Does dispatching to a queue that's owned by an object retain that object? [duplicate]

Question

Suppose I have a simple call dispatch_async(self.queue, ^{ /* Empty */ }), where self.queue is a queue created previously.

Does self get retained by the Block in this case, given that there is no self reference inside the block, but only as a parameter for dispatch_async()?

Answer 1

Ok, so apple docs states that

The queue is retained by the system until the block has run to completion.

So the queue will be retained by the system until the block completes the execution, but the self won't be retained in this case.

Thanks to @Wain for pointing out my mistake in the previous version of this answer.
