This is a free and open-source Skip dual-platform app project.

This project is both a stand-alone Swift Package Manager module, as well as an Xcode project that builds and translates the project into a Kotlin Gradle project for Android using the skipstone plugin.

Building the module requires that Skip be installed using Homebrew with brew install skiptools/skip/skip.

This will also install the necessary Skip prerequisites: Kotlin, Gradle, and the Android build tools.

Installation prerequisites can be confirmed by running skip checkup. The project can be validated with skip verify.

Xcode and Android Studio must be downloaded and installed in order to run the app in the iOS simulator / Android emulator. An Android emulator must already be running, which can be launched from Android Studio's Device Manager.

The project can be opened and run in Xcode from Project.xcworkspace, which also enabled parallel development of any Skip libary dependencies.

To run both the Swift and Kotlin apps simultaneously, launch the "BluetoothExplorer App" target from Xcode. A build phases runs the "Launch Android APK" script that will deploy the Skip app to a running Android emulator or connected device. Logging output for the iOS app can be viewed in the Xcode console, and in Android Studio's logcat tab for the transpiled Kotlin app, or using adb logcat from a terminal.

The module can be tested using the standard swift test command or by running the test target for the macOS destination in Xcode, which will run the Swift tests as well as the transpiled Kotlin JUnit tests in the Robolectric Android simulation environment.

Parity testing can be performed with skip test, which will output a table of the test results for both platforms.
