### Creating the App Structure

Our app will have two main screens:
1. A Join Stream View for entering or creating streams
2. A Live Stream View for the actual streaming interface

Here's a simplified example of the Join Stream View in SwiftUI:

```swift
struct JoinStreamView: View {
    @State var streamId: String = ""
    @State var name: String = ""

    var body: some View {
        NavigationView {
            ZStack {
                // Background styling
                
                VStack {
                    // App title headers
                    
                    // Create Stream Button
                    NavigationLink(
                        destination: LiveStreamView(
                            userName: name.isEmpty ? "Guest" : name, 
                            mode: .SEND_AND_RECV
                        )
                    ) {
                        ActionButton(title: "Create Live Stream", icon: "plus.circle.fill")
                    }
                    
                    // Stream ID input field
                    
                    // Join options
                    HStack {
                        // Join as Host button (SEND_AND_RECV mode)
                        // Join as Audience button (RECV_ONLY mode)
                    }
                }
            }
        }
    }
}
```

### Initializing and Joining the Live Stream

Create a view controller to handle the streaming functionality:

```swift
class LiveStreamViewController: ObservableObject {
    var token = "YOUR_TOKEN"
    @Published var meeting: Meeting? = nil
    @Published var participants: [Participant] = []
    @Published var streamID: String = ""

    // Initialize a stream with specific mode (host or audience)
    func initializeStream(streamId: String, userName: String, mode: Mode) {
        // Initialize the meeting with VideoSDK
        meeting = VideoSDK.initMeeting(
            meetingId: streamId,
            participantName: userName,
            micEnabled: true,
            webcamEnabled: true,
            mode: mode
        )
        
        // Join the stream and add event listeners
        meeting?.join()
        meeting?.addEventListener(self)
    }
    
    // Create a new stream
    func joinRoom(userName: String, mode: Mode) {
        // API call to create new room
    }
    
    // Join existing stream
    func joinStream(streamId: String, userName: String, mode: Mode) {
        // Join with provided stream ID
    }
}

// Event listeners for meeting events
extension LiveStreamViewController: MeetingEventListener {
    func onMeetingJoined() {
        // Handle local participant joining
    }
    
    func onParticipantJoined(_ participant: Participant) {
        // Add new participant to the list
    }
    
    // Other event handling methods
}

// Event listeners for participant events
extension LiveStreamViewController: ParticipantEventListener {
    func onStreamEnabled(_ stream: MediaStream, forParticipant participant: Participant) {
        // Handle media stream being enabled
    }
    
    func onStreamDisabled(_ stream: MediaStream, forParticipant participant: Participant) {
        // Handle media stream being disabled
    }
}
```

### Creating the Live Stream View

The main streaming interface includes participant videos and control buttons:

```swift
struct LiveStreamView: View {
    @ObservedObject var liveStreamViewController = LiveStreamViewController()
    @State private var currentMode: Mode
    @State var isUnMute: Bool = true
    @State var camEnabled: Bool = true

    // Check if the user is in audience mode
    private var isAudienceMode: Bool {
        // Logic to determine if user is in audience mode
    }

    var body: some View {
        VStack {
            if liveStreamViewController.participants.isEmpty {
                Text("Stream Initializing")
            } else {
                VStack {
                    // Stream ID information
                    
                    // Participant videos
                    List {
                        // Display participants who are broadcasting
                    }
                    
                    // Media controls for hosts
                    if !isAudienceMode {
                        HStack {
                            // Mic toggle button
                            // Camera toggle button
                        }
                    }
                    
                    // General controls
                    HStack {
                        // Leave stream button
                        
                        // Mode switching button
                        Button {
                            let newMode: Mode = isAudienceMode ? .SEND_AND_RECV : .RECV_ONLY
                            liveStreamViewController.meeting?.changeMode(newMode)
                            currentMode = newMode
                        } label: {
                            Text(isAudienceMode ? "Switch to Host" : "Switch to Audience")
                        }
                    }
                }
            }
        }
        .onAppear {
            // Initialize VideoSDK and join stream
        }
    }
}
```

