Steps to Create a Video Calling App Using Agora:

When it comes to creating a video calling app using Agora, there are some steps to follow including:

  1. Setting Up an Agora Account: First, you need to set up an account on the website successfully. Once you do this, you need to create a project and look for it in the console. Now it is time to prepare the app id and the app certificate before you go to the next step.
  2. Integration of Stream Dashboard: The next step is all about integrating Stream Dashboard for implementing first-class integration of Agora. It is necessary to make Agora work as a server component that can handle token generation and more. It involves a few processes ranging from heading over to the Dashboard and login in, creating a new app, or selecting your app by name, selecting Ext. Video Integration and selecting the Agora tab. To go with these steps effectively, first, you need to enable the integration through the toggle to see the green Agora Enabled badge at the top. Next, you need to enter the credentials from the agora console. Here it is necessary to enter the aforementioned app id and app certificate from the agora console to continue the process.
  3. Setting Up Basic App Architecture: The integration of the video calling app using Agora requires a few preliminary setups. Otherwise, you will be unable to get a clear overview of the overall architecture. For instance, before you go deeper into the process of building the video calling app using Agora, you need to import the Agora SDK into the project. To do it you can use Swift Package Manager (SPM).
  4. Basic UI Layout: When it comes to setting up the basic UI, the SDKs will provide you with a lot of assistance in creating the best view for calls. When you will start creating the view for calls, you will be able to see some UI elements along with some participants. So, the UI components include a vertical list of all call participants, the user’s video which is placed at the top right above the other content, and a row of buttons at the bottom to control certain call elements such as toggle audio and video and end call. Creating basic UI layout involves several ranging from creating a view for call participants, creating a view of the users’ video, combining everything with the call view, creating the custom channel header to constructing the call overlay for the channel.
  5. Initiate Call with Channel Update: When it comes to initiating a video call, every time the channel will hold all necessary information about the call. This is a basic approach to a video calling app. It will help you know about all members of the channel who can join. But, here you need to do a few things such as watching the channel for updates, handling the updates in the local state for updating the UI of an ongoing call, and updating the channel state when a call will start or end. Firstly, you need to create a little helper function that can help you take care of watching a channel, for handling the channel updates and data you need to create a new Swift file and fill it with a String extension that can hold a few constants that you will need. Updating the channel state does not require very complex coding and there are several ways to do it.
  6. Integration of the Agora SDK: Once, everything is prepared, finally it is time to integrate the Agora SDK. To do this, you need to fill in the methods with the relevant code. There are separate codes and methods for starting and joining a call, leaving a call, muting audio and video, and listening for updates during a call.
