How to enable logging
By default the PubNub SDK keeps logs in
pubnub.log located in the script direcotry. You can pass a custom logger as
:logger parameter during initialization of the client.
Always set the
UUID to uniquely identify the user or device that connects to PubNub. This
UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the
UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.
