Build for iOS

Below are instructions for building TDLib for iOS, watchOS, tvOS, and also macOS.

If you need only a macOS build, take a look at our build instructions for macOS.

For example of usage take a look at our Swift example.

To compile TDLib you will need to:

• Install the latest Xcode via xcode-select --install or downloading it from Xcode website. It is not enough to install only command line developer tools to build TDLib for iOS.
• Install other build dependencies using Homebrew:

brew install gperf cmake coreutils

• If you don't want to build TDLib for macOS, you can pregenerate required source code files using CMake prepare_cross_compiling target:

cd <path to TDLib sources>
mkdir native-build
cd native-build
cmake ..
cmake --build . --target prepare_cross_compiling

• Build OpenSSL for iOS, watchOS, tvOS and macOS:

cd <path to TDLib sources>/example/ios
./build-openssl.sh

Here we use scripts from Python Apple support, but any other OpenSSL builds should work too. Built libraries should be stored in third_party/openssl/<platform>, because the next script will rely on this location.

• Build TDLib for iOS, watchOS, tvOS and macOS:

cd <path to TDLib sources>/example/ios
./build.sh

This may take a while, because TDLib will be built about 10 times. Resulting library for iOS will work on any architecture (armv7, armv7s, arm64) and even on a simulator. We use CMake/iOS.cmake toolchain, other toolchains may work too.

Built libraries will be store in tdjson directory.
