Text bubbles do not appear!

[Noah-Ksk]

Hi. I want to use messageKit to implement a chat section in my app. I set the interface like this below but when I pushed textingVc I can not see the text bubbles. I can monitor the other properties like textbar and send button etc. Here is my code block

`
import UIKit
import MessageKit

struct Sender : SenderType {
var senderId: String
var displayName: String
}

struct Message : MessageType {
var sender: SenderType
var messageId: String
var sentDate: Date
var kind: MessageKind
}

struct Media: MediaItem {
var url: URL?

var image: UIImage?

var placeholderImage: UIImage

var size: CGSize

}

class TextingVC: MessagesViewController, MessagesDataSource, MessagesLayoutDelegate, MessagesDisplayDelegate, MessageLabelDelegate {
var currentSender: SenderType = Sender(senderId: "self", displayName: "Noah")

/*var currentSender: SenderType {
    return Sender(senderId: "self", displayName: "Noah")
}*/
var otherSender: SenderType {
    return Sender(senderId: "other", displayName: "Unknown")
}
var messages : [Message] = []

override func viewDidLoad() {
    super.viewDidLoad()
    
    
    messages.append(Message(sender: currentSender,
                            messageId: "1",
                            sentDate: Date(),
                            kind: .photo(Media(url: nil, image: UIImage(named: "ikon"), placeholderImage: UIImage(named: "ikon")!, size: CGSizeMake(200, 200)))))
    messages.append(Message(sender: otherSender,
                            messageId: "2",
                            sentDate: Date(),
                            kind: .text("Some examples here")))
    messages.append(Message(sender: currentSender,
                            messageId: "3",
                            sentDate: Date(),
                            kind: .text("Its gonna work?")))
    messages.append(Message(sender: otherSender,
                            messageId: "4",
                            sentDate: Date(),
                            kind: .text("some words !")))
    messages.append(Message(sender: currentSender,
                            messageId: "5",
                            sentDate: Date(),
                            kind: .text("finally")))
    
    messagesCollectionView.messagesDataSource = self
    messagesCollectionView.messagesLayoutDelegate = self
    messagesCollectionView.messagesDisplayDelegate = self
    
}
func textColor(for message: any MessageType, at indexPath: IndexPath, in messagesCollectionView: MessagesCollectionView) -> UIColor {
    return .red
}


func messageForItem(at indexPath: IndexPath, in messagesCollectionView: MessageKit.MessagesCollectionView) -> any MessageKit.MessageType {
    return messages[indexPath.section]
}

func numberOfSections(in messagesCollectionView: MessageKit.MessagesCollectionView) -> Int {
    return messages.count
}

}`

Xcode version 15.3
similator ios 17.2 15 Pro
messageKit 4.2.0

you forgot to refresh the collection view:
messagesCollectionView.reloadData()
