Get Group Chatrooms

Retrieves chatrooms and provides real-time updates using a Realm observer. This function allows users to fetch chatrooms and stay updated on any changes to the chatroom list.

Steps to get chatrooms with observer

1. Create an object that conforms to the HomeFeedClientObserver protocol.
2. Implement the required methods of the protocol in your object.
3. Call getChatrooms(withObserver:) function using the instance of LMChatClient.
4. Process the initial data and subsequent changes in your observer methods.

class MyChatroomObserver: HomeFeedClientObserver {
    func initial(_ chatrooms: [Chatroom]) {
        // Process initial list of chatrooms
    }

    func onChange(removed: [Chatroom], inserted: [(Int, Chatroom)], updated: [(Int, Chatroom)]) {
        // Handle changes to the chatroom list
    }
}

let observer = MyChatroomObserver()
LMChatClient.shared.getChatrooms(withObserver: observer)

note

This function uses a Realm observer to provide real-time updates. Make sure to keep a strong reference to your observer object to prevent it from being deallocated.
