What is telegram-ios?

This repository contains the source code for the official Telegram messaging app on iOS. It lets developers download, study, modify, and build their own version of the Telegram iPhone app. The main benefit is that instead of writing a chat application from scratch, a developer can start with a fully-featured, production-ready foundation and customize it to fit their needs. To get the app running, a developer downloads the code to a Mac computer and uses Apple's Xcode software to compile it. The project relies on a tool called Bazel to manage the build process, which essentially assembles all the raw code into a finished, working application. A helper script is included to simplify this process, but the developer still needs to provide their own API key and configuration files to make the app functional. This project is intended for developers who want to create a custom messaging experience. For example, a startup might use this code to build a niche, invite-only chat app for a specific community, keeping Telegram's familiar interface but adding unique features. Another developer might simply want to explore how a large-scale, secure messaging app handles features like encryption and media sharing. Telegram has a few specific rules for anyone using this code. You cannot name your custom app "Telegram" or use their standard logo, so users know your version is unofficial. You are also required to review their security guidelines to protect user privacy and to publish your own modified code, since the license requires it. Building the app also requires specific versions of Xcode and Bazel, though the included tools can help bypass those exact requirements if needed.
