Warning
We are no longer allowing new customers to onboard to Twilio Video. Effective December 5th, 2024, Twilio Video will End of Life (EOL) and will cease to function for all customers. Customers may transition to any video provider they choose, however, we are recommending customers migrate to the Zoom Video SDK and we have prepared a Migration Guide. Additional information on this EOL is available in our Help Center here.
NEW: Please check out the newly open-sourced video collaboration app built with iOS Video SDK.
NOTE: These sample applications use the Twilio Video 5.x APIs. For examples using previous releases please see the following repositories:

This repository contains example code written in both Objective-C and Swift.
If you haven't used Twilio before, welcome! You'll need to Sign up for a Twilio account first. It's free!
These Quickstarts expect that you have "Client-side Room Creation" enabled in your Twilio account. You can check this setting on the Default Room Settings page in the Twilio Console.
To get started with the Swift Quickstart application follow these steps:
- Open the
VideoQuickStarttarget from theVideoQuickStart.xcworkspacein Xcode
- Type in an identity and click on "Generate Access Token" from the Testing Tools page.
Note: If you enter the Room Name, then you can restrict this user's access to the specified Room only. Ideally, you want to implement and deploy an Access Token server to generate tokens. You can read more about setting up your own Access Token Server in this section. Read this tutorial to learn more about Access Tokens.
- Paste the token you generated in the earlier step in the
ViewController.swift.
- Run the Quickstart app on your iOS device or simulator.
-
As in Step 2, generate a new Token for another identity (such as "Bob"). Copy and paste the access token into
ViewController.swift(replacing the one you used earlier). Build and run the app on a second physical device if you have one, or the iPhone simulator. -
Once you have both apps running, enter an identical Room name (such as "my-cool-room") into both apps, and tap "Connect" to connect to a video Room (you'll be prompted for mic and camera access on the physical device). Once you've connected from both devices, you should see video!
To get started with the Objective-C Quickstart application follow these steps:
- Open the
ObjCVideoQuickstarttarget from theVideoQuickStart.xcworkspacein Xcode
- Type in an identity and click on "Generate Access Token" from the Testing Tools page.
Note: If you enter the Room Name, then you can restrict this user's access to the specified Room only. Ideally, you want to implement and deploy an Access Token server to generate tokens. You can read more about setting up your own Access Token Server in this section. Read this tutorial to learn more about Access Tokens.
- Paste the token you generated in the earlier step in the
ViewController.m.
- Run the Quickstart app on your iOS device or simulator.
-
As in Step 2, generate a new Token for another identity (such as "Bob"). Copy and paste the access token into
ViewController.m(replacing the one you used earlier). Build and run the app on a second physical device if you have one, or the iPhone simulator. -
Once you have both apps running, enter an identical Room name (such as "my-cool-room") into both apps, and tap "Connect" to connect to a video Room (you'll be prompted for mic and camera access on the physical device). Once you've connected from both devices, you should see video!
You can use the iOS Simulator that comes with Xcode to do your testing, but local video will not be shared since the Simulator cannot access a camera.
Note: If you have an iOS device, you can now run apps from Xcode on your device without a paid developer account.
You will also find additional examples that provide more advanced use cases of the Video SDK. The currently included examples are as follows:
- AudioDevice - Provide your own means to playback and record audio using a custom
AudioDeviceand CoreAudio. - AudioSink - Access raw audio samples and record them to disk using AVFoundation. Perform live voice recognition using Apple's Speech framework.
- ARKit - Captures augmented reality content with
ARKitand usesSceneKitto place objects in the virtual scene. The resulting rendering is previewed locally, and shared in aRoomvia a customVideoSourcesource. - AVPlayer - Shows how to use
AVPlayerto stream Audio & Video content while connected to aRoom. - CallKit - Shows how to use Twilio Video with the CallKit framework.
- DataTrack - Shows how to use the Data Track APIs for interactive drawing.
- Collaboration App - A collaboration app that demonstrates how to use the Room API for multiparty conferencing.
- ReplayKit - Shows how to use ReplayKit to share the screen, and microphone via
VideoSourceandAudioDevice. - Screen Capturer - Use a custom
VideoSourceto capture the contents of aWKWebView.
Using Twilio's Video client within your applications requires an access token. Access Tokens are short-lived credentials that are signed with a Twilio API Key Secret and contain grants which govern the actions the client holding the token is permitted to perform.
If you want to be a little closer to a real environment, you can download one of the video Quickstart server applications - for instance, Video Quickstart: PHP and either run it locally, or install it on a server. You can review a detailed tutorial.
You'll need to gather a couple of configuration options from the Twilio developer console before running it, so read the directions on the Quickstart. You'll copy the config.example.php file to a config.php file, and then add in these credentials:
| Credential | Description |
|---|---|
| Twilio Account SID | Your main Twilio account identifier - find it on your dashboard. |
| API Key | Used to authenticate - generate one here. |
| API Secret | Used to authenticate - just like the above, you'll get one here. |
Use whatever clever username you would like for the identity. If you enter the Room Name, then you can restrict this users access to the specified Room only. Read this tutorial for more information on Access Tokens.
When you generate an API key pair at the URLs above, your API Secret will only be shown once - make sure to save this in a secure location.
Because we suggest that you run your video chat application on actual iOS device so that you can use the camera on the device, you'll need to provide an externally accessible URL for the app (the iOS simulator will be fine with localhost). Ngrok creates a publicly accessible URL that you can use to send HTTP/HTTPS traffic to a server running on your localhost. Use HTTPS to make web connections that retrieve a Twilio access token.
When you get a URL from ngrok, go ahead and update ViewController.swift with the new URL. If you go down this path, be sure to follow the directions in the comments in the viewDidLoad() method at the top of the source file - you will need to uncomment one line, and comment out another. You will also need to update the code if your ngrok URL changes.
For this Quickstart, the Application transport security settings are set to allow arbitrary HTTP loads for testing your app. For production applications, you'll definitely want to retrieve access tokens over HTTPS/SSL.
