Swift -Does the Bonjour NSNetServiceBrowser have a peer limit larger then MCSession's 8?

Question

Using a MCSession, the session can only have 8 devices connected to it:

Sessions currently support up to 8 peers, including the local peer

I need way more than 8 peers. I came across this apple forums dev thread where someone asked a similar question and an Apple engineer named eskimo said that it can be achieved using NSNetService and its includesPeerToPeer flag or the Bonjour browser.

I've seen a bunch of people ask questions on how to get around the MCSession 8 peer limit but I haven't seen anyone recommend what eskimo recommended. I also haven't found any blog posts with sample code to support what he said. His answer was posted on 6/5/19 so it's very recent.

If this is possible what is the peer limit if there is one?

I think they are suggesting that you build your own discovery service using Bonjour. The number of peers would then only be limited by your own code. – Melodiemelodion

@Banal I didn’t understand why this got downvoted. I think it’s a legit question especially since so many people ask how to get around the MCSession 8 peer limit. I have only found 1 Obj-C answers that leads you in the right direction but it’s still in Obj-C not Swift. This questions let’s others know that there are other ways to do achieve other then MCSession. – Egestion

I didn't downvote it. However it's not really a coding question. It's about library or offsite code or big picture stuff and those aren't well suited for this site. And I referred you to a site that is probably better for a question like yours. The downvote was probably to discourage people from wasting time on your question stackoverflow.com/help/how-to-ask – Banal

For what ever it's worth, Lance, I bumped into your question while working the Close Votes queue. Don't know why it ended up there. And I didn't vote to close it myself. – Banal

@Banal I know you didn’t downvote it. It got downvoted 5 minute after I posted it yesterday. I was just asking your opinion because of what you said. I will say this though, @Paulw11’s comment gave me enough info to lead on path to building my own Bonjour service. Had he not said that I would’ve never had idea to do that. Even though it got downvoted it helped me tremendously. I understand the coding part but I always saw it has as long as it helps a developer develop that’s what counts 🤷🏾‍♂️ – Egestion

That's why I didn't vote to close it. – Banal

@Banal thanks, I appreciate it. Happy Coding 😊😊 – Egestion

Answer 1

Using Bonjour there doesn't seem to be a limit. I found the answer here. eskimo insinuated the same thing.