## Adding Interactive Features with VideoSDK

### Implementing Live Activities

For iOS 16+, you can add Live Activities to show stream status on the Lock Screen and Dynamic Island:

```swift
import ActivityKit
import WidgetKit

// Define the Live Activity attributes
struct StreamActivityAttributes: ActivityAttributes {
    public struct ContentState: Codable, Hashable {
        var viewerCount: Int
        var isLive: Bool
        var elapsedTime: TimeInterval
        var recentMessage: String?
    }
    
    var streamTitle: String
    var channelName: String
    var broadcasterName: String
}

// Add Live Activity methods to your controller
extension LiveStreamViewController {
    // Start Live Activity
    func startLiveActivity() {
        // Initialize activity with streaming metadata
    }
    
    // Update Live Activity with new information
    func updateLiveActivity(viewerCount: Int, recentMessage: String? = nil) {
        // Update the activity with new data
    }
    
    // End Live Activity when stream ends
    func endLiveActivity() {
        // Finalize the activity
    }
}
```

## Optimizing Performance and Scalability

### Handling Network Conditions

With VideoSDK, you can optimize streaming quality based on network conditions:

```swift
extension LiveStreamViewController {
    func optimizeForNetworkConditions() {
        // Set up network quality monitoring
        
        // Set initial stream quality
        meeting?.localParticipant.setQuality(.high)
    }
    
    @objc func handleNetworkQualityChange(_ notification: Notification) {
        if let quality = notification.userInfo?["quality"] as? NetworkQuality {
            // Adjust video quality based on network conditions
            switch quality {
            case .poor:
                meeting?.localParticipant.setQuality(.low)
                showNetworkWarningUI()
            case .good:
                meeting?.localParticipant.setQuality(.medium)
                hideNetworkWarningUI()
            case .excellent:
                meeting?.localParticipant.setQuality(.high)
                hideNetworkWarningUI()
            }
        }
    }
}
```

## Key Takeaways

When implementing interactive live streaming in iOS apps with VideoSDK:

1. **Consider participant modes**: Use the appropriate mode (SEND_AND_RECV for hosts, RECV_ONLY for audience) to optimize performance and bandwidth.

2. **Provide mode switching**: Allow users to transition between host and audience roles dynamically.

3. **Optimize network handling**: Implement network quality detection and adjust streaming quality accordingly.

4. **Enhance with Live Activities**: For iOS 16+, add Lock Screen and Dynamic Island integration for better user engagement.

5. **Manage permissions properly**: Ensure camera and microphone permissions are properly requested and handled.

6. **Test on real devices**: Simulator testing is insufficient for evaluating performance and user experience.

## Conclusion

How to Implement Interactive Live Streaming in iOS Apps: A Swift/Objective-C SDK Guide

Learn how to build an interactive live streaming application using React and VideoSDK. This comprehensive guide covers component structure, implementing host and viewer screens, and adding interactive features like chat, polls, and reactions.

Interactive live streaming has revolutionized digital engagement, with video consumption rising 47% in the past year. While traditional streaming offers one-way communication, interactive streaming creates dynamic, two-way experiences that boost audience retention and provide new monetization opportunities.

However, building robust interactive live streaming applications requires expertise in video processing, real-time communication, and user experience design. React's component-based architecture, efficient rendering, and rich ecosystem make it an ideal framework for tackling these challenges.

This guide will walk you through creating a complete interactive live streaming application with React and VideoSDK.

## What Makes React Ideal for Live Streaming Applications?

React offers several advantages for building live streaming applications:

- **Component-Based Structure**: Create reusable UI components for video players, chat interfaces, and control panels
- **Virtual DOM**: Ensure smooth performance with real-time updates
- **Rich Ecosystem**: Access libraries specifically designed for media streaming
- **Declarative Approach**: Simplify management of complex state changes

The following diagram illustrates the architecture of a React-based interactive live streaming application, showing how hosts and viewers connect through VideoSDK:

![React Interactive Live Streaming Architecture](https://strapi.videosdk.live/uploads/Group_11809_min_f2e3891294.png)

## Planning Your Interactive Live Streaming Application

Before writing code, identify your application's key elements:

### User Roles

Understanding the different user roles in your live streaming application is crucial for designing the right experience for each participant type:

![User Roles in Interactive Live Streaming](https://strapi.videosdk.live/uploads/Group_11811_min_962cd69d61.png)

As shown in the diagram above, our application will support three primary roles:

