GCD queue name to get / tag

Question

How to get the current queue name? I mean the signature in the queue, for example com.example.myqueue. In Xcode 4, in the debugger, I see only _block_invoke_1. Thanks.

Answer 1

What about dispatch_queue_get_label ?

Answer 2

In Objective-C, you can write the label of the current queue with:

 NSLog(@"%s", dispatch_queue_get_label(DISPATCH_CURRENT_QUEUE_LABEL)); 

In Swift (2.0):

 print(String(UTF8String: dispatch_queue_get_label(DISPATCH_CURRENT_QUEUE_LABEL))!)
