Video iOS Platform Overview


(warning)

Warning

This page is for reference only. We are no longer onboarding new customers to Programmable Video. Existing customers can continue to use the product until December 5, 2024(link takes you to an external page).
We recommend migrating your application to the API provided by our preferred video partner, Zoom. We've prepared this migration guide(link takes you to an external page) to assist you in minimizing any service disruption.

Twilio's Programmable Video iOS SDK lets you add real time voice and video to your native iOS applications.


Prerequisites

prerequisites page anchor
  • Xcode 13.0+
  • Swift projects must use Swift 5.0 or higher
  • Support for iOS 12.2+

Programmable Video Live Demo

programmable-video-live-demo page anchor

Launch our Twilio Programmable Video live demo(link takes you to an external page) in less than 5 minutes. A high-quality, full-featured and open-source video collaboration application.


To get started with Twilio Video, you should download and run a QuickStart Application(link takes you to an external page).

Using a Simulator

using-a-simulator page anchor

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. If you have an iOS device, you can now run apps from Xcode on your device without a paid developer account.

The QuickStart repository(link takes you to an external page) contains additional examples. These examples demonstrate the usage of new features and also let you build more complex applications.

To add Video to your app, follow the Getting Started Guide


The Twilio Video iOS SDK dynamic framework can be installed using Swift Package Manager, CocoaPods or manually, as you prefer.

You can add Programmable Video for iOS by adding the https://github.com/twilio/twilio-video-ios repository as a Swift Package.

In your Build Settings, you will also need to modify Other Linker Flags to include -ObjC.

There is a known issue(link takes you to an external page) with consuming binary frameworks distributed via Swift Package Manager. The current workaround to this issue is to add a Run Script Phase to the Build Phases of your Xcode project. This Run Script Phase should come after the Embed Frameworks build phase. This new Run Script Phase should contain the following code:


_10
find "${CODESIGNING_FOLDER_PATH}" -name '*.framework' -print0 | while read -d $'\0' framework
_10
do
_10
codesign --force --deep --sign "${EXPANDED_CODE_SIGN_IDENTITY}" --preserve-metadata=identifier,entitlements --timestamp=none "${framework}"
_10
done


_10
source 'https://github.com/CocoaPods/Specs'
_10
_10
platform :ios, '12.2'
_10
_10
target 'TARGET_NAME' do
_10
pod 'TwilioVideo', '~> 5'
_10
end

Then run pod install to install the dependencies to your project.

TwilioVideo.xcframework is distributed as a dynamic iOS framework that you can drag and drop into your existing projects.

View all Video iOS Releases here(link takes you to an external page) or just download the latest Video dynamic framework here(link takes you to an external page).

Once you've downloaded and unpacked the XCFramework, navigate to your Xcode project's General settings page. Drag and drop TwilioVideo.xcframework onto the Frameworks, Libraries, and Embedded Content section. Ensure that "Copy items if needed" is checked and press Finish. Ensure that "Embed & Sign" is selected.

In your Build Settings, you will also need to modify Other Linker Flags to include -ObjC.

To allow a connection to a Room to be persisted while an application is running in the background, you must select the Audio, AirPlay, and Picture in Picture background mode from the Capabilities project settings page.

Background modes.

You can add Audio Processors for iOS by adding the https://github.com/twilio/twilio-audio-processors-ios repository as a Swift Package.

In your Build Settings, you will also need to modify Other Linker Flags to include -ObjC.


_10
source 'https://github.com/CocoaPods/Specs'
_10
_10
platform :ios, '12.2'
_10
_10
target 'TARGET_NAME' do
_10
pod 'TwilioAudioProcessors', '~> 5'
_10
end

Then run pod install to install the dependencies to your project.
