# Messaging

Messaging is one of the core features of CometChat. We've thoughtfully created methods to help you send, receive and fetch message history.

At the minimum, you must add code for [sending messages](/sdk/ios/3.0/send-a-message) and [receiving messages](/sdk/ios/3.0/receive-a-message).

Once you've implemented that, you can proceed to more advanced features like [typing indicators](/sdk/ios/3.0/typing-indicators) and [delivery & read receipts](/sdk/ios/3.0/delivery-read-receipts).
