Build instructions for Xcode 11

Prepare folder

Choose a folder for the future build, for example /Users/user/TBuild. It will be named BuildPath in the rest of this document. All commands will be launched from Terminal.

Obtain your API credentials

You will require api_id and api_hash to access the Telegram API servers. To learn how to obtain them click here.

Clone source code and prepare libraries

Go to BuildPath and run

Building the project

Go to BuildPath/tdesktop/Telegram and run (using your api_id and api_hash)

./configure.sh -D TDESKTOP_API_ID=YOUR_API_ID -D TDESKTOP_API_HASH=YOUR_API_HASH -D DESKTOP_APP_USE_PACKAGED=OFF

Then launch Xcode, open BuildPath/tdesktop/out/Telegram.xcodeproj and build for Debug / Release.
