Project Structure

At its heart, the project integrates both Swift Package Manager (SPM) for Swift code and Gradle for Android application code.

Sources

📦 Project Root
├── 📄 Package.swift              # Swift package configuration
├── 📂 Sources
│   ├── 📂 App
│   |   ├── 📄 App.swift          # Entry point for the application
│   |   └── 📂 Activities
│   |       └── 📄 MainActivity.swift    # Main Android activity
│   └── 📂 AppManifest
│   |    └── 📄 Manifest.swift    # Proxy target for manifest declared in App
│   └── 📂 AppUI
│       └── 📄 AppUI.swift        # Proxy target which points to App

App target contains your main application code. Read more in → entry point section.

AppManifest target is a proxy target which you shouldn't modify, it is required to generate the AndroidManifest.xml file for your app.

AppUI target is a proxy target which also shouldn't be modified, it is required to generate the Android library module for your app.

Application

├── 📂 Application
│   ├── 📄 settings.gradle.kts    # App project settings
│   ├── 📄 build.gradle.kts       # Root app build configuration
│   └── 📂 androidapp

│               └── 📂 res                  # Assets

Automatically generated Android application (a Gradle project) which could be opened in Android Studio. Files here are generated once and then managed by you.

Library

├── 📂 Library
│   ├── 📄 settings.gradle.kts    # Lib project settings
│   ├── 📄 build.gradle.kts       # Root lib build configuration
│   └── 📂 appui
│       ├── 📄 build.gradle.kts   # Android lib module build configuration
│       └── 📂 src
│           └── 📂 main
│               ├── 📄 AndroidManifest.xml  # Auto-Generated Manifest
│               ├── 📂 java                 # Auto-Generated Kotlin classes
│               └── 📂 jniLibs              # Native libraries for JNI

Automatically generated Android library (a Gradle project) which is imported into the Application project. All files here are managed by Swift Stream IDE.

.devcontainer

├── 📂 .devcontainer
│   └── 📄 devcontainer.json      # Development container configuration

Contains configuration for your development container.

devcontainer.json contains Swift, Gradle, SDK, and NDK versions used within the container. You can modify it to fit your needs.

It is more convenient to change these settings via the Swift Stream IDE sidebar panel.

.sourcekit-lsp

├── 📂 .sourcekit-lsp
│   └── 📄 config.json            # SourceKit-LSP server configuration

Contains configuration for SourceKit-LSP, which provides Swift language support in the IDE. It is necessary for the correct code completion, error highlighting, and other language features.

.vscode

└── 📂 .vscode
    └── 📄 android-stream.json    # VS Code Android development settings

Contains the Swift Stream IDE settings to build your project correctly.

You can adjust compileSDK and minSDK versions here.

soMode setting is set to Packed and it should be left unchanged