- **Speakers/Hosts**: Users who broadcast audio/video and control the stream (SEND_AND_RECV mode)
- **Viewers**: Users who watch the stream and participate through interactive features (RECV_ONLY mode)
- **Moderators** (optional): Users who can manage chat and interactive elements

### Key Features
- Real-time video and audio streaming
- Chat functionality
- Interactive elements (polls, Q&A, reactions)
- Media controls (camera/microphone toggle)
- User authentication (optional)

## Setting Up Your Development Environment

Let's start by creating a new React application and installing the necessary dependencies:

```bash
# Create a new React application
npx create-react-app videosdk-live-streaming-app

# Install required packages
npm install @videosdk.live/react-sdk react-player hls.js
```

## Project Structure

For a clean, maintainable codebase, organize your project with a logical component hierarchy:

![React Component Hierarchy for Live Streaming](https://strapi.videosdk.live/uploads/Group_11810_min_6b57f231d3.png)

As shown in the hierarchy diagram, our project will be structured as follows:

```
src/
├── screens/
│   ├── WelcomeScreen.js
│   ├── SpeakerScreen/
│   │   ├── MediaControls.js
│   │   ├── ParticipantsGrid.js
│   │   └── SpeakerScreen.js
│   └── ViewerScreen.js
├── components/
│   ├── Chat.js
│   ├── Polls.js
│   └── Reactions.js
├── api.js
└── App.js
```

## Implementing Core Functionality

### API Configuration

First, set up the VideoSDK authentication and room creation:

```jsx
// api.js
export const authToken = "YOUR_VIDEOSDK_TOKEN";

export const createNewRoom = async () => {
  const res = await fetch(`https://api.videosdk.live/v2/rooms`, {
    method: "POST",
    headers: {
      authorization: authToken,
      "Content-Type": "application/json",
    },
  });

  const { roomId } = await res.json();
  return roomId;
};
```

### Welcome Screen

This screen lets users create or join streams:

```jsx
// WelcomeScreen.js
import React, { useState } from "react";
import { createNewRoom } from "../api";

function WelcomeScreen({ setAppData }) {
  const [meetingId, setMeetingId] = useState("");

  const createStream = async () => {
    const roomId = await createNewRoom();
    setAppData({ mode: "CONFERENCE", meetingId: roomId });
  };
  
  return (
    <div className="welcome-screen">
      <h1>Interactive Live Streaming</h1>
      
      <button onClick={createStream}>
        Create New Stream
      </button>
      
      <div className="divider">OR</div>
      
      <input
        placeholder="Enter Stream ID"
        value={meetingId}
        onChange={(e) => setMeetingId(e.target.value)}
      />
      
      <div className="buttons">
        <button onClick={() => setAppData({ mode: "CONFERENCE", meetingId })}>
          Join as Host
        </button>
        
        <button onClick={() => setAppData({ mode: "VIEWER", meetingId })}>
          Join as Viewer
        </button>
      </div>
    </div>
  );
}
```

### Main App Component

The App component manages application state and renders the appropriate screen:

```jsx
// App.js
import React, { useState } from "react";
import SpeakerScreen from "./screens/SpeakerScreen/SpeakerScreen";
import ViewerScreen from "./screens/ViewerScreen";
import WelcomeScreen from "./screens/WelcomeScreen";

function App() {
  const [appData, setAppData] = useState({ meetingId: null, mode: null });

  // Render different screens based on app state
  if (!appData.meetingId) {
    return <WelcomeScreen setAppData={setAppData} />;
  }
  
  return appData.mode === "CONFERENCE" 
    ? <SpeakerScreen meetingId={appData.meetingId} /> 
    : <ViewerScreen meetingId={appData.meetingId} />;
}
```

### Speaker Screen Implementation

The speaker screen consists of:
1. A container to initialize VideoSDK
2. Media controls for audio, video, and streaming
3. A grid to display participants

```jsx
// SpeakerScreen.js
import { MeetingProvider } from "@videosdk.live/react-sdk";
import React from "react";
import MediaControls from "./MediaControls";
import ParticipantsGrid from "./ParticipantsGrid";
import { authToken } from "../../api";

function SpeakerScreen({ meetingId }) {
  return (
    <MeetingProvider
      token={authToken}
      config={{
        meetingId,
        name: "Host",
        micEnabled: true,
        webcamEnabled: true,
      }}
      joinWithoutUserInteraction
    >
      <div className="speaker-screen">
        <MediaControls />
        <ParticipantsGrid />
      </div>
    </MeetingProvider>
  );
}
```

