How can I push the list of messages all the way up when I don't have much message

Most pushed views allow swiping from the left side of the screen to pop them back to the previous view. This is especially helpful for chat views, where most of the screen is covered by the keyboard and the top-left back button is out of reach. It would be nice to have the option for chat views to be dismissed with this gesture.

I believe this is currently disabled due to the .navigationBarBackButtonHidden() modifier on the ChatNavigationModifier. A simple solution would be another field in that struct to allow the system back button instead of the themed one.

Thank you for your consideration!

1. the Reply btn on long press is hidden by the message that is long pressed when the message is >2 lines long
2. tapping the Reply btn doesnt actually change anything in the UI that I can tell.

Is there a way to turn off the long press?

I am interfacing with OpenAI's SSE format API, and I tried to update the content of corresponding messages. It can be confirmed that the message has been updated, but I did not see the update in the UI. Is there a problem with the way I call it?thx
My code

    private func updateBotMessage(_ text: String, messageId: String?) {
        DispatchQueue.main.async {
            if let currentId = self.currentBotMessageId,
               let index = self.messages.firstIndex(where: { $0.id == currentId }) {
                var updatedMessage = self.messages[index]
                updatedMessage.text += text
                self.messages[index] = updatedMessage
            } else {
                let newId = messageId ?? UUID().uuidString
                let newMessage = Message(
                    id: newId,
                    user: self.botUser,
                    status: .sent,
                    createdAt: Date(),
                    text: text
                )
                self.messages.append(newMessage)
                self.currentBotMessageId = newId
            }
            
            self.objectWillChange.send()

I am willing to implement delete the selected message.
Is there any way we can do in the current implementation.

Love this library 💯 would be really cool to see support for links, and for allowing to copy messages. Right now the long press just makes the "Reply" button show up.

Hi

I'm seeing occurrences of the NSInternalInconsistencyException crash, that seems to have been an issue for other users in the past based on closed issues:

Fatal Exception: NSInternalInconsistencyException Invalid batch updates detected: the number of sections and/or rows returned by the data source before and after performing the batch updates are inconsistent with the updates. Data source before updates = { 1 section with row counts: [3] } Data source after updates = { 1 section with row counts: [0] } Updates = [ Delete row (0 - 1), Delete row (0 - 0) ]

Crash coming from UIList.swift, line 104 as it attempts to performBatchUpdates.

I've not been able to replicate in testing as yet, but getting regular reports of the crash from our production release.

Any advice welcome... Thanks.

I'm using SPM inside a XCode project. I added this project and I keep getting this error

CrashReportError: App crashed because Chat.framework is missing

Not sure what is causing this, any particular idea?

I noticed that the "today" and "yesterday" indicators for a group of messages is displayed upside down.

Tested on iPhone15 and iOS 17 and 17.4

I'm seeking some advice regarding how I should go about adding message response buttons like we see in WhatsApp and other messaging platforms. They display convenient short answer options in a chat message as shown in the attachment. Any suggestions where I should start for implementing this capability? There can be limitations, such as a max of 3 buttons, and pressing the button only fills in the draft message and automatically sends the message. I would appreciate any thoughts about where to get started and which classes should be extended.

Thanks！

As per screenshot, integration with Xcode SPM not working. Other packages working as expected.

Hello
I am trying to use exyte chat for the first time but without success. In the most simple code:

@State var messages: [Message] = []

var body: some View {
ChatView(messages: messages) { draft in
//yourViewModel.send(draft: draft)
}
}

how can I initialize the messages array with a first sample message to be displayed when the screen first appears?
I am trying to use onAppear() to just append a simple and sample message but it is being hard to initialize it. Could you provide what to pass the the append call?

Thank you

Summary

Exyte Chat will throw an exemption after sending a message through the chat input text field.

Source of the Issue

The following exemption is thrown, and it is caused due to the TableView not having any cells to for which to render after NotificationCenter.default.post(name: .onScrollToBottom, object: nil) was called upon.

Attempted to scroll the table view to an out-of-bounds section (0) when there are only 0 sections

Notes

I noticed that Exyte Chat is using Notification Center to send .scrollToBottom event, and there is a timeout of 0.3.
I wonder if there is a race condition happening here in which the data source is not updated on time for that scroll event to call the table view.

Users can record for up to 60 seconds
Thanks!

is there support for dark mode without having to create a theme on my own. Maybe this should be an out to the box feature.

Love this repo. Impressive work.

