How to Launch Gcore’s Real-Time Communications for iOS

In a fast-paced digital world where every second matters, the strength of real-time communication or RTC communications rests in the ability to cross distance and time, instantly bringing people together and changing the way things are done like never before.

Gcore’s Real-Time Communications,  or Gcore “RTC” for short, is cutting-edge technology that enables real-time video and audio transmission within your iOS apps.

Real-time communications are essential because they allow for quick and seamless information sharing, enabling efficient cooperation, offering fast support, and enabling data-driven decision-making.

Whether you’re building a video conferencing app, a live streaming platform, or integrating communication features into your existing software, Gcore’s real-time communication provides a robust and reliable solution.

RTC modules improve efficiency, and productivity, and build a unified experience across all domains of human activity, thus becoming an integral aspect of modern civilization.RTC communications

What is Real-Time Communications or RTC Communications?

It’s important to know what RTC means and how it changed the world. Let’s start off by explaining the concept and how it changed from its early days.

What is RTC?

The ability of multiple individuals to share information or data in real-time across a network or the internet is referred to as “Real-Time Communication.”  RTC technologies offer instant and smooth communication between people or machines, enabling interactive and time-sensitive activities.

One of the most prevalent uses of RTC is real-time audio and video communication, which allows users to hold face-to-face interactions via video conferencing platforms. These technologies have transformed how people work, communicate, and interact with one another around the world.

RTC relies on several protocols and technologies to support real-time data transfer, including WebRTC (Web Real-Time Communication), SIP (Session Initiation Protocol), and RTP (Real-time Transport Protocol). 

It’s widely used in applications such as online meetings, audio and video chatting, online gaming, live streaming, and various other real-time interactive services requiring low latency and high-quality communication. 

Constant Evolution

The introduction of the electric telegraph in the nineteenth century enabled real-time transmission of coded messages over large distances, revolutionizing communication over long distances. Later, with the introduction of the telephone in the late 1800s, real-time voice communication became available, greatly expanding human connectivity.

With the introduction of computers and the establishment of the internet in the mid-twentieth century, tremendous changes occurred. The Advanced Research Projects Agency Network was established in the 1960s, defining the groundwork for the current internet. 

As technology advanced, real-time communication developed through early instant messaging platforms, and the first internet-based phone and video communication services appeared in the 1990s.

With smartphones and high-speed internet growth, RTC communications achieved new heights in the twenty-first century. Popular messaging apps, video conferencing tools, and social media sites allow global real-time communications. 

RTC now plays an integral part in many sectors of life, from commercial collaborations to social connections, and it is expected to continue to expand as artificial intelligence, and cloud computing, advance, offering an even more interconnected and seamless future.

How to Use Gcore’s RTC Communications

Here’s a step-by-step guide on how you can utilize Gcore’s RTC in your applications:

Sign Up and Log In

Begin by creating a Gcore account on their website. This will provide you access to the RTC Software Development Kit, or “SDK” for short, and the API keys you’ll need to incorporate into your application.

Install Required Dependencies

Find out if you have the appropriate development environment for iOS development set up. Install the necessary development tools, such as Xcode.

Integrate the Proper Software Development Kit

For iOS, you can manually add the necessary frameworks to your Xcode program to incorporate the RTC software development kit. 

Initialize Gcore’s Client

Create an instance of the RTC client in your application’s code and configure it with your Gcore API keys. This will link you to Gcore’s RTC servers.

Implement User Authentication

Implement user authentication with Gcore’s authentication APIs to ensure a safe connection. Verify user identities and allow access to RTC features based on their login information.

Build a Compelling UI

Create an easy-to-use UI for real-time communication services. Include audio and video calling options, chat functionality, and any other related features.

Handle RTC Events

Create event handlers for RTC events, including incoming calls, network status changes, and call cancellations. These event handlers will assist you in adequately managing call statuses.

Implement Call Enhancements

To initiate audio and video calls among users, use the RTC software development kit’s APIs. Implement audio muting and unmuting, switching between front and back cameras, and video quality management based on network conditions.

Additionally, you can examine Gcore’s software development kit’s extra features, such as screen sharing, call recording, and real-time chat. These enhancements have the potential to improve the user experience significantly.

Final Testing Before Launch

Conduct comprehensive testing and debugging before launching your application with Gcore’s RTC features. To ensure smooth functioning, test the real-time communication functions in a variety of scenarios and devices.

Monitor Performance

Integrate analytics tools to track the success of your RTC features and learn about user behaviour. This will assist you in identifying areas for improvement and optimizing your application.

Stay Up-to-Date with Gcore’s Updates

Keep in mind that Gcore’s RTC software development kit may receive upgrades and improvements. 

Stay up to date by examining their documentation and developer resources regularly. Implementing new features can keep your application ahead of the competition.


You may effectively incorporate Gcore’s RTC  into your iOS app and provide your users with a unique real-time communication experience by following the methods indicated in this post. 

RTC will likely have a more critical role in defining how we communicate and engage in the digital world as technology advances.
