I'm using sockets in android to have a connection between backend(node js) app and my android app.

I'm successfully able connect to socket by passing auth header like

 mSocket = IO.socket(uri, IO.Options().apply {
 // Pass the authentication details using 'auth'
 auth = mutableMapOf<String, String>(
 "api_key" to "key here",
 "app_id" to "os-dev"
 )
 })

Since backend is expecting in auth.

this is working fine for android but on ios swift i'm unable to do so. I don't want to switch to query params as i'll have to change backend code and that is not in my reach.

Does swift not at all support auth header?

there is another web and react native example with which i was able to successfully connect.

const socket = io('https://backend.com', {
 auth:{
 api_key:'dddasdas',
 app_id:"stidev"
 }
});

This works on web version of my app and in react native android as well