How would i add dynamic font size for messages for people with bad eyes?

My users are mostly >50 years old. I see that font size of 15 is hardcoded on MessageView.swift line36. I love everything else about the MessageView, and definitely want to avoid implementing a custom messageBuilder if i can help it.

Is it possible to disable showing waitingForNetwork or at least provide a custom view when offline? Or disable NetworkMonitor at all? Thanks

Amazing Library, thanks you very much
would you guys make it compatible with iOS 15?
as the required version is too new to make the usage worldwide

Hi developer, Thank you for creating an excellent chat library In SwiftUI.

when I tried to delete the item at binding dataSource source, will crash immediately at performBatchUpdates in UIList, below is the log:
Thread 1: "Invalid batch updates detected: the number of sections and/or rows returned by the data source before and/or after performing the batch updates are inconsistent with the updates.\nData source before updates = { 1 section with row counts: [3] }\nData source after updates = { 1 section with row counts: [2] }\nUpdates = [\n\n]\nTable view: <UITableView: 0x125850a00;

I check the code, and the applyInserts function already exists to deal with delete cases.

Hi! First of all, thanks for open-sourcing this package!

I would like to customize the media types selectable in the media picker (only photos / only videos / both).
I am aware that ExyteMediaPicker allows defining a mediaSelectionType. However, if I understand correctly, ExyteChat only exposes the mediaSelectionLimit property of the underlying ExyteMediaPicker via an assetsPickerLimit modifier; the mediaSelectionType property is not exposed.

Is there a way for me to customize the media selection type directly from ExyteChat?
Thank you!

After adding new items into @Published var messages: [Message] = [] get a crash :(
When add only 1 item it works fine.

I think these should be pulling from one of the theme colors.

There are some other instances in the rest of that file.

I want to support custom message types. For example, I have documents that I want to send as a message when they are created. The message should contain information such as: title, blurb, documentId. How can I store this inside of a Message?

I would also want to provide custom styling, which I can assume can be done through messageBuilder. I am wondering how we can structure the Message so that we can switch on it inside the messageBuilder and display accordingly.

I want to keep all the displays of the standard messages the same other than my custom message type.

Any advice is greatly appreciated!

Баги:

• Анимация появления сообщения в чате какая-то дерганая, и все фотки мигают каждое новое сообщение почему-то - надо сделать плавную анимацию

Фичи (когда-то потом):

• Добавить плавающий хедер даты сверху чата (today, yesterday и все такое)
• Добавить контекстное меню:
  • "edit, delete" для своих сообщений
  • "retry, edit, delete" для своих сообщений которые зафейлились послаться
  • "reply" для чужих (тут надо будет еще в строку ввода добавить превью сообщения, на которое ты отвечаешь)
• Добавить возможность тегать по имени
• Разрешить отправлять локацию

I get the following warning in my console is there a fix for this

Using the example to build my own custom input view, I'm having a hard time understanding how I would dismiss the keyboard when the user taps on the chat view

I notice the internal implementation of the ChatView has

 @StateObject private var globalFocusState = GlobalFocusState()
.environmentObject(globalFocusState)

but that is not something I can access inside inputViewBuilder. I tried defining my own

@FocusState private var isChatFocus: Bool

but i don't have a handler to use to dismiss it when the user taps on the chat view. I tried onTapGesture on the chat view, but it doesn't fire.

ChatView(messages: viewModel.messages) { draft in
    viewModel.send(draft: draft)
} inputViewBuilder: { textBinding, attachments, state, style, actionClosure in
    Group {
        switch style {
        case .message: // input view on chat screen
            VStack {
                HStack {
                    Button("Send") { actionClosure(.send) }
                    Button("Attach") { actionClosure(.photo) }
                }
                TextField("Write your message", text: textBinding)
            }
        case .signature: // input view on photo selection screen
            VStack {
                HStack {
                    Button("Send") { actionClosure(.send) }
                }
                TextField("Compose a signature for photo", text: textBinding)
                    .background(Color.green)
            }
        }
    }
}```

Is there a way to only allow text as a message type? My app doesn't intend to send photos and I'd prefer not to fill out a NSPhotoLibraryUsageDescription since it really isn't needed.

As a suggestion - it may be helpful to first time users to outline what Privacy descriptions they may need so they can avoid the crash as well.

1. Run the app in the Simulator.
2. Tap the Camera button in text input view
3. CameraStubView is presented with Close button
4. Tap the Close button. Nothing happens.

