💬 Chatwoot Agent iOS SDK (UIKit)

A lightweight iOS SDK built with Swift and UIKit to embed a Chatwoot-powered chat interface in any iOS app.

🎯 Objective

• Enable any iOS app to launch a full-featured Chatwoot chat screen
• Use UIKit for broad iOS compatibility (iOS 12+)

🧱 Supported Platforms

• ✅ Swift 5.7+
• ✅ UIKit Framework
• ✅ iOS 12+ (Broad device compatibility)
• ✅ SwiftUI Compatible (via UIViewControllerRepresentable)

📦 Installation

Via Swift Package Manager (Remote)

In Package.swift:

.package(url: "https://github.com/chatwoot/ios-agent-sdk", from: "1.0.0")

Via Xcode (Local Package)

1. Open your Xcode project
2. Add Package Dependency:
   • Go to File → Add Package Dependencies...
   • Click Add Local.. (bottom left)
   • Navigate to your local ios-sdk folder
   • Select the folder and click Add Package
3. Configure Package: Select your target(s) and click Add Package

Import in your app:

import ChatwootSDK

📸 Camera and Photo Library Permissions (Required)

To enable photo capture or image upload features in the chat interface, you must add the following keys to your app’s Info.plist:

<key>NSCameraUsageDescription</key>
<string>This app uses the camera to let you capture and upload photos in chat.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app needs access to your photo library to let you pick images for chat.</string>

How to add in Xcode:

1. Open your project in Xcode.
2. Locate your app target’s Info.plist file in the Project Navigator.
3. Right-click and select “Add Row”, then add each key above with a clear description string.
   • NSCameraUsageDescription: Explains why the app uses the camera (e.g., photo capture for chat).
   • NSPhotoLibraryUsageDescription: Explains why the app needs photo library access (e.g., image upload for chat).

🛠️ Example Usage

Step 1: Set up the SDK

// Create mandatory header icons as UIImage objects from SVG files using SVGKit
let backArrowIcon = createUIImageFromSVG(named: "back_arrow.svg")
let connectedIcon = createUIImageFromSVG(named: "connected_icon.svg")
let disconnectedIcon = createUIImageFromSVG(named: "disconnected_icon.svg")

ChatwootSDK.setup(ChatwootConfiguration(
    accountId: 1,
    apiHost: "https://your-chatwoot.com",
    accessToken: "YOUR_ACCESS_TOKEN",
    pubsubToken: "YOUR_PUBSUB_TOKEN",
    websocketUrl: "wss://your-chatwoot.com",
    inboxName: "Support",          // Display name for the inbox
    inboxNameFontSize: 20,       // Optional: font size for inbox name (default: 18)
    backArrowIcon: backArrowIcon,  // Required: UIImage object
    connectedIcon: connectedIcon,  // Required: UIImage object
    disconnectedIcon: disconnectedIcon, // Required: UIImage object
    disableEditor: false,        // Optional: disable message editor
    editorDisableUpload: false   // Optional: disable file uploads
))

Step 2: Show the Chat Interface (Recommended: Always Present from UIKit)

Present Modally from UIKit (Recommended for Theming):

// UIKit Example
ChatwootSDK.presentChat(from: self, conversationId: 123)

SwiftUI Example (Call UIKit Presentation):

import SwiftUI
import ChatwootSDK

struct ContentView: View {
    @State private var conversationId: String = "14635"
    
    var body: some View {
        Button("Open Chat") {
            presentChatFromRoot()
        }
    }
    
    private func presentChatFromRoot() {
        guard let conversationIdInt = Int(conversationId) else { return }
        if let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
           let rootVC = windowScene.windows.first?.rootViewController {
            ChatwootSDK.presentChat(from: rootVC, conversationId: conversationIdInt)
        }
    }
}

• This approach ensures correct status bar theming and avoids SwiftUI modal limitations.
• Do not use .fullScreenCover or UIViewControllerRepresentable for presenting the chat if you want full theming support.

The conversationId is required to load the chat UI. Make sure you have a valid conversation ID before calling loadChatUI.

🎨 Theme Customization

// Set colors using UIColor or hex string
ChatwootSDK.setThemeColor(.systemBlue)
ChatwootSDK.setThemeColor("#1f93ff")
ChatwootSDK.setTextColor(.white)
