispatch_set_target_queue(myQueue, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0));
Now `myQueue` should run serially with high priority. Here's another SO answer if you want to know more.
Problem
How can I create a custom serial queue that runs at high priority? Right now I'm using `myQueue = dispatch_queue_create("com.MyApp.MyQueue", NULL);` but this doesn't seem to allow for setting a priority?