Expected: CameraStubView should be closed when tapped on Close button

I need to manage this both on my end. Please provide the release time for the same.

I don't see a way to push a ChatView into a text-only or text-and-audio-only mode. Is this a reasonable feature request, or am I missing something?

After updating to 1.2.2 from 1.0.3, I'm getting Errors during compile in the latest Xcode 15.0.1 with iOS 17:

I tried resetting the SPM package cache and cleaning the project but the issue persists. Any ideas?

Does this natively support push notifications on new messages?

Hello,

I was looking at your library and I noticed you were using a UITableView in a UIList.swift instead of the List component.

Why did you do that ? What was the limitation ?

Thanks :)

I have been using the source code you created, and it's very well. Below, I have detailed what I've noticed while working with it.

PS: I translated this because I'm not proficient in English. If there are any parts you don't understand, please answer.

Working Environment:

• XCode: Version 14.3.1 (14E300c)
• Swift: Version 5
• iOS: 15.0 or higher

Feature Suggestions:

1. Add Menu on Message's Long Press Gesture:

• Copy message
• Edit message
• Delete message
• Forward
• Message's Long Press Gesture:

2. Add shadow to message Bubble

3. Detailed View of Image Messages:

• download image
• Copy image

4. Voice Message Recording:
- Provide voice spectrum instead of displaying "Recording..."
ex) https://volpato.dev/posts/speech-wave-visualization-in-swiftui/

5. When New Messages Arrive (with isScrolledToBottom = true):
- Display the number of new messages as a badge

6. Add Style to Buttons:
- Use .buttonStyle(.plain)

7. Add a Closure for Handling Message Display Animations

8. Feature to Change the Profile in the Message Window When the User Profile Changes

Things Suspected to be Bugs:

• Sometimes, the layout overlaps when displaying messages.
• The chat scroll animation operates abnormally, causing a shaking problem.
• The scroll animation behaves unpredictably when there are only a few messages (about 1-3).

Is it possible to add a 'user is typing' feature. Something like a message bubble with three dots and list of chat-users in the caption-label bellow the buble, indicating who is currently typing in the chat?

I am trying this repo with cocoapod for my project, however, there is no icon loaded in the chatview, I also double check the pod source and it seems the media resource was missing. Did we miss that on pod repo or I miss something? Thank you.

Can't tap on message avatar to display user profile

The code here uses NSAttributedString for rendering markdown.

Unfortunately I'm seeing this render incorrectly: \n in the input string does not result in a newline (or any whitespace at all) in the rendered output. ** and similar text instructions do work.

This seems like an old issue:

https://forums.developer.apple.com/forums/thread/682957

A potential workaround is to just dump the string straight into the Text.

If I get a chance this week I'll try to test this out myself, but I figured I'd file an issue first in case you beat me to it!

Now all chat configuration like showDateHeaders, messageUseMarkdown, avatarSize, etc, are simple variables and configured through methods from ChatView extension. It means, that it's possible to set them only locally, directly with a ChatView. I suggest to use EnvironmentValues instead that allows to setup all configs globally for the whole app and override them locally if needed.
Example:

extension EnvironmentValues {
   
   public struct Chat: Equatable {
     public var type: ChatType = .chat
     public var showDateHeaders: Bool = true
     public var avatarSize: CGFloat = 32
     public var messageUseMarkdown: Bool = false
     public var showMessageMenuOnLongPress: Bool = true
     public var tapAvatarClosure: TapAvatarClosure?
     public var mediaPickerSelectionParameters: MediaPickerParameters?
     public var orientationHandler: MediaPickerOrientationHandler = {_ in}
     public var chatTitle: String?
     public var showMessageTimeView = true
     public var messageFont = UIFontMetrics.default.scaledFont(for: UIFont.systemFont(ofSize: 15))
     public var availablelInput: AvailableInputType = .full
   }
   
   private enum ChatKey: EnvironmentKey {
     static let defaultValue = EnvironmentValues.Chat()
   }
   
   public var chat: Chat {
      get { self[ChatKey.self] }
      set { self[ChatKey.self] = newValue }
   }
}

extension View {

    public func chatView<T>(_ keyPath: WritableKeyPath<EnvironmentValues.Chat, T>, _ value: T) -> some View {
       environment(\.chat[keyPath: keyPath], value)
    }
    
    // convenience methods for each var if needed
}

Contextual closure type '(ModeSwitcher, AlbumSelectionView, Bool) -> some View' expects 3 arguments, but 2 were used in closure body
