Twilio developer evangelist here.

  1. In the iOS SDK you can update a message body using updateBody:completion and you can update message attributes with setAttributes:completion.

  2. To get the number of unread messages for a channel you can use getUnconsumedMessagesCountWithCompletion and for the total messages in a channel you can use getMessagesCountWithCompletion.

Let me know if that helps at all.

  • Is it necessary to set the Consumption Horizon, how woudl you do this anyway with the Swift API? Also @philnash what defines an unconsumed message? Currently I send messages to a channel and before opening up my chat window I check the channel for unconsumed messages, but it always say no messages even if I call setNoMessagesConsumedWithCompletion. I am using the Swift API...can you help? What do I need to do to find out how many messages in my channel have not been read yet? At what point do they become read? (when the user opens up a chat channel and requests to getLastWithCount? – Ben Smith Aug 19 '18 at 16:44
  • Hi @BenSmith. That's a lot of questions. I reckon most can be answered with a read through the [consumption horizon documentation](https://www.twilio.com/docs/chat/consumption-horizon). If you have a specific questions about something that isn't working, then I recommend asking a new question on Stack Overflow. – philnash Aug 21 '18 at 21:55
