The iOS framework for Agora operates as a singleton to provide communication functionality so you will set up your controller to provide instances of the AgoraRtcEngineKit. Add buttons for muting local video, muting local audio, and hangup. In Main.storyboard add a new view controller with two subviews: one for localVideo, another for remoteVideo. Add the following keys.įor Camera write: “Please let us use your camera.”įor Microphone write: “Please let us use your microphone.” Integrating SDKĪdd a constant at the top of your AppDelegate.swift: The next step is to enable permissions for you to access the devices video calling uses to create calls: camera and microphone. If you have, run:Īdd the following to your Podfile: platform :ios, ‘9.0’ use_frameworks! target ‘Your App’ do pod ‘AgoraRtcEngine_iOS’ end
If you do not have Cocoapods installed, run: brew install cocoapods. If you haven’t already brewed, right now is a great time to start.

Key to our implementation is the desire to arrange the views for multiple members in a single video call so that the layout scales whenever the number of members increases or decreases! In your implementation, you will use an instance of UIStackView. In your app you will implement the following basic features for 1) setting up, 2) joining a channel, 3) muting / unmuting a user, and 4) scaling a layout for multiple members on the screen with UIStackView. In this basic tutorial, you will get up and running in a multiple member video chat in iOS 12 with Swift 5, Apple’s latest version of its brand new programming language.
In contrast with competitors, Agora’s rich, low-latency group chat is built on top of Agora’s Software Defined Real-Time Network, a technology that leverages algorithms to find the best way to route your video streaming calls! Agora’s Video Chat SDK is one of the easiest ways to enable multiple member video calling.
