MXLastMessage text and attributedText are always nil

[ob1vansk1y]

After start session I have tried to call all types of methods like session.fixRoomsSummariesLastMessage() also tried to reset it, but still those properties are always nil.

The only piece of code, that helped me to retrieve it is finding it by eventId. Could you, please tell the best way to retrieve it? Or what should be the correct flow of getting the room last message text

`private func getMessage() {
        session.event(withEventId: summary.lastMessage.eventId, inRoom: room.roomId) { response in
            guard let message = response.value?.content["body"] as? String else {
                self.lastMessageEvent = "No message"
                return
            }
            self.lastMessageEvent = message
        }
}`

Also, as a new user to Matrix SDK, with all respect to your team and developers, who left awesome comments in the project, I would like to ask you to improve the documentation for the SDK for iOS, since your repository is the only source of the information (except your comments on the code, which actually helped me a lot) and your console sample app is out of date and not supported and has not straightforward and easily understandable logic, which is really time consuming. It is not the best way to master your SDK for developers that way.
