Publish WebRTC stream in iOS

Step 3: Publish a WebRTC Live Stream in iOS

  • Open "Main.storyboard" and go to View > Show Library. Search for "UIView" in the library search box.

  • Drag the "View" onto the Main.storyboard and adjust its size as needed.

  • Connect the UIView to the ViewController using the following steps:

  1. Open two editors: one for Main.storyboard and another for ViewController.swift.
  2. Right-click on the UIView in Main.storyboard, drag it to the next editor, and release the right-click. Name your Outlet.
  • Then it should look like below.

  • Add Privacy descriptions to Info.plist:

  1. Right-click on Info.plist and select "Add Row."
  2. Add descriptions for Camera Usage and Microphone Usage.
  • Finally, Info.plist looks like below

  • Edit the ViewController.swift file. Here we just initialize the AntMediaClient and set the WebSocket URL as Ant Media’s Test URL(or just use your own Ant Media Server URL) and call the publish with streamId parameter. streamId is unique and it’s recommend to use your random stream id if you use Ant Media’s Test URL.

import UIKit
import WebRTCiOSSDK

class ViewController: UIViewController {

@IBOutlet weak var videoView: UIView!
var client:AntMediaClient = AntMediaClient.init();

override func viewDidLoad() {
client.setLocalView(container: videoView);
client.setWebSocketServerUrl(url: "wss://");
client.publish(streamId: "stream123456")

  • Run your application on your device and grant Camera and Microphone Usage permissions.

  • Congratulations! You are now publishing your live stream.

  • To play the stream, visit Ant Media's Test WebRTC Player, enter the streamId "stream123456" in the box, and click "Start Playing."
