Composable Multipeer Connectivity

[oliverepper]

Hi all!

I recently integrated the Multipeer Connectivity framework into a TCA app. Is there any broader interest for a library like composable-core-location or composable-core-motion? In that case I'd be happy to put some more work in. What I have now is rather minimal and just serves our own needs.

I've got a similar case for in app purchases. It works well and suits my needs and could definitely be built out with more features. I hope to find the time to start working on that soon.
I think the more feature packages we have the better!

It's not done and it's still rough but it serves as a demo. You can advertise, browse and send and receive an invite.

This looks great! What's the advantage of using MultipeerConnectivity over Network.framework, which can also be used for peer-to-peer as shown in this library? I was thinking of making my own composable-p2p-network wrapper. I feel like Network.framework is more maintained, more performant, and offers more customisation points, but I'd love to hear your thoughts.

Oh cool! I simply wasn't aware of other options. I'll check into this. I'd even be interested in something that could work on a Raspberry Pi, too. If maybe TCA can give up the Combine dependency in the future this would be interesting. If you want to start composable-p2p-network wrapper I'd be happy to check it out.

I've started implementing composable-P2P, I'd love for you to check it out! I've created the interfaces for the Listener, Browser, and Connection (check out the Network.framework documentation for more context), and I also implemented the Type-Length-Value protocol. I'm just not too sure about the structure composable-P2P should take – the Connection type is kind of like your Session type, but not exactly. Let me know what you think.

I've implemented composable-P2P which uses the Network framework instead of MultipeerConnectivity, let me know what you think. Had to do some pretty creative stuff to make it work with TCA's composable dependancy pattern 😅