The media controls component manages audio, video, and HLS streaming:

```jsx
// MediaControls.js
import { useMeeting, Constants } from "@videosdk.live/react-sdk";
import React, { useMemo } from "react";

function MediaControls() {
  const { toggleMic, toggleWebcam, startHls, stopHls, hlsState } = useMeeting();

  // Determine HLS state
  const { isHlsStarted, isHlsStopped } = useMemo(() => ({
    isHlsStarted: hlsState === Constants.hlsEvents.HLS_STARTED,
    isHlsStopped: hlsState === Constants.hlsEvents.HLS_STOPPED,
  }), [hlsState]);

  // Toggle HLS streaming
  const toggleHls = () => {
    if (isHlsStarted) {
      stopHls();
    } else if (isHlsStopped) {
      startHls({ quality: "high" });
    }
  };

  return (
    <div className="controls">
      <div className="stream-info">
        <p>Stream Status: {hlsState}</p>
      </div>
      
      <div className="buttons">
        <button onClick={toggleMic}>Toggle Mic</button>
        <button onClick={toggleWebcam}>Toggle Camera</button>
        <button onClick={toggleHls}>
          {isHlsStarted ? "Stop Stream" : "Start Stream"}
        </button>
      </div>
    </div>
  );
}
```

The participants grid displays all connected users:

```jsx
// ParticipantsGrid.js
import { useMeeting } from "@videosdk.live/react-sdk";
import React, { useMemo } from "react";
import Participant from "./Participant";

function ParticipantsGrid() {
  const { participants } = useMeeting();
  
  // Get list of participant IDs
  const participantIds = useMemo(() => 
    [...participants.keys()], [participants]
  );

  return (
    <div className="participants-grid">
      {participantIds.map(participantId => (
        <Participant 
          key={participantId} 
          participantId={participantId} 
        />
      ))}
    </div>
  );
}
```

### Viewer Screen Implementation

The viewer screen shows the HLS stream once the speaker starts broadcasting:

```jsx
// ViewerScreen.js
import { MeetingProvider, MeetingConsumer, Constants } from "@videosdk.live/react-sdk";
import React, { useEffect, useRef } from "react";
import Hls from "hls.js";
import { authToken } from "../api";

function HLSPlayer({ playbackUrl }) {
  const videoRef = useRef(null);
  
  useEffect(() => {
    if (playbackUrl && Hls.isSupported()) {
      const hls = new Hls({
        capLevelToPlayerSize: true,
        maxLoadingDelay: 4,
        minAutoBitrate: 0,
      });
      
      hls.loadSource(playbackUrl);
      hls.attachMedia(videoRef.current);
    }
  }, [playbackUrl]);

  return (
    <video 
      ref={videoRef} 
      autoPlay 
      controls
      className="hls-player"
    />
  );
}

function ViewerScreen({ meetingId }) {
  return (
    <MeetingProvider
      token={authToken}
      config={{ 
        meetingId, 
        name: "Viewer",
        mode: "VIEWER" 
      }}
      joinWithoutUserInteraction
    >
      <MeetingConsumer>
        {({ hlsState, hlsUrls }) =>
          hlsState === Constants.hlsEvents.HLS_PLAYABLE ? (
            <HLSPlayer playbackUrl={hlsUrls.playbackHlsUrl} />
          ) : (
            <div className="waiting">
              <p>Waiting for the host to start streaming...</p>
            </div>
          )
        }
      </MeetingConsumer>
    </MeetingProvider>
  );
}
```

## Adding Interactive Features

Now, let's add key interactive features to enhance engagement.

