Show today,Yesterday on JSQMessagesViewController

write this code in method.

let message = messages[indexPath.row] 
if indexPath.row == 0 { 
return NSAttributedString(string: message.date.dateString(), attributes: [NSAttributedStringKey.font : UIFont.systemFont(ofSize: 13.0, weight: .bold)]) 

}else { 
let previousMessage = messages[indexPath.row - 1] 
if Calendar.current.isDate(previousMessage.date, inSameDayAs: message.date) { 
return nil 
}else { 
return NSAttributedString(string: message.date.dateString(), attributes: [NSAttributedStringKey.font : UIFont.systemFont(ofSize: 13.0, weight: .bold)]) 
} 
}



And copy this outside of your class


public extension Date { 

public func dateString (format: String = "dd MMM, yyyy") -> String { 
let formatter = DateFormatter() 
formatter.dateFormat = format 
return formatter.string(from: self) 
} 
}
