How To: Build an Augmented Reality Remote Assistance App

This guide provides step-by-step instructions on how to build an iOS app that leverages ARKit and video chat to create an interactive experience for remote assistance. The app is designed for two users in separate physical locations, where one user receives remote assistance while the other provides it. The app includes features such as channel creation, video chat functionality, touch gesture handling, data transmission, displaying gestures in augmented reality, and undo functionality. The guide assumes a basic to intermediate understanding of Swift and iOS SDK, along with ARKit and Augmented Reality concepts. It also requires an Agora Developer Account and hardware such as a Mac with Xcode and two iOS devices (iPhone 6S or newer and iPad 5th Generation or newer).
