Environment

Swift

1. Download and install the .pkg toolchain from https://www.swift.org/install
2. Get the SDK URL from https://github.com/swift-android-sdk/swift-android-sdk.git
3. The toolchain and SDK must be the same version (for development snapshots, the date and version must match)
4. Install the SDK with swift sdk install

Android

1. Install sdkmanager: brew install --cask android-commandlinetools
2. Set up paths to commands:
   • echo -n 'export ANDROID_HOME=/opt/homebrew/share/android-commandlinetools\n' >> ~/.zshrc
   • echo -n 'export PATH=${ANDROID_HOME}/platform-tools:$PATH\n' >> ~/.zshrc
   • echo -n 'export PATH=${ANDROID_HOME}/emulator:$PATH\n' >> ~/.zshrc
3. Install dependancies: sdkmanager --install 'system-images;android-35;default;arm64-v8a' 'emulator' 'cmdline-tools;latest' 'build-tools;35.0.1' 'platforms;android-35' 'platform-tools' 'ndk;28.2.13676358'
4. Create an emulator: avdmanager create avd -n test -k 'system-images;android-35;default;arm64-v8a' and launch emulator -avd test

Configure

1. Set your SDK path at <android-sdk> and run script: ANDROID_NDK_HOME=/opt/homebrew/share/android-commandlinetools/ndk/28.2.13676358 ~/Library/org.swift.swiftpm/swift-sdks/<android-sdk>.artifactbundle/swift-android/scripts/setup-android-sdk.sh
2. Modify makefile arguments according to your preferences
3. Create a signing key with make keystore

SPM to apk

1. Modify build: aarch64 to build: armv7 aarch64 x86_64 if you want to build all three architectures
2. Add missing dependencies to LIBRARIES if you want to use Foundation library, for example. You can identify missing dependencies by checking for dlopen errors in adb logcat
3. Finally, make run to build, archive, install, run and log application
