+# 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](https://github.com/tdlib/td#macos).
+
+For example of usage take a look at our [Swift example](https://github.com/tdlib/td/tree/master/example/swift).
+
+To compile `TDLib` you will need to:
+* Install the latest Xcode command line tools.
+* Install other build dependencies, for example, using [Homebrew](https://brew.sh):
+```
+brew install gperf cmake
+```
+* 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](https://github.com/pybee/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 (arv7, armv7s, arm64) and even on a simulator.
+We use [CMake/iOS.cmake](https://github.com/tdlib/td/blob/master/CMake/iOS.cmake) toolchain, other toolchains may work too.
+
+Built libraries will be store in `tdjson` directory.
+
+Documentation for all available classes and methods can be found at https://core.telegram.org/tdlib/docs.