### Chat Component

Implement real-time chat using VideoSDK's PubSub:

```jsx
// Chat.js
import React, { useState, useEffect } from "react";
import { usePubSub } from "@videosdk.live/react-sdk";

function Chat() {
  const [messages, setMessages] = useState([]);
  const [messageText, setMessageText] = useState("");
  const { publish, messages: pubSubMessages } = usePubSub("CHAT");

  useEffect(() => {
    if (pubSubMessages) {
      // Format and set messages
      const formattedMessages = pubSubMessages.map(msg => ({
        text: msg.message,
        sender: msg.senderName,
        timestamp: msg.timestamp
      }));
      
      setMessages(formattedMessages);
    }
  }, [pubSubMessages]);

  const sendMessage = () => {
    if (messageText.trim()) {
      publish(messageText, { persist: true });
      setMessageText("");
    }
  };

  return (
    <div className="chat">
      <div className="messages">
        {messages.map((msg, index) => (
          <div key={index} className="message">
            <span className="sender">{msg.sender}</span>
            <p>{msg.text}</p>
          </div>
        ))}
      </div>
      
      <div className="message-input">
        <input
          value={messageText}
          onChange={(e) => setMessageText(e.target.value)}
          placeholder="Type your message..."
          onKeyPress={(e) => e.key === "Enter" && sendMessage()}
        />
        <button onClick={sendMessage}>Send</button>
      </div>
    </div>
  );
}
```

### Polls Component

Create interactive polls for audience engagement:

```jsx
// Polls.js
import React, { useState, useEffect } from "react";
import { usePubSub } from "@videosdk.live/react-sdk";

function Polls() {
  const [polls, setPolls] = useState([]);
  const [newPoll, setNewPoll] = useState({ question: "", options: ["", ""] });
  const { publish, messages } = usePubSub("POLLS");

  useEffect(() => {
    if (messages) {
      const pollsData = messages.map(msg => JSON.parse(msg.message));
      setPolls(pollsData);
    }
  }, [messages]);

  const createPoll = () => {
    // Create and publish poll
    const poll = {
      id: Date.now(),
      question: newPoll.question,
      options: newPoll.options.map(text => ({ text, votes: 0 })),
    };
    
    publish(JSON.stringify(poll), { persist: true });
    
    // Reset form
    setNewPoll({ question: "", options: ["", ""] });
  };

  const vote = (pollId, optionIndex) => {
    // Handle voting logic
    const updatedPolls = polls.map(poll => {
      if (poll.id === pollId) {
        const newOptions = [...poll.options];
        newOptions[optionIndex].votes += 1;
        return { ...poll, options: newOptions };
      }
      return poll;
    });
    
    // Find and publish updated poll
    const updatedPoll = updatedPolls.find(p => p.id === pollId);
    publish(JSON.stringify(updatedPoll), { persist: true });
  };

  return (
    <div className="polls">
      {/* Poll creation form */}
      <div className="create-poll">
        <input
          placeholder="Enter your question"
          value={newPoll.question}
          onChange={(e) => setNewPoll({ ...newPoll, question: e.target.value })}
        />
        
        {/* Option inputs */}
        {newPoll.options.map((option, index) => (
          <input
            key={index}
            placeholder={`Option ${index + 1}`}
            value={option}
            onChange={(e) => {
              const newOptions = [...newPoll.options];
              newOptions[index] = e.target.value;
              setNewPoll({ ...newPoll, options: newOptions });
            }}
          />
        ))}
        
        <button onClick={() => setNewPoll({
          ...newPoll,
          options: [...newPoll.options, ""]
        })}>
          Add Option
        </button>
        
        <button onClick={createPoll}>Create Poll</button>
      </div>
      
      {/* Polls list */}
      <div className="polls-list">
        {polls.map(poll => (
          <div key={poll.id} className="poll">
            <h4>{poll.question}</h4>
            
            {poll.options.map((option, index) => (
              <div key={index} className="option">
                <span>{option.text} ({option.votes} votes)</span>
                <button onClick={() => vote(poll.id, index)}>
                  Vote
                </button>
              </div>
            ))}
          </div>
        ))}
      </div>
    </div>
  );
}
```

### Reactions Component

Add emoji reactions for simple audience participation:

```jsx
// Reactions.js
import React, { useState, useEffect } from "react";
import { usePubSub } from "@videosdk.live/react-sdk";

const REACTIONS = ["👍", "❤️", "😂", "👏", "🎉"];

function Reactions() {
  const { publish, messages } = usePubSub("REACTIONS");
  const [activeReactions, setActiveReactions] = useState([]);

  // Handle sending reactions

### Testing Your Setup (Audio and Video Quality)
