Telegram iOS Source Code Compilation Guide

We welcome all developers to use our API and source code to create applications on our platform. There are several things we require from all developers for the moment.

Creating your Telegram Application

1. Obtain your own api_id for your application.
2. Please do not use the name Telegram for your app — or make sure your users understand that it is unofficial.
3. Kindly do not use our standard logo (white paper plane in a blue circle) as your app's logo.
4. Please study our security guidelines and take good care of your users' data and privacy.
5. Please remember to publish your code too in order to comply with the licences.

Quick Compilation Guide

Get the Code

git clone --recursive -j8 https://github.com/TelegramMessenger/Telegram-iOS.git

Setup Xcode

Install Xcode (directly from https://developer.apple.com/download/applications or using the App Store).

Adjust Configuration

1. Generate a random identifier:

openssl rand -hex 8

2. Create a new Xcode project. Use Telegram as the Product Name. Use org.{identifier from step 1} as the Organization Identifier.
3. Open Keychain Access and navigate to Certificates. Locate Apple Development: [email protected] (XXXXXXXXXX) and double tap the certificate. Under Details, locate Organizational Unit. This is the Team ID.
4. Edit build-system/template_minimal_development_configuration.json. Use data from the previous steps.

Generate an Xcode project

python3 build-system/Make/Make.py \
    --cacheDir="$HOME/telegram-bazel-cache" \
    generateProject \
    --configurationPath=build-system/template_minimal_development_configuration.json \
    --xcodeManagedCodesigning

Advanced Compilation Guide

Xcode

1. Copy and edit build-system/appstore-configuration.json.
2. Copy build-system/fake-codesigning. Create and download provisioning profiles, using the profiles folder as a reference for the entitlements.
3. Generate an Xcode project:

python3 build-system/Make/Make.py \
    --cacheDir="$HOME/telegram-bazel-cache" \
    generateProject \
    --configurationPath=configuration_from_step_1.json \
    --codesigningInformationPath=directory_from_step_2

IPA

1. Repeat the steps from the previous section. Use distribution provisioning profiles.
2. Run:

python3 build-system/Make/Make.py \
    --cacheDir="$HOME/telegram-bazel-cache" \
    build \
    --configurationPath=...see previous section... \
    --codesigningInformationPath=...see previous section... \
    --buildNumber=100001 \
    --configuration=release_arm64

Tips

Codesigning is not required for simulator-only builds

Add --disableProvisioningProfiles:

python3 build-system/Make/Make.py \
    --cacheDir="$HOME/telegram-bazel-cache" \
    generateProject \
    --configurationPath=path-to-configuration.json \
    --codesigningInformationPath=path-to-provisioning-data \
    --disableProvisioningProfiles

Versions

Each release is built using a specific Xcode version (see versions.json). The helper script checks the versions of the installed software and reports an error if they don't match the ones specified in versions.json. It is possible to bypass these checks:

python3 build-system/Make/Make.py --overrideXcodeVersion build ... # Don't check the version of Xcode
