This app is a sample video conferencing app that uses the Twilio Programmable Video SDK. The open source app can be easily configured by developers to try out real-time video and audio features. Converting Objective-C code to Swift is in progress.

• Video conferencing with real-time video and audio
• Enable/disable camera
• Mute/unmute mic
• Switch between front and back camera
• Dominant speaker indicator
• Network quality indicator

The app requires a back-end to generate Twilio access tokens. Follow the instructions below to deploy a serverless back-end using Twilio Functions.

1. Install Twilio CLI.
2. Run twilio plugins:install @twilio-labs/plugin-rtc.
3. Run twilio rtc:apps:video:deploy --authentication passcode.
4. The passcode that is output will be used later to sign in to the app.

The passcode will expire after one week. To generate a new passcode:

1. Run twilio rtc:apps:video:delete.
2. Run twilio rtc:apps:video:deploy --authentication passcode.

1. Install CocoaPods.
2. Run pod install.

1. Open VideoApp.xcworkspace with Xcode.
2. In Xcode navigate to the Signing & Capabilities pane of the project editor for the Video-Community target.
3. Change Team to your team.
4. Change Bundle identifier to something unique.

1. In Xcode use the Scheme menu to select the Video-Community scheme.
2. In Xcode use the Scheme menu to select a destination. Cameras do not work in the simulator so select a device for best results.
3. Run ⌘R the app.

The Video-Twilio and Video-Internal schemes use authentication that is only available to Twilio employees in order to make internal testing easier.

For each device:

1. Run the app.
2. Enter any unique name in the Your name field.
3. Enter the passcode from Deploy Twilio Access Token Server in the Passcode field.
4. Tap Sign in.
5. Enter a room name.
6. Tap Join.

The passcode will expire after one week. Follow the steps below to sign in with a new passcode.

1. Generate a new passcode.
2. In the app tap Settings > Sign Out.
3. Repeat the steps above.

For unit tests use:

• Video-Twilio scheme.
• Video-TwilioTests target.
• Quick and Nimble to write unit tests.
• Swift Mock Generator to create mocks.

UI tests require credentials that are only available to Twilio employees.

1. Running tests ⌘U will crash if the app was run ⌘R on the device previously. See issue #12 for a workaround and more details.

• Twilio Video Android App
• Twilio Video React App
• Twilio CLI RTC Plugin

Twilio employees should follow these instructions for internal testing.
