ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

and i found that I need to install Universal frameworks but I always get an error

Answer 1

Steps to make it working:

1. Download an old Xcode , Xcode 7.x or older. this answer will help you and install it side by side with your up to date version.
2. Download iOS Universal Frameworks and install it using the Old Xcode Path. Use the Real Framework.
3. Download code from this unofficial but working version.
4. Open Telegram Xcode Project project file > Telegraph Target > Build Settings > Search For Header search paths > MtProotoKit>> make it recursive.
5. DO NOT accept the solution popup for POP framework error that will appear for you. Cancel it and run app regardless this error, it will run successfully.
6. set appID inside TGTelegramNetworking.m and Hash and appId inside TGTelegraph.mm to yours.
7. Enjoy!

NOTE: Take snapshots of your work or commit your repository after each update in project to avoid restarting the whole work if you have done something wrong in any step.
