Message Kinds

public enum ChatMessageKind {
    
    /// A text message,
    /// supports emoji 👍🏻 (auto scales if text is all about emojis)
    case text(String)
    
    /// An image message, from local(UIImage) or remote(URL).
    case image(ImageLoadingKind)
    
    /// A location message, pins given location & presents on MapKit.
    case location(LocationItem)
    
    /// A contact message, generally for sharing purpose.
    case contact(ContactItem)
    
    /// Multiple options, disables itself after selection.
    case quickReply([QuickReplyItem])
    
    /// `CarouselItem`s that contains title, subtitle, image & button in a scrollable view
    case carousel([CarouselItem])
    
    /// A video message, opens the given URL.
    case video(VideoItem)
}

Usage

• ChatView

Here below is minimum code required to get started (see up & running)
For detail, visit example project here

import SwiftyChat
import SwiftyChatMock

@State private var scrollToBottom = false
@State private var messages: [MockMessages.ChatMessageItem] = [] // for quick test assign MockMessages.generatedMessages()

// ChatMessageItem & ChatUserItem is a sample objects/structs 
// that conforms `ChatMessage` & `ChatUser` protocols.
ChatView<MockMessages.ChatMessageItem, MockMessages.ChatUserItem>(
    messages: $messages,
    scrollToBottom: $scrollToBottom
) {
    // InputView here, continue reading..
}
// ▼ Required
.environmentObject(
    // All parameters initialized by default, 
    // change as you want.
    ChatMessageCellStyle()
)
.onReceive(
    messages.debounce(for: .milliseconds(650), scheduler: RunLoop.main),
    perform: { _ in
        scrollToBottom = true
    }
)
// ...

• InputView

You can investigate existing BasicInputView in project.
You can use it if it suits your need, or create a new one.
Recommended way is just clone this BasicInputView and modify (ex. add camera icon etc.)

// InputBarView variables
@State private var message = ""

var inputBarView: some View {
    BasicInputView(
        message: $message, // Typed text.
        placeholder: "Type something",
        onCommit: { messageKind in
            self.messages.append(
                .init(user: MockMessages.sender, messageKind: messageKind, isSender: true)
            )
        }
    )
    .background(Color.primary.colorInvert())
    // ▼ An extension that wraps view inside AnyView
    .embedInAnyView()
}

// Pass in ChatView
ChatView(messages: $messages) {
    inputBarView 
}
...
...

Style and Customization

public class ChatMessageCellStyle: ObservableObject {
    
    let incomingTextStyle: TextCellStyle
    let outgoingTextStyle: TextCellStyle
    
    let incomingCellEdgeInsets: EdgeInsets
    let outgoingCellEdgeInsets: EdgeInsets
    
    let contactCellStyle: ContactCellStyle
    
    let imageCellStyle: ImageCellStyle
    
    let quickReplyCellStyle: QuickReplyCellStyle
    
    let carouselCellStyle: CarouselCellStyle
    
    let locationCellStyle: LocationCellStyle
    
    let incomingAvatarStyle: AvatarStyle
    let outgoingAvatarStyle: AvatarStyle
    
}

You must initiate this class to build a proper style & inject it as environmentObject,
All styles has default initializer;

You can also use your own custom message cell, see CustomMessage.md for details.
