Yes. Since Swift 6.3, the open-source Swift project has provided an official Swift SDK for Android that cross-compiles Swift into native Android code. But it is a compiler and platform SDK, not an Android version of Xcode: it does not bring Apple’s SwiftUI, UIKit, or iOS frameworks to Android. You can use Swift for Android libraries and application logic, but Android APIs and app packaging still involve Android-specific tools and often Kotlin or Java. For Android-first development, Kotlin remains the lower-friction choice.
What “official Swift support for Android” means
Swift began at Apple and is now an open-source language and project. The Swift Android workgroup announced preview SDK releases in October 2025; Swift 6.3 included the first official release of the Swift SDK for Android. The current Swift platform-support page lists Android 9 (API level 28) as the minimum deployment version. Swift’s preview announcement, the Swift 6.3 release announcement and the platform-support page describe that status.
“Official” here means supported by the Swift project and distributed through Swift.org. It does not mean Apple has released an Android edition of Xcode or made its iOS frameworks available on Android.
How Swift code runs in an Android app
The official SDK lets a desktop host cross-compile Swift for Android. In broad terms, the toolchain compiles Swift source for an Android target, while the Android NDK provides native headers, system libraries and linker tools. The result can be a native library, such as a shared .so file, or an executable. A normal app can package Swift libraries and load them from its Android application.

Three practical ways to use Swift on Android
1. Put Swift logic behind a Kotlin or Java app
This is the conservative route: build the interface and use Android APIs from Kotlin or Java, and put portable logic in Swift. Suitable candidates include business rules, data processing and compatible Swift packages. The Swift output can be included as native libraries, with Kotlin or Java calling into exposed functions through generated bindings or JNI. This lets a team reuse Swift where it makes sense without treating the entire Android platform as a Swift environment.
2. Write more of the app in Swift and bridge to Android APIs
You can use Swift for more application code, but Android’s platform APIs and most of its libraries are exposed through Java and Kotlin. Accessing them from Swift therefore involves interoperability tooling, bindings and, in many cases, some Kotlin or Java glue. The Swift Android work describes tools including swift-java, jextract and wrap-java; JNI is the lower-level native bridge. Generated bindings can reduce boilerplate, but they do not erase differences in types, nullability, exceptions, object lifetimes or asynchronous APIs. See Swift’s overview of the Android SDK and its announcement of the Android SDK work.
3. Use a cross-platform framework such as Skip
Skip offers a Swift- and SwiftUI-oriented way to target iOS and Android. Its Lite mode transpiles Swift to Kotlin; its Fuse mode compiles Swift natively for Android using the Swift SDK. Skip describes mapping SwiftUI-style code to native SwiftUI on Apple platforms and Jetpack Compose on Android. That is Skip’s implementation and workflow—not Apple’s SwiftUI running unchanged on Android. Check Skip’s overview, its native Swift documentation and the Skip repository for the details of each mode.

Swift on Android does not mean SwiftUI or iOS frameworks are portable
The Swift SDK supplies Android compilation support; it does not bundle Apple’s SwiftUI, UIKit, Xcode project templates or the full Apple SDK ecosystem. Swift language code may be portable while the frameworks it depends on are not. An iOS app built around SwiftUI, UIKit, CoreBluetooth, CoreLocation, AVFoundation, Metal, Core ML or Apple-only services cannot simply be recompiled and expected to work on Android.
Frameworks can supply Android-specific UI implementations or translation layers. If a framework advertises SwiftUI-style development on Android, confirm whether it translates or recreates that interface using Android UI technology, which APIs it supports, and what platform-specific code remains your responsibility.
What you need for the official SDK setup
The official guide’s sample workflow uses Swift 6.3.3. Its commands and download checksum are specific to that release, so do not treat them as timeless installation instructions. The guide requires a matching Swift toolchain, the Swift SDK for Android, the Android SDK and an Android NDK. It specifies Android NDK LTS 27d or later. A device or emulator is needed to test a deployed app.
- A supported desktop host, such as macOS or Linux, to cross-compile.
- A Swift toolchain that matches the Swift Android SDK version.
- The Android SDK and the required Android NDK.
- A project setup that builds and packages the native output for its target Android architectures.
For an initial toolchain installation, the guide demonstrates swiftly:

