Usage

1. Make sure that you have Swift Android Toolchain. You can either build it or download pre-build version.

2. Reveal the NDK version inside file NDK_VERSION, which located at the root of the Swift Toolchain you downloaded or built on step 1.

3. Make sure that you have a symlink at /usr/local/ndk/$NDK_VERSION to appropriate NDK bundle. Where $NDK_VERSION is the NDK version from file NDK_VERSION you viewed on step 2.

   sudo mkdir -p /usr/local/ndk
   sudo ln -vsi ~/Library/Android/sdk/ndk/21.X.YYYZZZ /usr/local/ndk/21.X.YYYZZZ

4. Make sure that NDK version defined in Gradle build configuration file (See: Android/app/build.gradle) in property android.ndkVersion matches NDK version from file you viewed on step 2. Update property android.ndkVersion if needed.

5. Make sure that the absolute paths to NDK headers in sources matching NDK version inside file NDK_VERSION.

6. Copy file example.swiftToolchain.rc to swiftToolchain.rc. Update file swiftToolchain.rc with proper paths:

   • SaSwiftToolchainDirPath - Path to Swift Toolchain you downloaded or built on step 1.

7. Install "Protocol buffers" for Java and Swift sources generation brew install protobuf swift-protobuf

8. (Optional) Generate models: Scripts/GenerateModels.sh

9. Open iOS/HelloJNI.xcodeproj in Xcode and run it on Device or iOS Simulator.

10. Open folder Android in Android Studio and run it on Device or Android Simulator.
