 The library uses [Reachability](https://github.com/ashleymills/Reachability.swift) to attempt to detect network degradation events that lead to disconnection. If this is detected then the library will attempt to reconnect (by default) with an exponential backoff, indefinitely (the maximum time between reconnect attempts is, by default, capped at 120 seconds). The value of `reconnectAttemptsMax` is a public property on the `PusherConnection` and so can be changed if you wish to set a maximum number of reconnect attempts.

+If the Pusher servers close the websocket, or if a disconnection happens due to network events that aren't covered by Reachability, then the library will still attempt to reconnect as described above.
 
 All of this is the case if you have the client option of `autoReconnect` set as `true`, which it is by default. If the reconnection strategies are not suitable for your use case then you can set `autoReconnect` to `false` and implement your own reconnection strategy based on the connection state changes.

 We recommend that you use an authentication endpoint over including your app's secret in your app in the vast majority of use cases. If you are completely certain that there's no risk to you including your app's secret in your app, for example if your app is just for internal use at your company, then it can make things easier than setting up an authentication endpoint.
