How to show message date in JSQMessagesViewController

Question

I am trying to make a chat app and I am using JSQMessagesViewController library. My Chat View show all the messages with their date and time but I am facing some little bit of problem with this library. My problem is I wanna show message date only Once. Suppose: Yesterday date contains 10 messages and today date contains 15 messages

and I wanna show Only single date of these messages as not repeat dates for every messages

Well you need to determine if the message is the first of that day. Then return nil for all the others till a new day.

I created a function to determine if my message was the first sent by that individual. It looks like this

func firstMessageOfTheDay(indexOfMessage: NSIndexPath) -> Bool { 
  let messageDate = messages[indexOfMessage.item].date
  guard let previouseMessageDate = messages[indexOfMessage.item - 1].date else {
    return true // because there is no previous message so we need to show the date
  }
    let day = Calendar.current.component(.day, from: messageDate)
    let previouseDay = Calendar.current.component(.day, from: previouseMessageDate)
    if day == previouseDay {
        return false
    } else {
        return true
    }
}

Then call that in the appropriate function. Hope that helps let me know if you have any other questions.
