This tutorial guides the development of a video calling app using iOS platform, Xcode, and Swift. The app integrates the Video SDK library with CocoaPods for seamless video calling functionality. It includes two primary screens: the Join Screen, which allows users to create new meetings or join existing ones, and the Meeting Screen, which features local and remote participant views along with essential meeting controls like enabling/disabling the microphone and camera, and leaving the meeting. The app also handles meeting interactions, including joining, leaving, and switching between participants. By following this tutorial, developers can gain hands-on experience in iOS app development, integrating external libraries, and handling meeting interactions, ultimately creating a video calling app with robust features.