swift --versionlatest is convenient for trying the setup, but it can change over time. Pin toolchain and dependency versions for repeatable builds. The guide’s Swift 6.3.3 SDK installation example is:
swift sdk install
https://download.swift.org/swift-6.3.3-release/android-sdk/swift-6.3.3-RELEASE/swift-6.3.3-RELEASE_android.artifactbundle.tar.gz
--checksum
d160cc3206dd1886dae3fef2337af5e25ec034692cd0ec225721c56cc69da7f5Then check that Swift sees the installed SDK:
swift sdk listFor that example release, the guide says the SDK appears as swift-6.3.3-RELEASE_android. If the NDK is installed somewhere other than the expected location, set its path before running the guide’s setup steps:
export ANDROID_NDK_HOME=/path/to/android-ndkUse the setup script and any host-specific directions from the current official getting-started guide; its exact instructions can change between releases.
Build Swift for Android and package it with Gradle
The integration documentation demonstrates building for the Android API 28 AArch64 target like this:
Recommended Free Tools
swift build --swift-sdk aarch64-unknown-linux-android28It also shows a Gradle task invoking a Swift release build with the static Swift standard library:
tasks.register<Exec>("buildSwiftLibrary") {
workingDir = file("${rootDir}/swift")
commandLine(
"swift", "build",
"--swift-sdk", "aarch64-unknown-linux-android28",
"-c", "release",
"--static-swift-stdlib"
)
}That snippet illustrates connecting the build systems; a complete app still needs project-specific tasks to place outputs in the right Android source set, load them and expose a callable interface. The official Android integration documentation describes copying a generated shared library into an Android project’s jniLibs directory.
A normal app must build and package the native libraries for the architectures it intends to support. The exact target architectures and packaging configuration depend on the Swift SDK release and Android project. Confirm them for your chosen versions rather than assuming a single library will cover every device.
The getting-started guide also demonstrates pushing a C++ runtime library to a device and launching a command-line executable with adb. That is a useful toolchain demonstration, not the same as shipping a distributable app. In an app, the Swift libraries are packaged into the APK or app bundle and loaded by the Android application.

Limits to check before choosing Swift for an Android project
Android APIs and ecosystem access
A successful Swift build does not by itself give the code access to Android UI, permissions, notifications, storage, services or third-party Android libraries. Those features need Android integration, whether directly through Java interoperability and JNI, through a Kotlin or Java host, or through a framework that supplies the necessary abstractions.
Lifecycle, concurrency and device behavior
Swift concurrency does not remove Android’s lifecycle rules. Test activity and process recreation, cancellation, background work, UI-thread access, configuration changes, services and permission callback lifetimes. These are app-level behaviors, not guarantees supplied by compiling Swift successfully.
Tooling and debugging
Android Studio remains centered on Android’s conventional project workflow; Swift support is not equivalent to its first-class Kotlin experience. Swift’s Android documentation identifies IDE integration, including Android Studio and SourceKit-LSP, as an area of development. Expect some Swift build, navigation or debugging work to happen outside the smooth Kotlin workflow, and evaluate the tools against the needs of your team. Swift’s SDK overview discusses the integration landscape.
Package compatibility
A Swift package is not Android-compatible just because it uses Swift. Packages that rely on platform-neutral language features or portable functionality are better candidates than packages tied to Apple-only frameworks. Even when a package builds, verify that the Android implementation provides the features your app needs; successful compilation does not establish feature parity.

How Swift compares with the main Android and cross-platform choices
| Approach | Main language | Android UI strategy | Best fit |
|---|---|---|---|
| Official Swift SDK alone | Swift | Build through Android APIs and bindings, or provide a separate UI layer | Swift libraries, shared logic or specialist native code |
| Swift library with Kotlin or Java host | Swift plus Kotlin or Java | Jetpack Compose or Android Views | Incremental Swift reuse in a conventional Android app |
| Skip Lite | Swift, transpiled to Kotlin | Skip’s SwiftUI-oriented workflow maps to Compose on Android | Teams seeking a Swift-oriented cross-platform workflow through generated Kotlin |
| Skip Fuse | Swift compiled natively for Android | Skip’s SwiftUI/Compose integration | Teams wanting more native Swift in a Skip-based workflow |
| Kotlin Multiplatform | Kotlin, with Swift as needed on iOS | Native Android UI, including Compose | Shared logic with strong alignment to Android’s Kotlin ecosystem |
| Flutter | Dart | Flutter’s cross-platform widget system | Teams adopting Dart and a shared UI framework |
| React Native | JavaScript or TypeScript | React Native components, with native modules where needed | Teams with substantial JavaScript or TypeScript experience |
Android’s own documentation describes Kotlin as fully supported for Android development and Android Studio as providing first-class Kotlin support. See Android’s Kotlin overview. Its Kotlin Multiplatform setup guide explains how teams can share Kotlin modules while keeping platform-native UI. Framework comparisons are workflow choices, not performance rankings; no one approach is best for every team.
Which approach should you choose?
- You already have substantial Swift code or Swift expertise: test the official SDK for portable libraries and shared logic. If you need a SwiftUI-oriented cross-platform app, evaluate Skip’s Lite and Fuse modes against your framework dependencies and Android requirements.
- Android is the primary platform: start with Kotlin and standard Android tooling unless a specific Swift advantage justifies the extra integration work.
- You want shared code but native platform UI: compare a Swift library plus Kotlin host with Kotlin Multiplatform. The right balance depends on which language and codebase your team can maintain.
- You need a cross-platform UI and do not need Swift reuse: Flutter or React Native may fit better if your team already works in Dart or JavaScript/TypeScript and their ecosystem suits the product.
Swift on Android is real: the official SDK compiles Swift for Android and enables native libraries to be included in apps. The crucial distinction is that the SDK is a foundation, not a turnkey replacement for Kotlin, Android Studio and Android’s platform ecosystem. Choose it for a concrete Swift-reuse or framework benefit, and plan the Android-specific work at the same time.
