BaseChannelDelegate

@objc(SBDBaseChannelDelegate)
public protocol BaseChannelDelegate

An object that adopts the BaseChannelDelegate protocol is responsible for receiving the events in the channel. Delegate methods in BaseChannelDelegate are common for the BaseChannel. Exclusive delegate methods for OpenChannel and GroupChannel can be found in OpenChannelDelegate and GroupChannelDelegate. You must use OpenChannelDelegate and GroupChannelDelegate instead of using BaseChannelDelegate by using add(_:identifier:) in SendbirdChat.

Warning

If the object that adopts the BaseChannelDelegate protocol is invalid, the delegate has to be removed by the identifier via removeChannelDelegate(forIdentifier:) in SendbirdChat.
