Disconnecting From the Session
Press the Leave button and you’ll notice the app doesn’t call sessionDidDisconnect(). That’s because the session is still connected. When leaving a session, it’s important that you make sure to disconnect from it.
In StreamingViewController.swift, replace the body of leave() with the following:
var error: OTError?
session?.disconnect(&error)
if let error = error {
print("An error occurred disconnecting from the session", error)
} else {
navigationController?.popViewController(animated: true)
}
This disconnects you from the session, which automatically unpublishes your stream when you tap the Leave button. It then pops the current view controller from the navigation stack, if no synchronous error occurred when disconnecting.
Inside session(_:streamDestroyed:), add the following code at the bottom:
subscriberView?.removeFromSuperview()
This removes the subscriber’s view from the screen when they stop publishing their stream in the session.
Now, build and run and double-check that leaving and entering the lounge works as you expect.
And, just like that, you now have a fully functioning app ready to install onto real devices so you can have a virtual tea party with your friend! :]
Where to Go From Here?

In this tutorial, you learned a lot about how to create a livestreaming event. You got to know important terms like WebRTC, HLS and RTMP, you set up your Vonage Video API account and you built a two-way live video streaming app using the Vonage Video API.
However, this project just scraped the surface of the Vonage Video API’s capabilities. There’s still plenty to learn, including:
-
Archiving: Record, save and retrieve sessions.
-
Signaling: Send text and data between clients connected to the session.
-
Server integration: Handle interactions between the client and server SDKs to automatically distribute tokens, session IDs and more.
-
Broadcasts: Set up HLS, RTMP and WebRTC broadcasts simultaneously.
-
SIP Interconnect: Add audio from a VoIP call to a session.
-
Voice-only: Set up voice-only sessions.
If you want to learn more about the capabilities of the Vonage Video API, check out their developer guides.
Also make sure you read about iOS video streaming using Apple’s frameworks in our Video Streaming Tutorial for iOS.
