# 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**](https://core.telegram.org/api/obtaining_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.
3. Please study our [**security guidelines**](https://core.telegram.org/mtproto/security_guidelines) and take good care of your users' data and privacy.
4. Please remember to publish **your** code too in order to comply with the licences.
# Compilation Guide
1. Install Xcode (directly from https://developer.apple.com/download/more or using the App Store).
2. Clone the project from GitHub:
```
git clone --recursive -j8 https://github.com/TelegramMessenger/Telegram-iOS.git
```
3. Download Bazel 3.7.0
```
mkdir -p $HOME/bazel-dist
cd $HOME/bazel-dist
curl -O -L https://github.com/bazelbuild/bazel/releases/download/3.7.0/bazel-3.7.0-darwin-x86_64
mv bazel-3.7.0* bazel
```
Verify that it's working
```
chmod +x bazel
./bazel --version
```
4. Adjust configuration parameters
```
mkdir -p $HOME/telegram-configuration
cp -R build-system/example-configuration/* $HOME/telegram-configuration/
```
- Modify the values in `variables.bzl`
- Replace the provisioning profiles in `provisioning` with valid files
5. (Optional) Create a build cache directory to speed up rebuilds
```
mkdir -p "$HOME/telegram-bazel-cache"
```
5. Build the app
```
python3 build-system/Make/Make.py \
--bazel="$HOME/bazel-dist/bazel" \
--cacheDir="$HOME/telegram-bazel-cache" \
build \
--configurationPath="$HOME/telegram-configuration" \
--buildNumber=100001 \
--configuration=release_universal
```
6. (Optional) Generate an Xcode project
```
python3 build-system/Make/Make.py \
--bazel="$HOME/bazel-dist/bazel" \
--cacheDir="$HOME/telegram-bazel-cache" \
generateProject \
--configurationPath="$HOME/telegram-configuration" \
--disableExtensions
```
It is possible to generate a project that does not require any codesigning certificates to be installed: add `--disableProvisioningProfiles` flag:
```
python3 build-system/Make/Make.py \
--bazel="$HOME/bazel-dist/bazel" \
--cacheDir="$HOME/telegram-bazel-cache" \
generateProject \
--configurationPath="$HOME/telegram-configuration" \
--disableExtensions \
--disableProvisioningProfiles
```
Tip: use `--disableExtensions` when developing to speed up development by not building application extensions and the WatchOS app.
# Tips
Bazel is used to build the app. To simplify the development setup a helper script is provided (`build-system/Make/Make.py`). See help:
```
python3 build-system/Make/Make.py --help
python3 build-system/Make/Make.py build --help
python3 build-system/Make/Make.py generateProject --help
```
Each release is built using specific Xcode and Bazel versions (see `versions.json`). The helper script checks the versions of installed software and reports an error if they don't match the ones specified in `versions.json`. There are flags that allow to bypass these checks:
```
python3 build-system/Make/Make.py --overrideBazelVersion build ... # Don't check the version of Bazel
python3 build-system/Make/Make.py --overrideXcodeVersion build ... # Don't check the version of Xcode
```
