Finally found the obvious issue in my code. The delegate of the listener was not set. So not setting the delegate could be added to the "Common Mistakes" chapter of the https://www.objc.io/issues/14-mac/xpc/ article. On Sun, Aug 21, 2016 at 11:21 AM, Stephane Sudre <dev.iceberg@gmail.com> wrote:
I'm trying to implement the type of architecture described in the chapter "Anonymous Listeners and Endpoints" of https://www.objc.io/issues/14-mac/xpc/ .
Problem: --------
I'm facing a problem with the endpoint of the anonymous listener. Everything seems to work fine but calling a method of the remote proxy object using the provided endpoint of the anonymous listener does not work.
I've simplified the architecture to be able to find where the problem is but without any success:
1. Process A has a listener running using a mach service name. This works.
2. Process B connects to the mach service name and provides the endpoint of an anonymous listener to process A. This works.
3. Process A creates a connection to the anonymous listener using the provided endpoint. This works.
4. Process A gets a remote proxy object for the connection to B. This works.
5. Process A sends a message to the remote proxy object. Nothing happens.
I haven't found any useful piece of info on the developer forums (and I can't post on it).
I've checked the obvious stuff (the listeners and connections are resumed. There are no invalidation or interruption of the connections, the exported object is not dealloced).
So the reason why it's not working is a mistery so far. I could still be missing something obvious but I haven't seen it when running the code step by step.
OS X 10.10.5
Question: ---------
- Are anonymous listener working? I haven't found a single sample code on Apple website or elsewhere.
- Would there be some debug flags or hidden (global) defaults that would provide more debugging info about XPC communications (or lack thereof)
