WebRTC on mobile, short for Web Real-Time Communication, stands as a dynamic technology revolutionizing browser-to-browser interaction. Its popularity has surged, especially in mobile app integration, fostering seamless and instantaneous connections. This guide immerses you in the realm of WebRTC on mobile, unraveling its essence, functionality, and guiding you through the steps to craft a WebRTC mobile app using freely available SDKs.
What is a WebRTC Mobile App?
A WebRTC mobile app leverages the WebRTC technology to enable real-time communication between devices. Unlike traditional communication methods, WebRTC allows for direct interaction between users, bypassing the need for intermediary servers in certain scenarios. This approach is particularly advantageous for applications requiring low latency, such as video conferencing, live streaming, and interactive gaming.
How does WebRTC work?
WebRTC facilitates browser-to-browser communication through a set of APIs (Application Programming Interfaces) and protocols. It allows audio and video communication, as well as data sharing, directly between browsers. Key components of WebRTC include:
The getUserMedia API serves as the gateway to a user’s multimedia realm, granting applications access to their camera and microphone. This fundamental component empowers WebRTC applications to capture the essence of real-time interactions, allowing users to engage through video calls and audio communication effortlessly.
At the heart of WebRTC lies the RTCPeerConnection, a critical component responsible for managing connections and ensuring the secure exchange of audio, video, and data between peers. This robust mechanism orchestrates the intricacies of establishing a reliable channel, fostering a secure environment for the seamless flow of multimedia elements and information.
The RTCDataChannel emerges as a pivotal feature, enabling peer-to-peer communication specifically tailored for arbitrary data exchange. This component goes beyond audio and video, providing a direct avenue for applications to share various forms of data in a peer-to-peer fashion. Whether it’s text messages, files, or other information, the RTCDataChannel ensures a versatile and efficient exchange between connected browsers.

How to Build a WebRTC Mobile App with Free SDKs?
Build a WebRTC iOS App
- Xcode: Ensure that Xcode, Apple’s integrated development environment, is installed on your Mac.
- CocoaPods: Install CocoaPods, a dependency manager for Swift and Objective-C projects, by executing the following command in your terminal:
sudo gem install cocoapods
Understanding of WebRTC:Acquaint yourself with fundamental WebRTC concepts, including signaling, peer connections, and SDP (Session Description Protocol).
Steps to Build a WebRTC iOS App
1. Create a New Xcode Project
Open Terminal and navigate to your desired directory. Execute the following commands:
open -a Xcode podfile
target 'MyWebRTCApp' do
pod 'WebRTC', '~> 1.1'
