check out GitHub - davidstump/SwiftPhoenixClient: Connect your Phoenix and iOS applications through WebSockets! · GitHub if you are going for swift ios app.. it includes a basic example and link to more advanced ones…

personally I use phoenix channels for my ios/android apps - though I use react native - so I actually use the standard phoenix.js implementation - works great!

I run everything over the channels (except initial login that is a normal POST).. no issues, works wonderfully..

It works super great.

I use http(s) for the login and getting a token.

then phoenix.js is used in a class PhxService.

with a start function that takes the token and connects the websocket and two channels (user and public).

I have this in the join function:
Process.send_after(self(), :after_join, 10)

which then sends over all the data the app needs - which goes into the different redux reducers (or whatever they are called), so entire app is hydrated.

In PhxService you then have functions for making calls over the different channels, and getting response back, same for message received that then fires of redux-observable events.

this is of course an overview - I use rxjs and redux-observable to tame it all - but surely equally good and simpler solutions exists today.

Thanks for the response!
