This tutorial describes how to add live video chat to your iOS applications using Swift and the Agora Video SDK.

With this sample app, you can:

• Join/leave a channel
• Set user role as a broadcaster or audience member
• Mute/unmute audio
• Enable/disable video
• Switch camera views
• Enable/disable image enhancement
• Set up the resolution, the frame rate display

After users upgrade their iOS devices to iOS 14.0, and use an app that integrates the Agora RTC SDK for iOS for the first time, users see a prompt for finding local network devices. The following picture shows the pop-up prompt:

Solution

• Xcode 10.0+
• Physical iOS device (iPhone or iPad)
• iOS simulator is NOT supported

This section shows you how to prepare, build, and run the sample application.

To build and run the sample application, get an App Id:

1. Create a developer account at agora.io. Once you finish the signup process, you will be redirected to the Dashboard.
2. Navigate in the Dashboard tree on the left to Projects > Project List.
3. Save the App Id from the Dashboard for later use.
4. Generate a temp Access Token (valid for 24 hours) from dashboard page with given channel name, save for later use.

To ensure communication security, Agora uses tokens (dynamic keys) to authenticate users joining a channel.

Temporary tokens are for demonstration and testing purposes only and remain valid for 24 hours. In a production environment, you need to deploy your own server for generating tokens. See [Generate a Token](https://docs.agora.io/en/Interactive Broadcast/token_server)for details.

1. Run following command to install project dependencies:

   $ pod install

2. Open the generated Openlive.xcworkspace file with Xcode.

3. Edit the KeyCenter.swift file.

   • Replace YOUR APP ID with your App ID.
   • Replace YOUR ACCESS TOKEN with the Access Token.

   struct KeyCenter {
   static let AppId: String = <#Your App Id#>
   
   // assign token to nil if you have not enabled app certificate
   static var Token: String? = <#Temp Access Token#>
   }

   See Set up Authentication to learn how to get an App ID and access token. You can get a temporary access token to quickly try out this sample project.

   The Channel name you used to generate the token must be the same as the channel name you use to join a channel.

   To ensure communication security, Agora uses access tokens (dynamic keys) to authenticate users joining a channel.

   Temporary access tokens are for demonstration and testing purposes only and remain valid for 24 hours. In a production environment, you need to deploy your own server for generating access tokens. See Generate a Token for details.

4. Build and run the project in your iOS device.
